Problem with Playstation emu and controller detection

Libretro Lakka
#1

Hello, All! First let me say how much I appreciate all the hard work that went into developing Lakka into what it is, and in to fixing all the little quirks :slight_smile: This is my first post, and i do apologize in advance if this has been solved somewhere else, but from preliminary searches, nothing came up that answered my question.

I’m using Lakka OS on a dell Latitute 6430, so not the application for Windows, rather the linux GUI, in case this info is important. Platform has plenty of power and resources to run all the emulation, only one i haven’t tried, yet, is MAME (as i can’t find viable BIOS files lol, but that’s another issue…).

My issue is this: on genesis and SNES emulation, after i go through the lakka controller config, i can start a ROM and play no problem; all buttons are recognized in both situation. When I start a playstation game (scan finds the ROMs, so BIOS are working, i think…!), i get a moment of a black screen, looks like the emu starts, then briefly a message on the bottom-left corner saying “gameflow” (name of controller) not configured", and i get the main lakka home screen again.

Are there extra configs that need to be done for the PSX emulator to “see” the USB controller?

Any help will be highly appreciated!

The controller message is likely a red herring. Your issue is most likely a BIOS problem, statistically speaking. To check if your BIOS images are being detected properly, load up the core but no content and then go to information > core information and it will tell you which BIOS files are being found. If they’re all there, the next thing to check is your ROM images. Mednafen-psx only loads cue sheets (i.e., from bin/cue pairs), so make sure you’re pointing to the cue and not the bin, and then open the cue sheet in a text editor and make sure it’s pointing to the correct bin file and that the filename it points to is case-sensitive (many cue sheets were created on and for Windows, which is case-insensitive).

OK! i’ll look into that as soon as i can. I honestly didn’t’ bother checking if the core was configured properly because as soon as i loaded the presumably correct BIOS, ROMs popped up after a folder scan…so i was ecstatic, as that never happened lol

I had decided to reset retroarch as much as i knew how, without a full reinstall, and i was able to play PSX (and MAME/arcade) games by stopping retroarch service on ssh console, resetting retroarch.cfg, restarting retroarch service, plugged controller back in. Most buttons functioned! I still need to load content from menu, instead of using the “pretty” playlists, but i’ll live… :slight_smile:
