More complete Galaxy Games emulation: [Luca Elia]
- Created devices for the galaxy games carts (EEPROM + Flash + PIC) and the slot(s) - Removed code patches and emulated the PIC communication and bank switching - Converted the blitter to a device (cesblit.cpp) - moved the Galaxy Games from tmaster.cpp to their own driver (galgames.cpp) Provided the PIC code for all four StarPak cartridges [Keith M. Kolmos] New working machines -------------------- Galaxy Games StarPak 3 [Keith M. Kolmos, Rod_Wod, Sean Sutton, Soren Skou Nielsen, Russell Howard, Francis Ramirez, Tourniquet, BrianT, coolmod, Smitdogg, The Dumping Union, Luca Elia]
