I want to very first say, I like the mini and all the other games look to run completely. This isnt a complaint, I want to know if I am crazy.
I am fresh off playing it on an actual Genesis, the issue is that on the mini the jump inputs really feel extremely lagged compared to the original cartridge.
I can do a 20 second Emerald Hill Zone 1 on cartridge but on the mini the precision handling of Sonic just isnt there.
Sonic 1 feels ideal extra or significantly less I will say.
