Works great for me. Remember to put your roms in a folder called: "FBANext-ROMS" on the root of your usb device. As for roms i just used roms from the latest mame set. NeoGeo and CPS 1 + 2 works great. Just remember to also put the Neogeo.zip (Bios) in the folder if you use NeoGeo roms.
yeahh ... plz need help to ! i don't have any experience with the FBA Emu.
So i install the pkg i create a dir FBANext-ROMS on a usb then i googled neogeo roms found some roms with the ending *ngp
copy in the FBANext-ROMS folder on usb but i can't start it ... do i need some special roms for FBANext emu ?
neogeo bios i downloaded and also copied into the FBANext-ROMS folder... but always i got the msg... no roms.
I doubt that it'd recognize .ngp files, those are roms from SNK's NeoGeo Pocket system, which was much like the Gameboy. The NeoGeo games this supports are the roms from their MVS and AES games (arcade and console)- they'll probably be in .zip format when you find them, because each game is made up of several files, just like everything that you'd typically play in Mame.
Hope this helps! I'm excited to go play me some Marvel vs. Capcom!
