Ok I figured this out, you need to choose the mednafen pce fast core and in the RetroArch menu go to Options-Core Input Remapping Option and assign one of your buttons to User 1 Mode Switch. I chose my select button. When in game, pressing select will enable a 6 or 2 button pad and a message will appear in yellow text on screen to show which is active each time a mode switch is made. Hope this is helpful for someone :)

It will also work if you choose Genplus GX as the emulator instead of Picodrive. That way it does not have to be in a .bin file and the music files can be separate.

[charco]

I’ll try that config. I have another SD card so I’ll write the Beta 4 image to it and see what happens. Thanks for all your help.

[charco]

Sure here’s what I have:

`pifba=”/opt/retropie/emulators/pifba/fba2x %ROM%”
default=”lr-fba”
lr-fba=”/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fba/fb_alpha_libretro.so –config /opt/retropie/configs/fba/retroarch.cfg %ROM%”

[charco]

Well that was easy! Added Neo Geo Pocket Color in 2 minutes!

[charco]

Cool, thanks!

[charco]

When yoy say updaye my setup script, does that mean I am upgraded tp Beta 4?

[charco]

I have v3.0 Beta 2, can I obtain the Neo Geo Pocket, Virtual Boy, and Wonderswan cores using the Setup Script? Does this create the system rom folders and add simple themes for each system?

[charco]

Not sure about FDS but for Super CD games place syscard3.pce and SYSCARD3.pce in both your BIOS folder and your roms folder. I am not sure which one it is that works, but one of them does anyway. I can only get bin + cue games to run.

[charco]

I just checked before you posted and I am not getting the yellow text on booting up a game as I do on all the other RA emulators, even though the controls work in game and in the RGUI input settings it has the USB,2-axis8-buttongamepad listed as the device type.

Yes, this is a RetroPie 3.0 beta 2 image downloaded from this site.

EDIT: Changed fba RetroArch config text to: # include “/opt/retropie/configs/all/retroarch.cfg” and unfortunately that did not do anything either.

So, we can see that as the yellow text is not appearing on start up it is not finding the gamepad config file that the other RetroArch emulators use. Is it using some other file?

Have we exhausted all possibilities at this stage and should an issue be opened on github for RetroPie Setup or is this an upstream issue?

I wonder how yours is finding the correct gamepad config. These roms are all running on lr-fba using the FB Alpha v0.2.97.30 romset

[charco]

Tried the alt thing, no change. Select + Start works perfectly in the other RetroArch emulators to exit. Holding L (button 4) and pressing start does nothing in lr-fba still. I can only exit by pressing the Esc key on my connected keyboard, if I unplug the keyboard, there is no way to exit and the PI 2 must be powered off to exit.

[charco]

I’ll try changing that to “alt”

Here is my USB gamepad config. This has never been altered.

[charco]

Here it is.

[charco]

It still retrieves the first 2 gamepad config files posted above.

I can confirm that my fba system retroarch config is exactly as you have posted above.

[charco]

I deleted the older config file but the issue persists.

[charco]

Yes, I mean lr-fba Neo Geo from the Neo Geo menu as opposed to FBA and not with PiFBA.

I typed in the above command and it lists 3 config files as follows:

/opt/retropie/emulators/retroarch/configs/USB,2-axis8-buttongamepad.cfg:1:input_device = "USB,2-axis 8-button gamepad  "

/opt/retropie/emulators/retroarch/configs/iBuffalo_ClassicUsb_Gamepad.cfg:1:input_device = "USB,2-axis 8-button gamepad"

/opt/retropie/emulators/retroarch/configs/USB,2-axis_8-button_gamepad.cfg:1:input_device = "USB,2-axis 8-button gamepad  "

[charco]

Did that, no change. I really have no idea. Keyboard must be plugged in at all times or the only way to exit Neo Geo is to pull out the power chord.

Floob uploaded a video that will help you solve this issue here:

Beta 4 has been released since and this issue has been resolved, perhaps you should just install that if you haven’t reconfigured too many things on your Beta 3 install yet?

[charco]

Glad it’s working!

[charco]

Sweet, thank you. I’ll try this tomorrow, might finally be able to unplug the keyboard :)

[charco]

Will removing the hotkey and exit buttons not cause an issue with all my other RetroArch emulators though?

[charco]

Thanks, here are my main RetroArch and system RetroArch config for FBA. Where can I find the auto controller config? I have the same iBuffalo SNES pad as you have I think going by your videos (which are great by the way).

[charco]

Thanks!

[charco]

I have edited that and ensure that input_exit_emulator_btn = “7” for my Start button. Still doesn’t do anything in lr-fba unfortunately.

[charco]

How do you change file permissions to “pi”?

[charco]

No it is definitely not the bios or the images as they are tested with Libretro PCE on 2 other playforms and work flawlessly.

[charco]

I can’t seem to sort this, perhaps it’s something that can be fixed upstream for the next release as it’s too complicated for me.

[charco]

I tried that but it still doesn’t run.

[charco]

You need to place the bios file in the BIOS folder.

Thanks for your help guys, I downloaded GIMP and took a screenshot using RetroArch Windows to create a custom PC Engine theme :)

I used 15 Gaussian blur, might increase it to 18 as it might not be blurry enough, very happy it worked though!

[charco]

Now choose Quit RetrArch to save the settings

[charco]

Make sure Configuration Save On Exit is set to On.

[charco]

Sweet, I will download GIMP so :) Thanks!

[charco]

Thanks man, can you easily create the blur effect on an image using Inkscape?

[charco]

Have you tried going to raspi-config advanced options and chosen “Force audio out through hdmi or 3.5mm jack”
