Mega Drive: the first level runs, and the ROM is here
It wasn't supposed to be its turn, but the prototype was sitting right there. The first Mega Drive ROM is downloadable: World 1's first level in a 256KB .gen file that boots in emulators and should boot on flashcarts. Inside is the recipe from the July 9 post: startup, vectors and title screen in 68k assembly, game logic and rendering in C compiled for the 68000. The logic is the same as the prototype, so the gameplay is right; what I can't verify from here is real iron. If you own a Mega Drive and a flashcart, the hardware test is yours: write me what happens. Now back to the C64, which was left holding the joystick.
