I got squished because of missing borders more often on my real Amiga than in emulation
Anyway - those chains could help, I agree.
One small problem, maybe bug, maybe smtg with my equipment: sometimes when I launch Downafall on my real HW it happens, that the game is immediatelly started without pressing of joy button. Not always, but sometimes. I though my son switched autofire on on my joypad before for example, but it is not that case. Anyone else met this?
