While digging through floppy archives i remembered that long, long time ago i was so impressed with the Golden Axe, that i tried to run it on my XT and experience was awful.
My XT had no turbo mode, so it was absolutely not playable. I managed to find "problematic" part - it was a timer routine running at 7Khz. It had an internal 8 cycle counter so i removed counter and reduced frequency 8 times as well and removed sound. It started to run much better.
I have recreated that hack now, and it's again somewhat playable at 4.7Mhz and runs absolutely nice at 8Mhz / CGA. if anyone interested - i can provide executable.
