So, you got Launchbox + LEDBlinky + MAME working?
I have tried all the frontends and I can only get MAME + LEDBlinky working with MALA. I use RL for every other emu launched in MALA
Suggestion regarding the question about using other emulators with LEDBlinky:
I create a new rocketlauncher.exe for each emu simply by copying the original rocketauncher.exe and renaming to "rocketlauncher-emuname.exe"
Then, the emulator executable (that MALA looks for) for Sega Genesis, for example, is "rocketlaunchersegagenesis.exe" This allows me to the create a default set of control lights for Sega Genesis in the LEDBlinky controls editor.
The issue, I think, is that LEDBlinky can only monitor one frontend at a time and one emu at a time. So it cannot light MALA and then light RL (as a frontend). It can light MALA then RL (as an emulator call). I just could never get LB to light much of anything in Gameex or HS or RetroFE.
