- PeT mess@utanet.at 2015
-
- Thanks to Deathadder, Judge, Porchy, Klaus Sommer, James Brolly & Brian Provinciano
-
- hopefully my work (reverse engineering, cartridge+bios backup, emulation) will be honored in future
- and my name will not be removed entirely, especially by simple code rewrites of working emulation
-
- flashcard, handheld, programmer, assembler ready to do some test on real hardware
-
- todo:
- !back up gameking3 bios so emulation of gameking3 gets possible; my gameking bios backup solution should work
- (improve emulation)
- (add audio)
-
- use gameking3 cartridge to get illegal cartridge scroller
