The tricky problem of removing screws from older versions of tamagotchis has been discussed a few times recently on these forums
This is a link to a post by binary which might be useful:

although I would recommend that you read through the whole topic as it's gives a lot of background info and ideas for removing tight or stuck screws from an older tama.
Good Luck.
Yeah thanks, the first thing I did when the screwdriver wasn't working was do a search here for "screw" and I read through every single topic about it.
It sounds like all I need is a JIS #0 Screwdriver, I'm going to see if they have them at Lowes (I doubt it.)
Otherwise I will buy these ones

EDIT: Ok I went to Lowes and got the screwdriver they recommended for me, but it doesn't work either, so I just ordered that set of JIS Screwdrivers off of the website.
Anyways I'm turning Mothra on now, the Egg popped up and it looks like the batteries are working despite being over ten years old.
EDIT #2: Ok so I set the time and everything, and the twin girl Eliases/Cosmos (I think in the Rebirth of Mothra movies that this one was made to promote they were called Elias.) came out dancing, and singing around the Egg, until it hatched into the smallest Larva with no mandibles, I quickly fed it until it was full, and played some games with it, after that I kept checking to make sure that its hearts didn't empty, and fed it, and played with it when they did, the little baby had just been born and it was already five tons!
After awhile it suddenly made a weird beeping noise and I saw it was taking a nap, TO MY HORROR IT HAD A POOP NEXT TO IT!!! I hope this doesn't affect it too badly, I didn't even know it had pooped! anyways I cleaned that up right after it woke up a few minutes later.
I went to have a poop myself, and I took it in there with me, while I was doing my business it made some weird noises and turned into the next stage up, so now it has a longer body, a bigger rounder head, and it finally got its mandibles! they really open wide when it eats!
I am periodically checking it to see if any hearts are empty, but none have gotten empty so far, the little darling is ten tons now!
Anyways I'm glad I know Katakana, and Hiragana so I can read all the words in the menus (For example the discipline meter says "Seigi" which means like justice or something like that.)
Something I forgot to mention is that I really like how the casing for the Mothra Tamagotchi looks, it resembles Mothra's egg in the movies! with similar stripes and everything! although not as detailed.
Edit #3 (Sorry!): Ok it went to bed at 8:00pm as I was expecting.
