rocketfan Posted September 23, 2022 Author Share Posted September 23, 2022 @pimpmaul69 Lynx is a standard core that we got from the folks at Libretro. Unfortunately they stopping building/adding cores that work for our architecture but most of the cores used on these devices came from when there were building them a year or two ago. All those just support standard Retroarch keymapping. You can see what handy_libretro.so has documented about typical inputs here: https://docs.libretro.com/library/handy/ retroplayer.l allow button mapping, which is called keymapping in the retroplayer.ini file. Some info taken straight from the instruction_manual.txt file: ========== #RETRO B Y SLT STA UP DWN LEFT RGT A X L R L2 R2 L3 R3 #INDEX 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Here is an example of a key mapping entry. [KeyMappingUser] MarioBros.nesl=0, 1, 9, 8, 10, 11 Note: The special .nesl extension that is used so that the ROM is ran using the retroplayer L and buttons can be changed. In this case the A and B buttons were swapped so that this previously unplayable one-button game is now playable. ============== Retroplayer.l came from the legends flashback and the intent there with the button mapping is to let you assign x,y,z,a,b,c on a 6 button Megadrive pad. So we are just abusing that to allow cores to be used with the Atari joysticks. For the player 1 joystick I think you could only map the first button (first position) and the select button (fourth position) - to something the core would recognize. The other positions (AFAIK) do nothing - like start is just literally start in the core, but feel free to experiment. So, for lynx in your retroplayer.ini you have (for example): BatmanReturns(USA,Europe).lnx=0, 1, 9, 8, 10, 11 Looking at the first position you have 0, so look that up in the table above - 0 corresponds to the B input in retroarch, so that is an attempt to make the fire button act as the B button. Looking at the fourth position you have 8, which corresponds to A in the table above, so select ought to act like the A button. Again, the rest are don't cares, AFAIK. 1 Quote Link to comment Share on other sites More sharing options...
