If you’re trying to compile UAE – The UAE Amiga Emulator on Red Hat 8, or any other modern Unix system you may encounter the following bug:
./tools/cpuopti <cputmp.s >cpufast.s
Corrupted assembly file!
This is easily fixed by copying the cputmp.s file over cpufast.s:
cd src; cp -f cputmp.s cpufast.s; cd ..
I’m also looking at Xfellow but SDL just crashed when I tried to run it so it might take some tinkering to get it to work on my system.
