Don't worry about the 24-bit pbms, I can deal with those. The credit art illustrations should be easy enough since they are placed in a folder outside the executable in the ports. As for asm hacks the problem with them is that the executables and instruction sets are different for every port. But yeah, asm hacks are my main concern.
