differences between regions

I know that Bandai produces the tamagotchi series under Bandai Japan, Bandai America, Bandai Europe (known as UK tamas), and Bandai Asia (known as Chinese/HK tamas).

Although Japanese tamas are easy to distinguish from the rest, I find it hard to part the other three.

From what I know, the English releases are...

+JP

-p1

+US

-p1, p2, angel, ocean, mini

-v1, v2, v3, v4, v4.5, v5, v5.5, v6, tamago

+UK

-p1, p2, angel

-v1, v2, v3, v4, v4.5, v5, v5.5, v6, tamago

+CH/HK (includes Australia/Oceania)

-p1, p2, mini

-v1, v2, v3, v4, v4.5, v5, v5.5, v6, tamago

-tamawalkie, iDL

Is this right? Is there any more tamas that I have not included?

and the main question is..

Is there differences in tamas between non-Japanese releases? I mean, between the US version, UK version, or the Australian/Chinese versions. And in the programming, not the designs or shells.

Err... like... is there a difference in programming between the US v4 and UK v4? US tama-go and Chinese tama-go? US v2, HK v2, UK v2? and so on.

I know my questions sound weird but I'm willing to explain more.

plz tell me anything you know about these differences.

Even the smallest difference, like one character or so is veeerrrrrrrrrrrrrrry important to me.

There's not much really.

The UK has some different words from the US due to the language. Both are English but theirs the UK/British English right?

Other than that, I don't think there are any difference in the programming itself.

Well I do know that UK tamagotchi V2 V3 cannot be debugged.

That's a difference.

The date format may be different between regions: day/month vs month/day.
