My Mega Drive ROM v1.01 was compiled sometime in February 2016. I was supposed to write something about this over five years ago but it apparently got away from me.

Version 1.00 (above) is pretty simple. I edited the sample source code and compiled the ROM under Ubuntu if I remember correctly. Here is the source and my compiled ROMs. Version 1.01 gets a little more complicated.

I can’t quite remember what I compiled it with though. Wait! Ah yes, it must have been SGDK by Stephane Dallongeville. The source in the ZIP uses its genesis.h header and controller functions, so that looks like a pretty good clue!

They also have a Patreon if you want to support them. I’m glad to see the project is still being worked on after all this time. Maybe I’ll revisit it sometime in the future, regardless - Thanks Stephane!
