[Maintenance] Correctly declare all input functions The pascal calling convention for TH03's input mode functions actually sort of matters, since we have this nice function pointer type that expects pascal.

[Reverse-engineering] [th03/th04/th05] Input change delay function With TH05 definitely being the Galaxy Brain version of this function. You'll see once I get to push the C decompilation for that one… Anyway, that covers all shared input functions of TH02-TH05! Funded by zorg.
