Wario Land 3 is a hack of Puggsy for the Sega Mega Drive/Genesis. When played on an emulator, the game will often throw up an error message and refuse to let you play past Stage 5; this is because the anti-piracy SRAM check from Puggsy is intact (Puggsy does not have SRAM, but many emulators will create an SRAM file for the game anyway).[1] This error will not show up on real hardware.
Differences
The only changes are Puggsy's sprite, and the title screen.
