Awesome, thank you very very much! That will take a while to digest, but at least it gives me plenty to look at
Back in DSF-land the code from 14e4 to 1574 calculates the DISDL/DIPAN values (in manatee.drv 2.50, taken from kingshriek's full Skies of Arcadia rip). I don't see anything wrong ARM-emulation-wise there, but I'll have to see if I can rig it to use VBA's ARM or something instead so I can have comparison values
