jadawan, could you do me a favor and e-mail me at ?

[Idris_Arslanian]

1: Yes, exactly.
2: Yes, exactly!
3: I tried to use as many of the default buttons on the XArcade as possible.
4: Defaults were fine.

[Idris_Arslanian]

Yup, I couldn’t get it working when I plugged in a USB keyboard either. I needed to do it through the PS2 connection on the XArcade. Then it’s a matter of making your mappings match with the available keys in inputcommon.c (see above post). I had to program the XArcade stick as well because I couldn’t figure out what the mappings were for a couple of the keys (I believe “]” in particular). It just takes some fiddling. Good Luck!

[Idris_Arslanian]

Yup, sure did. I’m going to need a bit more info from you though if I’m to be of help. How does your RetroPie.cfg look? How did you hook up your XArcade? How is the keyboard hooked up?

[Idris_Arslanian]

Yes, the 512 model B is fully supported.

I used this tutorial with great success:

http://dhruvgairola.blogspot.com/2012/10/raspberry-pi-with-neogeo.html

Please note that for my installation, installing ZLIB was NOT OPTIONAL. W/R/T the BIOS files, they need to be unzipped inside /usr/local/share/gngeo You will need all of the following BIOS files:

gneogeo.zip
neogeo_old.zip
neogeo.zip
uni-bios.zip

After you get everything in place, you may also need to modify how the es_systems.cfg executes the emulator. It helps to manually run the command from the command line instead of through EmulationStation in order to debug.

[Idris_Arslanian]

I had the same issue. Solved it by going into the EmulationStation es_systems.cfg and editing the COMMAND portion for Master System, removing the “-tv” (option that forces the emulator into old-school tube mode).

[Idris_Arslanian]

If you are using the default MAME emulator through emulationstation the config file is in “/home/pi/RetroPie/configs/all/retroarch.cfg

(see command in es_systems.cfg:
COMMAND=retroarch -L /home/pi/RetroPie/emulatorcores/imame4all-libretro/libretro.so –config /home/pi/RetroPie/configs/all/retroarch.cfg –appendconfig /home/pi/RetroPie/configs/mame/retroarch.cfg %ROM%
)

[Idris_Arslanian]

I can’t get anything to run reasonably without overclocking to at least 900mhz. If you go above that though, a heatsink and small fan would be advisable.

[Idris_Arslanian]

What does your DGENRC file look like? Also please include the DGEN section from your .emulationstation/es_systems.cfg file.

Things to check:
SD Card: Has it been tried before or verified?
http://elinux.org/RPi_SD_cards

Keyboard: Try plugging in another keyboard to see if something may be stuck

Power Supply: RasPi can be touchy with power supplies.
http://www.raspberrypi.org/phpBB3/viewtopic.php?f=29&t=42033

Graphics Memory Split: What are you set at?

Command line attempts: Go into the EmulationStation systems config and try to manually input the commands to start a ROM through it’s specific emulator.

EG: The command line syntax I am attempting from the Osmose directory is:
./osmose /home/pi/RetroPie/roms/mastersystem/A.sms -fs (where A.sms is the ROM name… it may help to rename the ROM to something w/o spaces or special characters)

[Idris_Arslanian]

Hmm, I was able to get Osmose to run when I took out the “-tv” from the emulationstation/command line command. However, that would cause the ROMS to run in a windowed mode, even with the “-fs”.

[Idris_Arslanian]

You forgot the monitor! Preferably one with HDMI and internal speakers.

[Idris_Arslanian]

I believe you just have to comment out (# at beginning of line) the emulators you do not want in the emulationstation config file (es_systems.cfg).

FYI to anyone who stumbles upon this thread. You can get most of the available keycodes from the inputcommon.c file. I got a good response here: https://github.com/Themaister/RetroArch/blob/master/input/input_common.c#L613

Note, you need to use the first portion (quoted).

Well, I snagged a PS2 keyboard so I could hook up the XArcade and keyboard jointly so the Pi would recognize them both as the same keyboard input. However, I am having trouble remapping the buttons in the RetroPie.cfg. I have the following in the file, but it is not recognizing the reconfigured buttons. I have no .cfg files in any of the emulator specific configuration folders:

home/pi/RetroPie/configs/all/RetroPie.cfg

# Keyboard input. Will recognize normal keypresses and special keys like “left”, “right”, and so on.
# Keyboard input, Joypad and Joyaxis will all obey the “nul” bind, which disables the bind completely,
# rather than relying on a default.
input_player1_a = “5”
input_player1_b = “c”
input_player1_y = “lshift”
input_player1_x = “z”
input_player1_start = “1”
input_player1_select = “3”
input_player1_l = “lctrl”
input_player1_r = “lalt”
input_player1_left = “4”
input_player1_right = “6”
input_player1_up = “8”
input_player1_down = “2”

input_player2_a = “e”
input_player2_b = “w”
input_player2_y = “]”
input_player2_x = “6”
input_player2_start = “2”
input_player2_select = “4”
input_player2_l = “a”
input_player2_r = “s”
input_player2_left = “d”
input_player2_right = “g”
input_player2_up = “r”
input_player2_down = “f”
# input_player1_l2 =
# input_player1_r2 =
# input_player1_l3 =
# input_player1_r3 =
