MAME 2003 Plus notes:

  • Playing Killer Instinct: Create a zip file named kinst-chd.zip that must contain kinst.zip and kinst.chd. Emulatrix will unzip those files in order to run the game (takes several seconds).
  • Saving and loading states: In some games (Killer Instinct, Mortal Kombat 1, 2 and Ultimate) the saving function doesn't work (core issue).

Final Burn Alpha 2012 note:

  • Playing Samurai Shodown III: You must use the samsho3h.zip file.

Emulatrix has mobile compatibility (Android only)
