I mean, I'd assume bytes. 100 bits is only around 12~13 bytes, which isn't even the full header. And I just tested it anyways and it doesn't match either.
Setting load bios to true in data/database/config/MarioSunshine.config crash on boot, setting "UseDolHash" : false, as well as taking out hash data in rom.json the game boots. I'm gonna try to strip out stuff in the config files to see what's really needed to keep the game running.
What tools are you guys using to get all the different hashes?

It seems like only the dol hash can be disabled, not the others unfortunately.
They used the PAL ROM as a base, hence it running at 25. The 'keyboard inputs' / unusual characters are done so they can overlay something like '^' with a switch button in the overlayed font, and the cut out voice clips are done so they don't have to rerecord lines or anything.
I'm back online for a bit, I'll do some testing myself now.

So here:
Inside the json is this:
Mxic { Hashes } Look like ROM addresses to me. I'll see what's at there in the gcm.
EDIT: The GCM doesn't contain that much data. I'll search for those values just in case, at least.

For those wondering about the FPS, the PAL version of the game can run both 50hz/25FPS or 60hz/30FPS but to get the higher framerate you had to hold B on boot.
If you look in hagi conf iirc it has an option so the emu always sees the B being held thus it boots 60hz/30FPS on the switch.
I also saw a tweet about a sound that seemed like a censure bleep but after checking both PAL and NTSC copies in dolphin the sound is the same however the one on the switch is louder for some reason.
Also there seem to be bindings for keyboard and GC pad but the emu doesn't use them as its set to a different "port" that only has the switch, if someone could enable them and see if they work that would be neat.

Maybe set ‘use dol hash’ to false, or comment out/remove hash related categories altogether.... see if ninty actually made them a prerequisite
edit:
looking forward to a compatibility list soon
@KiiWii already suggested this but it was missed
Maybe nulling it would work - but I'm not sure. Looks like compiled code to me? Disassembly when /s

I'll see what happens, will report back in a bit

Questiom: how much of the data of the 3DAS Sunshine GCM file is the same as an older, GameCube GCM file?
That could lead to clues. Maybe a hex compare between the two (or maybe a few different versions compared to the 3DAS version) will lead to some answers.

I found a github repo named after one of the terms in the hex data you posted, though I'm not sure how much it will help, or if it will help at all.

glad I could help with the sha-1 suggestion. now, it's time to get very stoned. would be interesting to try to figure this out in that condition.
I've pulled out every single piece of text in
data\database\hagi\MarioSunshine.json
I didn't mess with the input sections of
data\database\config\MarioSunshine.config
But everything else I removed and the game seems to boot. Everything except under Boot: LoadBios, which must be set to false. The game boots with every other setting removed, though stuff like image quality and aspect ratio and stuff will be different than the Nintendo intended operation.
Pretty sure the hagi.config in root is just an example file also. Though it could be the default settings? Either way the gcm is still booting with default or no settings except the loadbios setting.
The opening post tho sounds like it's gonna be the right way to go, set up our own NewGame setup and try that, just trying to see what a minimum setup would look like. There's not been any references to the media replacement tho, so just injecting over sunshine might be more complex than just these settings files.

the bios is probably the gamecube splash screen when you load a cube game on the real system.
