You mean Chinese? I'm not really sure why they would release in Japanese there.

Nope, I do mean Japanese! It was very common in the 1990s for, for example, Mega Drive games to release in Hong Kong in Japanese packaging, with Japanese cartridge-shells, but with English in-game text. It went on for years! (Look up Asian releases for that console - you'll see it. :))

Yeah, just like the Hong Kong Tamagotchi Plus - the packaging looks identical to the Japanese one but PRETTY sure it is in english. I think th Hong Kong P1s are in english too but I think those have an American - style package if I'm not mistaken. Also English iD L had the original packaging (albeit desaturated into white) while the unit was English.

The thing about consoles and games is true too. While Wonderswan was a Japanese-exclusive console (to my knowledge), Hong Kong cartridges for it were in English.

Yeah, I found an image of the Hong Kong edition's packaging and sure enough it's literally just the Japanese packaging. Strange! I think it's safe to say they're in English given all the English menus and words in the instruction manual.

A small update: the US version of the V5 Celebrity actually displays a lot more in the ROM test than the earlier V5 versions, with a screen more reminiscent of the ROM version screen seen in later versions. Alongside a little sprite of Nyatchi the ROM version is displayed (on the one I saw the ROM version was 36.0, but there might be more ROM versions for the V5C!) as well as the region of the device (in this case "USA") and another number I'm not sure of the purpose of ("00" here).

This 00 - or sometimes 01 - appears in the ROM test screens of V6, 7 and 8, too. And probably the Dream Town Friends as well, but I've not seen a ROM test of that version as of yet. From what I can tell this is a revision number - unlike earlier versions where revisions are encoded in the ROM version (for example, 2.0 and 2.1 are different revisions of the European version of the V1), it seems as though the later versions split the version into two numbers, with the first representing the general / retail version of the Tamagotchi (the Music Star, Tama-Go and Friends have the ROM versions 6.0, 7.0 and 8.0) while the second number represents revisions. It also seems to split the region into a separate variable too - previously different regions used different ROM versions, but perhaps in later versions the regional differences were so minor that the only differences between the different regional variants was language and date format, so the ROM version itself was kept the same between releases.

The "general version number" concept slightly conflicts with the number displayed on the V5C since clearly the "V5.5" is not V36. I'm not really sure how to reconcile this discrepancy but I assume it just displays 36.0 because it's an international version, so it follows the ROM version numbering used in the Japanese models. It still begs the question of why there's a ".0" at all if revisions are handled by an additional variable, but I guess it's just to make room for the ".5" versions (which ironically never appeared again after the V5 Celebrity, though the Music Star was going to get a "refresh" version which was cancelled and there's some proof that the Tama-Go faced the same fate.

The Music Star had the (revision number) versions of 00 and 01, with the former being the original release and the latter being the second wave - there's subtle differences between these versions but the main difference is that the way in which money is passed down each generation is changed. I think I've heard the price of the Wild Guitar was lowered too.

The US version of the Tama-Go had the number 01 - I've yet to see whether the different regional releases yet. I'm not really sure why it didn't start at 00 this time, but maybe the number 00 was given to the prototype versions seen at the toy fair.

So far I've only seen "00" for the Friends, I think it was the US version. This definitely needs more investigation too, since the European version had different games and the Russian version needs to be investigated, too.

Both the Music Star and the Tama-Go also display a single "0" and the Music Star also has a small "32.0" beneath the word "Ver". I've no idea what any of these numbers mean, though.

---

One small update for the V2, too: it's been determined that version A.3 is a European version and that it used the early item names. It seems as though first wave V2s used this ROM version. The history behind the V2's release is a complicated one - apparently, the devices that were planned to release in America in March / April got redirected to Europe, perhaps to make up for the Tamagotchi shortage there, and the release was delayed until June. These "0th wave" V2s frequently used ROM versions with the earlier item names, just as the very early European ones did. So, if your V2 uses these early item names, it's probably version A.3 or earlier. We're still not sure on the exact number that was used by the early Connection V2s, though.

