Alright, so I searched around for a while and have no answer...
But I'm using No$GBA2.6a and No$Zoomer 2.3.0.2, and the game freezes on the first enemy encounter. If I turn on EXTRA 5 on No$Zoomer, I'm stuck at a black screen instead. I've used the Rudolph's Child Play Patch on the rom, but to no avail.
For those who have it working somehow, is it okay if you detail how your No$Zoomer folders and stuff are set up? I remember having a similar "AP" problem with SupaRobo Gakuen and downloading someone else's folder setup actually worked.
Edit: Also I'm aware some of you are probably using Flash-carts and the like, so I'm probably at a loss either way.
