i will do that, i finished the game with amy but didn't collect emeralds, when i tried to replay to collect the emeralds i made that mistake, and now i'm playing with her again, but will take a while, and actually found a funny bug in the previous run:
sorry for the low quality, i take the picture with my phone to send it to whatsapp, i was fighting eggman but i used the hammer to late so he hit me and while falling back, tails grabbed me, resulting in that, tails is froze there and i can move like it should while grabbed by tails, the bug fixed when i jump
and about the slowdown, is random now, when i opened the game today, it was almost without slowdown, since the moment i extract the new version i add the "/MIS1", sometimes work and other times don't, i feel it's my pc
