I was careful. ^^~
Just got it finished. The battery seems fine. It loads all my games, but it's very inconsistent. I'll try once and it freezes, I'll try a second time and it will say "analyzing rom" then "loading to ram" then give me a white screen, then I'll try a third time and it works.
My Mario Advance 4 is glitching up at the the intro, but I think I remember reading somewhere that it needs to be patched in some way.
Rudolph's Back up tool is recognizing it, but it always freezes after it tells me what cart I put in to copy. "Reading of file list" and such.
The ram and rumble functions still are not being recognized. I figure it's just because I was sneak-shipped a 3-in-1+.
I don't mind, though. I'm just glad I can (sometimes) play games. I can wait for new releases o' stuff for the rest.
