Player 4 Trouble in Mame 2003 Plus

redmagehat

I’m struggling to get player 4 to work within the Mame 2003 Plus libretro core. Here’s my setup:

Latest Batocera version
Arcade cabinet using DragonRise USB encoders tied to arcade joysticks/buttons
Running on 2014 Mac mini, installed to internal SSD

Player 4’s controls are working great within the Batocera ES interface - it’s registering buttons and I can launch games and everything. I can also manually reroute Player 1 to the Player 4 joystick/buttons through the RetroArch menu in other cores (NES, SNES, etc.)

However, when I’m trying to play a 4-player Mame title like TMNT or Simpsons, only Player 1-3 controls will work. I’ve gone into both the RetroArch and the Mame config menus and everything seems to be mapped correctly.

Any ideas? Really wanting to get that fourth player rolling =)

Figured this out. Even though the mappings in the MAME internal menu were correct, I had to clear them out and then re-establish them, and then they began registering correctly in RetroArch. Just in case someone else has this same problem.