---

One last thing I thought I'd mention which I noticed recently! Some versions display a character on screen during a ROM test, but I hadn't noticed until recently that it seems like the character depends on what region the Tamagotchi was released in. European V4s display a little Pochitchi, while the American ones show Nyatchi!

Did you know? English and Japanese are not the only languages Tamagotchi are available in.

None of this post is my own findings! Lots of helpful people in the Discord introduced me to what I'm about to show you.

So, there's this video of a few Tamagotchi V2 glitches, and one of the glitches results in the Tamagotchi playing a sound I don't think I've heard anywhere else. It kinda sounds like the "victory" sound slowed down, to me.

I'd seen this video before, but upon rewatching last night I realised something I must have totally forgotten about: the Tamagotchi is in Spanish. I don't think I've ever seen a Spanish Tamagotchi anywhere else, but apparently most of the Connection versions had a Spanish release. I doubt a release like this is rare, but finding them on the English-speaking internet? Probably not so easy. There might be a whole treasure trove of version differences here which are yet to be uncovered - the Spanish versions also leave a bunch of gaps in the ROM versions list that we can hopefully fill in.

Spanish wasn't the only other language that got its own Tamagotchi release. Have you ever seen a Russian Tamagotchi Friends before? Later Tamagotchi releases had fewer revisional differences so I imagine the Russian version would play identically to an English Tamagotchi Friends aside from the language (though, the games did differ between the European and American releases - I guess, judging by the shell and the date format, that the Russian version was built upon the American version's ROM).

Got any more info on foreign language Tamagotchis like the Spanish releases? Aware of any other obscure Tamagotchi versions? I'd love to hear more about them.

i can confirm this is indeed russian, there are no Ukrainian letters, though they are very similar there are two or three distictive characters between russian and ukrainian. im actually looking into getting one but it may be hard.

An update! The PUMA V2 has a ROM version of "A2 H" (thanks to the Discord user that sent me this info!)

This one's a bit weird - the other known V2 versions are A.3, A.4 and A.5 (though there's at least another two versions on top of those). The PUMA version doesn't have a period between the A and the number, meaning this was probably the start of the convention that the V3 used, where the retail version number follows the letter A. What I'm not sure of the meaning of is the H - I don't have a clue why they chose this particular letter.

Hopefully we'll be hearing about what ROM version the GLAY Expo Plus used soon - if it's anything like the PUMA version I'm sure it'll contain a random letter too.

Time for perhaps the most bizarre update I've given - some new developer features have been discovered!

All this information comes from rjalda100, who discovered and tested the feature while trying to perform the region change procedure on a V1.

For those unfamiliar with region changing, it's a process you can perform on the American connection models in a similar manner to activating the debug mode - instead of shorting the JP3 solder jumper on the circuit board, however, JP1 and JP2 are shorted instead. I'm unsure about what happens if only one of these two jumpers are shorted; it'll be something to investigate in the future.

As Pirorirotchi demonstrated on page 3, region changing has the effect of switching the ROM version that's used with a different one - the data your Tamagotchi uses is changed from the data used in the American ROM to one used by European models. This isn't necessarily hugely remarkable by itself, though this recent discovery has given us new knowledge about what this feature was used for.

A few days ago rjalda100 was attempting to compare the two ROM versions of an American V1 - before region changing, the ROM version was found to be 4.2. After region changing and ROM testing again, the following screen was shown instead of what was expected:

rDGC6JR.png


This ROM version has never been observed before, and until this point all of the Japanese and worldwide releases in the Connection / Plus series used even integer version numbers - 0.0, 2.0, 2.1, 4.0, 4.2, 6.1, 8.0 and so on. The numbers at the bottom of the screen are also unfamiliar, and their purpose is unclear. I had speculated in the past that there could be entirely new and unknown versions hidden behind the region change feature, so I guess this speculation was proven correct. I had also speculated that odd integer versions were reserved for developer versions - would this speculation be proven correct too?

