Rekai Nyangadzayi Musuka e380af7056 chore: use a more efficient decimal->bcd algorithm 
This will not improve perf in any way because this code only gets run
one time a second orz

Rekai Nyangadzayi Musuka c0e583d20d fix: resolve off-by-one error in `str` addr when r15 is involved 
I seem to have made up this rule (I was thinking about when r15 was
a source register). `rn` is the destination register.... whoops

Rekai Nyangadzayi Musuka 0de44835e5 fix: properly implement black/white blending for sprites 
There's unique rules to handle for BLDY w/r/t sprites, I didn't know
about them (shown in bld_demo.gba). I'm sure I haven't ironed out every
rule but bld_demo.gba now *actually* passes

Rekai Nyangadzayi Musuka 5aac04faf5 tmp: disable buggy window emulation 
I'd like to merge my affine sprite impl into main, which will require
merging a lot of the rewrites I did in this branch. My plan is to
merge the buggy ppu window impl to main, but keep it disabled.

This is technically a regression but the current impl barely worked
anyways so....
