A problem with Older Models.

This isn't a complaint more than a question. I've noticed that with my project Elaysia It works fine with my New 2DS Xl. But with my girlfriends 3Ds (First Model) It has a glitch with textures on @A1 @Memoriam and @A5. But there is nothing different in the coding between hers and my version of Elaysia. I just want to know why. :) (If it is obvious, the i'm clueless.)

The old 3DS is slower than the new one. If your game runs slower on it then there's probably some major problem, since if the o3DS can't handle it, that means that the new one can only BARELY run it.

@12me21 Its not running slow it's just texture glitches in three places. The other 40ish places run fine.
