Activate the working mamemess core in Android

on latest Retroarch the mamemess core works and I confirmed with the GamePark GP32 platform. However the exported GP32 platform fails to remember the mamemess_libretro core and get stuck on the launching screen after it opens Retroarch without launching the game.

• My process to have the GP32 running on retroarch android is the same for mame (in Retroach first then on launchbox):

• use mame softlist GP32 roms.

• put them in Games/gp32 (important to be “gp32”

• Add the bios gp32.zip to the folder

• Add Retroarch playlist by manual import using the mame hash gp32.xml in system/mame/hash folder and disable scan inside zips.

• set core to mamemess.
  set core cpu to 30% or less for full speed. 100% runs slow, no idea why on rp5.

• On Launchbox pc I use the thirdparty import mame software list plugin to export the initial platform .xml and images then replace in the xml:

  • <DefaultEmulatorCore>mamemess_libretro_android.so</DefaultEmulatorCore>
    and remove each rom <emulator> Line to match the native imported platforms.

    
    I attached the video on Retroid pocket 5 for more details.
    I guess it should work for most mess platforms
    Cheers.
