The NeoGeo system is not an emulator itself, but uses the FBNeo emulator. ( Why do we have this? This doesn't work like this for any other system. This section is also confusing, are we no longer defining systems by their folder? Are settings retained from the general mame and fbneo folder?)

You can use this system to visually separate the NeoGeo games from the other arcade games, they will appear as a dedicated system in EmulationStation.

It uses the same romset as the FBNeo emulator.

If you have a special stick like the Happ Rotary Arcade you need to configure both joystick and keyboard at same time:

Dial :   AZERTY keyboard: "^" (between  "P" and "Enter") -- QWERTY keyboard: "[" (leftbracket)
Dial :   AZERTY keyboard: "$" (between "P" and "Enter")  -- QWERTY keyboard: "]" (rightbracket)
Dial 2 : AZERTY keyboard: "*" (between "m" and "Enter")  -- QWERTY keyboard: "/" (slash)
Dial 2 : AZERTY keyboard: "!" (between "m" and Right)    -- QWERTY keyboard: "\" (backslash)

You must launch your game, open the Retroarch menu with Hotkey + B, go to Input Interface and activate the option Simultaneous. Then you can use your joystick and keyboard keys at the same time.

Highscores can be tracked and kept throughthe use of `highscore.dat` which mus be in the right version for each emulator / emulator version, they can be found or must be placed here :

• For FBNeo : /userdata/bios/fbneo
• For mame2003plus : /userdata/saves/mame/mame2003-plus/hi
• For mame2010: /userdata/saves/mame/mame2010/hi
• For mame: see temporary solution in following post

This is the per-game menu for accessing the machine's advanced configuration such as its dip switches, service mode and diagnostic input.

For FB NEO, the default combo is [START] + [L1] + [R1] (old versions ( what older versions? Be specific): Hold [START])

For MAME, the default combo is pushing in [L3] + [R3] (old versions ( what older versions? Be specific. I also don't think this was even removed, ie. you can still press Tab on the keyboard to access the dip switch menu): [Tab] on the keyboard)

For NEOGEO:

• For the default ( factory?) NEOGEO BIOS, the default combo is [START] + [L1] + [R1] (old versions ( what older versions? Be specific): Hold [START])
• For the universal BIOS:
  • At the boot screen, the default combo is holding down + +
  • During gameplay, the default combo is holding down [START] + [SELECT] or holding down [START] + + +

Setup a new shortcut via RetroArch:

[HOTKEY] + → Quick Access → Options → Diagnostic Input

Setup DIP Switches via RetroArch: [HOTKEY] + → Quick Access → Options → Dip Switches