Upon resetting the Tamagotchi, instead of being greeted by an egg, the time setting screen is shown instead. Sure enough, the date format that was used by this version was Day / Month, as would be expected after switching to a European ROM version. This screen is followed immediately by the naming screen despite no egg having hatched. After this was an entirely new screen with the options "BOY" and "GIRL". Selecting a gender will finally show you the Tamagotchi you'll be raising:

A Burgertchi

Actually, more accurately, the Burgertchi will raise itself. From this point onwards, the only button which functions is the B button - only the standard Tamagotchi view and the clock screen are accessible. Burgertchi does all the cooking and cleaning by itself - if it's hungry, it eats automatically (aptly, it eats a burger). If it makes a mess, it cleans it up. It flicks between a bunch of different animations, too.

I'm not really totally sure what the purpose of this feature is, or if there's anything else that's unique about this ROM version, but as far as I can tell it's some sort of demo mode. Why Burgertchi? No idea. But I can see this sitting behind a screen in a store, demonstrating what a Tamagotchi looks like without actually requiring constant care and attention.

Hopefully, new discoveries like this will continue being made in the near future! The region change mechanic is a truly interesting one which may reveal entirely new Tamagotchi modes to us.

An update to my previous post: Version 3.0 is actually not just a demo version - it's actually an unreleased Deka version.

The Deka Tamagotchis were originally placed in stores and restaurants across Japan in 2004 and behaved exactly as I described above. The only key difference between these Deka devices and Version 3.0 is that the Deka Tamagotchis were in Japanese, whereas 3.0 is an English translated version, perhaps suggesting there were plans to bring the devices to the west. There was actually a wider range of characters than just Burgertchi, but in order to obtain them you had to solder some connections on the circuit board. Since the V1 uses a different circuit board to the Deka, these connections are not present on the V1 and so a lot of functionality unfortunately cannot be seen.

Deka Tamagotchis also had the ability to connect with other Tamagotchis - simply connecting with the Deka while it's in its idle state will result in the following:

- First, the Tamagotchi moves to the Deka and an animation will play.

- Next, the Tamagotchi will return to its device bringing the Deka character along with them.

- The Deka character will give the Tamagotchi an item before returning to the Deka.

The items received by the Deka characters are mostly food items, often ones not seen anywhere else on the device! There's also a couple items but they don't seem to stay in the player's items list:

- Tamagotchi will give the player a small Tamagotchi device.

- Capsuletchi will sometimes give the player a card that says "Pt" on it and "10p" appears on the screen - perhaps this was part of a cut gotchi points feature on the V1.

So apparently after all these years I'm still learning new things about what the V1 can do! I'll continue to post updates as I learn more information.

In case you're curious where we're up to with ROM versions now...

0W9fSIx.png

There have been quite a few new version discoveries lately! There's a few gaps in the image where I think there's probably more versions, but it seems to be the case that most have been accounted for, now.

There's a few spin-off devices which haven't been tested yet:

- Store Deka Tamas
- Tamasuku 1/2
- TamagoChu
- Tamafure
- Tamajuku
- Tamawalkie

These are the most likely ones to use the same version numbering that the rest of the devices use (maybe with the exception of the Tamawalkie).

If you've any questions about what any of the ROM versions listed above are then I'll be happy to answer.

I'm curious about what the Ver: 8.0 00 and Ver: 9.0 00 are from. Those little cat and mouse guys look pretty angry about it. :lol:

8.0 is a first wave Tamagotchi Friends (haven't seen a second wave ROM test just yet) and 9.0 is from the Dream Town Friends.

I guess the character on the Friends screen is some sort of updated Nyatchi sprite, but I'm not certain. I don't have a clue who the mouse is though!

Thanks very much! :D

I can certainly see the cat being an updated look for Nyatchi, but it was the mouse that got me curious, because I couldn't see any root for them, either. All of the other version-number screens use pre-existing Tamagotchi characters, right? That being so, could the angry mouse* have been a dropped character? :huh:

*Can we call the two Itchytchi and Scratchytchi? :lol:

Either a dropped character or an internally designed one that hasn't been made "public" yet!

