Emulators: lr-fbneo, lr-fbalpha2012, PiFBA, GnGeo-Pi

Refer to the main FinalBurn Neo page for general information on all FinalBurn emulators or the direct links above for in-depth infomation on lr-fbneo, lr-fbalpha2012, or PiFBA. In-depth information on GnGeo-Pi can be found below, which is also linked directly above.

lr-fbneo is the prefered Pi 3/Pi 2 Neo Geo emulator due to its accuracy.

lr-fbalpha2012 is useful for any games that may be running slow in the latest version of lr-fbneo for a Pi 3/Pi 2, and if used exclusively instead of lr-fbneo will allow you to do full system updates without worrying about needing to update your ROM Set, but comes at the cost of inaccuracy such as games having audio issues across the entire library and other issues that have been fixed in the latest version of lr-fbalpha.

PiFBA is recommended for those on a Pi 0 or Pi 1.

ROMS

Accepted File Extensions: .7z .zip

Place Neo Geo ROMs in:

BIOS

Neo Geo ROMs require a neogeo.zip BIOS file with the exact same MAME or FB Neo version as the emulator you select. Place the correct neogeo.zip with your ROMs in:

Instructions on how to install the Neo Geo Unibios on lr-neo can be found here: lr-fbalpha Neo Geo Bios. The Unibios can be used as documented on the official page at http://unibios.free.fr/howitworks.html.

On the Unibios boot screen
- Neo Geo A+B+C (RetroPad B+A+Y) for BIOS Menu
- Neo Geo B+C+D (RetroPad A+Y+X) for Test Menu
At any time
- Neo Geo Start+A+B+C (RetroPad Start+B+A+Y) for In-Game Menu

The menus allow you to change various settings like region, dip switch settings for gameplay options like difficulty or blood, and coin or free play settings. Unibios settings will persist after quitting FBA, launching another Neo Geo game, or rebooting RetroPie.

Controls

You will configure controls differently depending on which emulator you use:

lr-fbneo and lr-fbalpha2012

lr-fbneo and lr-fbalpha2012 utilise RetroArch configs. Add custom RetroArch controls to the retroarch.cfg file in:

For more information on custom RetroArch controls see: RetroArch Configuration

PiFBA

PiFBA controls are located in:

As there is no menu to configure controllers with PiFBA, like there is with Mame4all, you'll have to edit the aforementioned file manually.

Example fba2x.cfg:

GnGeo-Pi

MAME Version: 0.138 (May 2010)
Romsets emulated: 203
GnGeo-Pi DAT File: pandora_gngeo_084_dat.zip
GnGeo-Pi Filtered DAT File: pandora_gngeo_084_filtered.zipAll clones non-workingmahjongquiz removed
Romsets emulated: 128

GnGeo-Pi Compatibility List feel free to contribute to the list.

As a caveat, if you're using _gngeo-pi__, the ROMs you have must match the file in gngeo_data.zip located at:

You can only play roms that have the same name as these .drv files, e.g. mslug2.zip (rom) and mslug2.drv (data). If the names of these files don't match, GnGeo-Pi will crash. (see the list at the bottom of this page for compatible ROMs)

GnGeo-Pi Controls

Once you've started GnGeo-Pi at least once a file called gngeorc will be created in:

List of GnGeo-Pi ROMS:

Please check FinalBurn-Neo for for basic information about controls and managing ROMs - this page is for specific information about the lr-fbneo emulator's features.

lr-fbneo is a popular choice for the Raspberry Pi 2 and up, as it supports the latest FBNeo romset (v0.2.97.44), and a broad set of features. FBNeo also should always outperform MAME in the games they both support, as it is tailored for speed, rather than accuracy. Also, it is a libretro core, so enjoys all the benefits of that: centralised controller configurations, many customisation options, netplay, shader/overlay support, etc.

System menu

By default, if you hold the Start button for a few seconds, the ROM system menu appears. Here you can set various game options, typically including 'Free Play' modes, regional settings, etc. Settings are saved in .fs files in the ROMS directory for the system in use, and are loaded automatically on next use.

Dipswitches

lr-fbneo exposes all the dipswitch options of any given game as Core Options. See Setting Core Options. The dipswitches available will vary from game-to-game.

High scores

lr-fbneo will attempt to keep a permanent record of any high scores you set, but some games will not save these by default. There is a supplementary file that is automatically installed to your Pi that will enable high score saving for more games, called hiscore.dat. This file is the same as that from http://highscore.mameworld.info/ (labeled 'old format hiscore.dat (pre mame v0174)'). It is located in:

When high scores are saved, they are kept in the current rom directory as gamename.hi files.

Arcade layouts

lr-fbneo has been configured to use the SNES layout in six-button fighting games. That is:

So arcade stick should be setup accordingly.

Samples

Neo Geo Bios For Retroarch

Some sound effects in a few older (typically pre-1986) arcade games are difficult/impossible to emulate. Instead, audio clips of these effects can be downloaded and automatically played at the appropriate times. FBNeo additionally supports the use of some higher quality samples such as the CD audio rips from the console version of Donpachi. Samples are often included in a romset, or you can find some at http://www.progettosnaps.net/samples/. Place them into:

Neo Geo UNIBIOS

For Neo Geo games, you may want to use the UNIVERSE BIOS/UNIBIOS - an advanced Neo Geo bios that allows region selection, cheats, dip-switch control, and more. To active, change the Core Option for Neo Geo mode to UNIBIOS. See Setting Core Options.

Note that this will automatically use the latest version of the UNIBIOS avaialble in your neogeo.zip. If
