Description: With this tool you'll be able to make independent retroarch cias for your favorite Neo-Geo games using the Final Burn Alpha 2012 NeoGeo core without having to install retroarch or anything besides the generated cia. Usage: It's pretty self explanatory, there is only one thing that isn't quite clear: You need to copy the Neo-Geo bios (named "neogeo.zip") in the same folder as this program. The program will detect if the bios is usable and wont let you proceed if the bios is missing or incompatible. If the resulting cia doesn't boot (boots and kicks you out to the 3ds menu without warning) is most likely due to an incompatible romset, you can test your roms with the pc version of Final Burn Alpha or Retroarch before creating the cia to make sure that it will work. Big games (like Metal Slug 3, SVC Chaos and most of the King of Fighters series) will take a while to boot, just wait a minute and you'll be greeted with the Neo-Geo bios like usual. Key mapping: The buttons are assigned as follow: Neo-Geo A = 3DS B Neo-Geo B = 3DS A Neo-Geo C = 3DS Y Neo-Geo D = 3DS X Neo-Geo Start = 3DS Start Neo-Geo Coin/Select = 3DS Select Turbo button: As of version 1.5.1 a turbo button has been added. This button has to be manually enabled by giving it a key map from the button remapping option. It works like a shift button, any other button that you press while holding the turbo button will rapid fire. Uni-bios usage instructions: Warning: Spoilers inside! First, to navigate this menus you have to press A (B in 3DS buttons) to accept/change settings, B (A in 3DS buttons) to change setting in the opposite direction and C (Y in 3DS buttons) to go back. To access the uni-bios menus you have to press A+B+C (B+A+Y in 3DS buttons) at the first screen (illustrated below). The very first option is to configure the region and mode at what the game will run. To access the dip switches you have to press B+C+D (A+Y+X in 3DS buttons) at the same screen as before. Then go to the third option. And then the second option. You can change the game setting from there like the difficulty, timer, blood and such (most games will let you change difficulty and time from the game menu of you choose to run the game in console mode). You can also access an in-game menu that contain cheats if you press Start+Select while playing.
