  • Pierpaolo Prazzoli made several improvements and game additions to the Nintendo VS and Playchoice drivers.
  • Acho A. Tang contributed several fixes for Super Real Darwin

  • Bryan McPhail fixed some bugs in the I86/NEC CPU emulation. This includes raster effect problems in Geostorm and the 99 credits bug in Lethal Thunder.
