Wow, rolling thunder, did not expect that!
can confirm it boots on real hardware, tested on model 1 NTSC genesis
game plays great, first level track seems to have a little skip issue here and there, please remove the black bar at the bottom and top of the hud just like the arcade, i think it will look a lot better, i think the intro to the game is missing when starting arcade mode, in home mode there is no way to set controls differently, i would also make B shoot and C jump instead, when switching between each character on the select your agent screen, the image goes black for a second switching back and forth,
I would also add an attract mode to all of your ports, so far this is great tho, ill keep updating this comment, the more i find, i would also add more tags to the itch.io page for side arms and this, it will help users find your projects easier
thank you for putting out another genesis port
