* Add parens around params usage in VEC_SET macro * Remove unnecessary space character in a xml * Use defines instead of magic values in head/tail magic comments * Use `OS_USEC_TO_CYCLES` to make a time look better in `Graph_TaskSet00` * `0x25800` -> `sizeof(u16[SCREEN_HEIGHT][SCREEN_WIDTH])` * `0x803DA800` -> `0x80400000 - frame buffer size` * Use `OS_VI_` defines instead of hex * Add empty line after some variable declarations * Remove unused `extern CutsceneData` in `z_bg_dy_yoseizo.c` * `Matrix_MtxFToYXZRotS` does not use `MTXMODE_` * Use `MTXMODE_` more * Remove `ASCII_TO_U32`, use `'IS64'` * Add explicit `!= NULL` in some ternaries * Use `INV_CONTENT`, `AMMO` macros more * Use `PLAYER_AP_` enum more to compare to `Player#heldItemActionParam` * Get rid of lowercase hex (outside libultra) * `gWindMill*` -> `gWindmill*` * Format and small fix enums in `z_boss_mo.h` * Use `CHECK_BTN_ANY` more * Fix xz/xy mistake in comment in tektite * Rephrase comments mentioning "the devs" in a more neutral way * Clean-up some objectively useless parens * Fix some negative values written as u16 instead of s16 in ichains * `SKJ_ACTON_` -> `SKJ_ACTION_` * Run formatter * Fix unk_ offset of `TransformUpdateIndex#unk_10` -> `unk_0E` * Remove comments using in-game text * Remove `U` suffix from integer literals * Revert "Remove `ASCII_TO_U32`, use `'IS64'`" This reverts commitc801337dde. * Use `PLAYER_STR_*` to compare to `CUR_UPG_VALUE(UPG_STRENGTH)` * Add empty line after decl x2 * Revert "Use `PLAYER_STR_*` to compare to `CUR_UPG_VALUE(UPG_STRENGTH)`" This reverts commitd80bdb32da. * Make `CUR_UPG_VALUE(UPG_STRENGTH)` compare to integers (eventually needs its own enum) * Only use `PLAYER_SHIELD_` enum with `Player#currentShield` * Only use `PLAYER_TUNIC_` enum with `Player#currentTunic`
