[Maintenance] [th04/th05] Declare a little-endian BCD score type Only in C land though; doing the same in ASM land actually makes digit accesses harder to read. Part of P0065, funded by Touhou Patch Center.

[Reverse-engineering] [th04/th05] GENSOU.SCR decoding, encoding, and defaults WTF. Fine, let's have separate, micro-optimized ASM implementations for decoding and encoding inr MAIN.EXE, but still, all those minute difference between OP.EXE and MAINE.EXE… This is as far as anyone should reasonably go before decompilation; things will get really ugly with the loading functions once the file name is involved as well… Completes P0063, funded by -Tom-.
