Got them! One had some acid inside, got it cleaned up, seems to be working fine now.
So far, from hat i see, is it's where you raise a rex, can fight it, and then after a certain amount of time you can breed them. At least from what i see so far. The instructions are all Japanese, though, and some stuff is Japanese in the game. It's also very musical and has a lot of mini games, even one being the infamous Snake game!
Looks like 3 growth stages, and i see numbers... 3... 6... 9.... so i guess it changes every 3 days maybe? And probably by day 9 you can breed perhaps. not fully sure, can't read it.
The jist of it seems to be a mix of Tamagotchi and Digimon. The breeding of Tamagotchi (I think) plus the fighting of Digimon. I think you can name and choose the gender of the rex as well, but I can't tell, don't quote me on it.
The shells though, ugh... you can tell they're super cheaply made. And the button at the top turns the screen on and off, a nice feature. If left on, it'll eventually turn off, though.
I'll play with these more when I have way more time later on.
In the mean time, would anyone want to see pictures or scans or anything? Maybe scan the instructions so someone can read them if they know Japanese?
