Alright, my jailbroken ipod recently started being a **** to me and when i would sometimes download stuff like Advanced Wars for gpSiphone ( GBA emulator ) or the ipod touch port of quake it says, "size mismatch" anyone have help on this? If it help those are generally big apps, up 10mb. But i never had problems before. And also! How would i get gpSiphone games? My friend has teh Pokemans and other stuff. I don't feel like SSHing into my ipod but if i have to, i will. thanks in advanced.
Well if they're big apps, and it says 'size mismatch' I have a feeling it may be because you don't have any space left for Cydia. I've noticed in Cydia it says there is like 20MB left for me, yet I know there's a good 4GB left on my iPhone, so it must partition your drive or something. And yes, with gpSPhone games you have to download the GBA ROMs on your computer and SSH them onto your iTouch, I won't go into that though as ROMs are illegal.
SSH your GBA roms to var/mobile/media/ROMs/GBA. However, they are illegal unless you "happen to have the device to convert GBA cartridges to files lying around your house".
