Sonic the Hedgehog (Stealth's GBA port)
Stealth ported Sonic 1 to the Gameboy Advance in early 2007 based on the original Sega Genesis source code.
It clearly shows that Sonic 1 can work properly on the Gameboy Advance.
On this port only Green Hill is fully playable and an unfinished act 1 of Labyrinth can be played by holding the L button while pressing START on the title screen. Oh! and the debug mode can be activated on any level with the R button.
