ok i got all native and alternative emulators to work with all roms in the main menu and with dingux commander too.
FOR future people in the same trouble than me, i will tell you the good path to put your roms, otherwise half the alternative emulators wont even start.
you have to create missing directories
( you have to create roms directory and sub dir.)
Put the good system roms in good directory and all alternatives emulators will work.
EDIT: For get genesis roms working you have to rename your roms to. md. Or you can edit theme. cfg and change. md to. bin or you can add several extension too. The extension name MUST BE in LOWER CASE. except if theme cfg specify extension in Uppercase. anyway try both if it doesnt show your roms.
By the way i got gnuboy4d v1.2 to work and i prefer it, more fast, more stable, better screen quality, but emulator is set for 320x240, so i use full stretched and i got a pretty sweat 320 x 240 scale window. gambatte still dont work
edit: I got dingux 2600, atari to work, works perfect
edit2: PC Engine 1.3.0 beta1 opendingux, Works perfect
edit3: i got OH BOY v20121107 to works, its works perfect, its the best gb emulator for the system.
edit4: i got working another fceu emulators with a beautiful colorful gui, this one works better, faster, than the other fceu and it has frameskip option, but not auto frameskip. i dont remember which one is it when i downloaded it
i hope you are happy to know, i know it will help a lot of newbies with the pap kiii plus.
i just added a entry for gambatte with all instructions and roms path, but it still doesn't work. if someone can help me thanks a lot.
Note: Could someone get the last FCEU nes emu version 29/05/2012 working, it has auto frameskip option and more..
