Remaining functions to decomp

[MegaMech]

100% Match not necessary. Func Equivallency is good too. Don't forget to click "Family" in-case there are cleaner matches as some matches may be very fake-matchy.

func_80050E34	https://decomp.me/scratch/PvJ5D	Handling of the player variable is weird. The instructions are correct but out of place

code_8006E9C0

Function	Decompme	Comments
func_8006FA94	https://decomp.me/scratch/ohbAc	Register allocation differences, especially in the first for-loop. Smaller issues are probably the result of some single-line-multiple-variable assignment shenanigans

func_8000B140	https://decomp.me/scratch/ZtfJ3	lots of diffs
func_80017054	https://decomp.me/scratch/Ck7hV	Large diff, seemingly related to an empty if statement. There's also an unused double, don't know if its part of this function or the one after it
cpu_use_item_strategy	https://decomp.me/scratch/FOlbG	Some diffs, 10k score

add_menu_item	https://decomp.me/scratch/1BHpa	Stack differences
render_menus	https://decomp.me/scratch/MatRp	While marked as non-matching there's a ton work left to be done
func_800A1FB0	https://decomp.me/scratch/s1Hod	Lots of register allocation differences, neither the permuter nor I can find any improvements
render_lap_times	https://decomp.me/scratch/mWCHC	Differences seem to stem from the handling of the textColor function variable. The permuter reports an improvement if you make it volatile, but that seems wrong for several different reasons.

menus.c

Function	Decomp	Comments
main_menu_act	https://decomp.me/scratch/93qj8
player_select_menu_act	https://decomp.me/scratch/POeGU	Big diffs or outdated decompme

math_util.c

Function	Decomp	Comments
func_802B8614	https://decomp.me/scratch/cwX7l	unused, SpazzyLemons has made interesting progress. Something about the use/calculation of lenght is screwy

crash_screen.c

Function	Decomp	Comments
crash_screen_draw_square		Don't even bother trying (func equiv).

audio/external.c

Function	Decomp	Comments
func_800C16E8	https://decomp.me/scratch/99CQl	Register allocation and instruction ordering differences, no idea what the source is. Might(?) be functionally equivalent
func_800C284C	https://decomp.me/scratch/B9kUf	Register allocation differences
func_800C2A2C	https://decomp.me/scratch/TS7EW	Lots and lots of register allocation differences, but might be functionally equivalent
func_800C3724	https://decomp.me/scratch/LpM1t	Lots of work left to be done. Has different US and EU versions
func_800C4398	https://decomp.me/scratch/fmmyb	Stack issues
func_800C4888	https://decomp.me/scratch/cqBii	Probably a variant of select_current_sounds from SM64, lots of work left to be done
func_800C4FE4	https://decomp.me/scratch/Lm9EX	Register allocation differences

audio/load.c

Function	Decomp	Comments
audio_init	https://decomp.me/scratch/u7kKh	Matched (ty LLONSIT) :) !!!NEEDS A PR!!!

audio/synthesis.c

Function	Decomp	Comments
synthesis_process_note	https://decomp.me/scratch/htpLe	Probably func equiv. Mix of SM64 EU & Shindou. Some inaccuracies
func_800B86A0	https://decomp.me/scratch/9bF8H	Probably a variant of process_envelope from SM64. Diff is huge, no idea why. Speculation: the version of the ABI we have/use is horribly horribly wrong but is only noticeably wrong in this specific function

code_80091750:

Concerning D_802BFB80
Vetri found that changing

typedef struct 
{
    u8 pixel_index_array[0x1000];
} struct_D_802BFB80;
extern struct_D_802BFB80 D_802BFB80[][2][8];

to

typedef struct 
{
    u8 pixel_index_array[0x2000];
} struct_D_802BFB80;
extern struct_D_802BFB80 D_802BFB80[][2][4];

can lead to matches in the function(s) where its relevant.
But that seems wrong given that D_802BFB80 kind of has to have 8 as its last dimension based on its usage elsewhere in the codebase.
We could redefine it to being a union I guess? Something like:

typedef struct {
    u8 pixel_index_array[0x2000];
} thing0;
typedef struct {
    u8 pixel_index_array[0x1000];
} thing1;
typedef union {
thing0 blah0[][2][4];
thing1 blah1[][2][8];
} the_union;
extern the_union D_802BFB80;

If it makes stuff match, then great. It'd be super fugly, but if it works it works.
