Hacks arent ready for prime time on this system, imo. Thanks for your sacrifice.
It would appear as if ! Sadly
I'm unsure if my issue is a Hackchi issue or a Retroarch issue to be honest.
I did some testing the other day.
I'm currently using the Sega Genesis classic/mini to play GENESIS, MASTER SYSTEM, and TG16 games.
I got everything set up to display in full/widescreen with scanlines (which is the desired effect I wanted).
Games will launch by pressing both "A" or "START."
My notes are @ home, so I'm going off memory here.
When playing Master System and TG16 simply pressing down on the stock gamepad dumps you to the game select menu.
I've still be unable to solve this issue. "START" will dump to the Retroarch menu which is fine, it's the quitting the game that sucks !
