Im trying to get neogeo and MAME emulators to run. Im using a 32 gb sdhc card. the snes emulator is working just fine. Both the neogeo and mame emulators freeze as soon as the emulators load and show the list of roms. I added the neogeo bios files into the roms folder and only used verified working mame roms with mame. I know im doing something wrong cause this doesnt seem like a common issue and both emulators freeze at the same screen essentially.

Just uploaded a couple pics of what my SD looks like.
