[C decompilation] [th02] Code segment #2 of all three executables Only one code segment left in both OP and FUUIN! its-happening.gif Yeah, that commit is way larger than I'm comfortable with, but none of these functions is particularly large or difficult to decompile (with the exception of graph_putsa_fx(), which I actually did weeks ago), and OP and MAIN have their own unique functions in between the shared ones, so…

[C decompilation] [th02/op] Second set of sound driver calls So yeah, after ignoring this issue for a week, we indeed have no choice but to decompile these functions into this horrible mess of C and inline assembly. And you know what? Since the compiled result still matches with ZUN's binary, it's entirely possible that this *was* the original format this code was written in! Seriously, how intoxicated do you have to be to write (or rather, slur) code like this? Keeping these functions entirely in assembly would have surely been better. However, it would have made linking practically impossible, especially for the later games which still need them in the current assembly slice format.
