Thanks for that. It's either cos i went over 4 mb, or because the save game changed, or perhaps both :) I'll try to fix this with the next release. I don't think it'll quite work on real hardware just yet, so don't worry about that. Just some remaining z80 / 68000 contention to fix.
No problem. In terms of real hardware, I played beta 3 on my Analogue Mega for about 30 minutes last night with no problems. MegaSD menus worked as well.
Awesome. I think you'll enjoy the sound difference between real hardware and emulators. There is a sound bleed or "roll-off" that makes the HW experience pretty unique. Genesis models 1 and 2 have distinct sound profiles from one another.
I made some commercial Genesis games in the 90s, I do seem to remember the sound being different! (but I've not seen a real Genesis in the flesh since then)