What I think is particularly interesting is how each region seems to have one character associated with it - America gets Nyatchi, Europe gets Pochitchi, and by the looks of it the Spanish language versions get Tougyutchi. Assuming the same character is used on the Spanish V4's version number screen, the character would have appeared on the V4 before its international debut on the V4.5. The only version that released in Japan that features a character on the version screen is the V5 Celebrity / Royal Famitama, though I've not seen this ROM version screen yet (it might not even feature a character on it).

The other languages that have been used - Portuguese and Russian - haven't had their characters confirmed yet, either.

Performing the region change procedure on a V1 installed with ROM version 4.1 seems to change it to a new version - 2.3. This isn't a ROM version that had ever been encountered before, so it suggests that there might actually be quite a few more versions to encounter. 2.2, for example, is a gap in the version number list which might be filled some time soon. Perhaps there's even a version 2.4? There's been claims in the past of people having a 2.4, but no pictures have ever proven its existence.

There might even be more ROM versions throughout the rest of the series, too. A4.7 E was only recently discovered after months of assuming the version 4 ended at A4.5 E, with maybe an A4.6 for the Spanish language release. Only time - and more ROM testing - will tell!

Speaking of ROM testing, this entire time it's been understood that ROM tests reset your Tamagotchi's data. This isn't untrue, but most of the test mode that people call the "ROM test" actually has nothing to do with testing the ROM - checking the on-screen pixels and the firmware version come before the screen that says "ROM TEST", and as it turns out, if you never progress to the ROM test screen your data isn't lost.

I'll reiterate that - when entering the test most (e.g. by pressing A, B, C and the Reset button) you're brought through a few screens showing various pixels lighting and dimming. After these screens, the firmware version is shown. On this screen, when a button is pressed, the ROM test begins. If, however, you reach the firmware version screen and press the reset button instead of progressing to the ROM test, your Tamagotchi will restart without any data loss. It's the ROM test part of the process that resets the data.

This is obviously still quite risky because accidentally pressing a button on the firmware screen is enough to reset your data. If you don't believe me when I say that reaching the firmware version screen without ROM testing doesn't reset the data, try it out on a device that you wouldn't mind resetting.

(I'd be tempted to dig out some of my old Tamagotchis to find their firmware versions too, but to be honest, I'd still be a bit concerned about the risk, hahaha)

For those keeping track of where we have to go next, I've compiled a very rough list of the main areas of research when it comes to missing ROM versions. (Of course, we're also researching the versions we do know about to see how they differ from other versions - it turns out the many V1 versions are all very different from one another). Some of the following versions might not actually have a test mode like other devices, but most of them likely do:

V1:
- Spanish language release (this should also give us an indication of other missing versions - for example, if it's 4.4, then there's probably an undiscovered 4.3, too)
- Later EU / AUS V1s (2.3 was recently discovered, so the existence of 2.2 or 2.4 is not totally unreasonable)
- Later US V1s (there might be more undiscovered versions after 4.2)
- Other region change versions (so far, 4.2 has been observed to region change to 3.0, and 4.1 to 2.3 - perhaps there's more region change versions? 4.0 has not been tested yet)

Entama:
- 14.0, 14.2, 14.3, 14.4 (only 14.1 and 14.5 have been observed so far)

V2:
- A.6, A.7 (might be Australian ROM versions)

V3:
- A3 1 (early EU version, potentially could be found through region changing A3 0)
- Spanish language release

V4:
- A4.6 U (late US version)
- Spanish language release

V4.5:
- Spanish language release

V5:
- 28.0, 28.1 (early JP versions)
- Australian versions (might be the same as EU or US though)
- 32.0 (US version)
- 34.0 (EU version)
- Spanish language release

V5.5:
- Japanese version

Music Star:
- 6.0 00 32.0 0 USA (wave 1 US Music Star, though some early US Music Stars mistakenly use the EU ROM)
- Spanish language release

Tama-Go
- Portuguese language release

Friends:
- Wave 2
- Russian language release

Other:
- Store Deka Tamas
- Tamasuku 1/2
- TamagoChu
- Tamafure
- Jukutama
- Tamawalkie

That'd be great, thanks! Since it's a Japanese version the test mode is probably activated with just the B, C and Reset buttons.
