9ee2b59208 hMultiplicand is four bytes internally, but the high byte is always 0 since allowing four-byte multiplicands could overflow hProduct. 2018-09-09 15:10:38 -04:00

296402bd31 _Divide results go in hQuotient and hRemainder, not in hDividend and hDivisor
Note that the result quotient is four bytes, but hQuotient is a three-byte buffer. This is because no Divide caller ever needed a four-byte quotient, so the buffer didn't include the high byte.

eb1e3636bb Use labels instead of constants for HRAM
Use explicit ldh instruction to access HRAM locations, don't rely on optimizing ld

d3cc861d33 Fix snake_case filenames
Renamed a bunch of files, most of them one-off functions, to better fit
the general snake_case naming scheme. Also renamed some awfully long filenames.

81fff9bb80 Fix file permissions
I have no idea why this was a thing (do people store this repo on FAT32
flash drives or something?), but quite a bit of files had a permission
of 755. This isn't really a problem, but it's inconsistent and weird.

be76ee56a8 Organize the engine/ directory, director's cut
Cleaned up `engine/routines`, in favor of moving files into more
appropriate directories. predef-related routines are now in top-level
`engine`.
`rtc/delete_save_change_clock.asm` has been split into both
`menus/delete_save.asm` and `rtc/reset_password.asm`.

Made a new subdirectory:
* engine/math: Contains all generic math-related routines.
