Snap64 Recomp mods

Mods for Snap64 Recomp, the native PC port of Pokémon Snap. Each is one .nrm file, also packed as a Thunderstore zip. They need the port at 1.0.9 or later.

The mods

Unlimited Film

The roll never runs out. Every course still starts with 60 shots, but the counter never falls and the ride never ends for want of film: when the roll is full, each new photo pushes the oldest one out, so the 60 you bring to Professor Oak are the newest 60. A setting in the mod's options lets the counter in the corner show 60 throughout (the default) or count the shots you have taken.

Checked on the released 1.0.9 with a scripted Beach ride that took 108 photos: the roll dropped its oldest 48 times, the ride ended as usual and Oak's evaluation scored the photos. Checked again on 1.1.0 with the port's scoring replay: 45 photos scored with the mod on.

Unlock Everything

Every course open from the start, with the Apple, the Pester Ball, the Poké Flute and the Dash Engine in hand and the Beach tutorial marked done. It sets these in your save the way the game itself does when you earn them, so they stay when the game next saves. Your Pokémon Report and your album are not touched. Copy saves/ somewhere safe first if you may want to go back.

Checked on 1.1.0 from a save with only the Beach open and no items: with the mod on, the course map listed all seven courses, and the Beach showed the three item buttons, where the same moment without the mod shows none. That the change stays in the save is read from the game's code, not watched: the mod's setters write the save the game keeps in memory (the decompilation's src/more_funcs/5BF20.c), and the game's save writes that whole record to the cartridge's flash.

Installing

Download a mod from the Releases page: the .nrm, or the Thunderstore zip, which carries the .nrm with an icon and a README.

• Snap64 Recomp 1.1.0 or later: drop the .nrm or the zip on the game window, or put either in the mods/ folder next to Snap64Recomp.exe (or the Linux binary; on a Mac, the mods/ folder in ~/Library/Application Support/Snap64 Recomp/). The mod loads the next time the game starts.
• Snap64 Recomp 1.0.9: put the .nrm in the mods/ folder (take it out of the zip first).

A new mod is on the first time it is found. Options > Mods in the game turns it on or off, and Z there opens a mod's own settings.

Building

The same tools as the mod template: clang and ld.lld with the MIPS target, make, and RecompModTool from N64Recomp. Check out the decompilation as pokemonsnap and the symbol files as Snap64RecompSyms beside this README (no build of the decompilation is needed), then:

make MOD=unlimited_film
RecompModTool mods/unlimited_film/mod.toml build/unlimited_film

build/unlimited_film/snap64_unlimited_film.nrm is the mod. The same with unlock_everything. Then

python tools/pack_thunderstore.py unlimited_film unlock_everything

writes each mod's Thunderstore zip to dist/: a manifest.json made from mod.toml, and the README, changelog and icon from mods/<mod>/thunderstore/, beside the .nrm. tools/make_icons.py drew the icons from the port's own logo. The CI workflow does all of this from a clean clone on every push.

One thing the template does not say yet: this Makefile passes -fno-builtin-memcpy -fno-builtin-memmove -fno-builtin-bcopy, because clang otherwise turns a copy into a call to memmove, which the game does not have. And at 1.0.9 a mod's hook failed on three kinds of function: one that calls the game's memcpy, one the port's own patches replace, and one that waits a frame (the game stopped when its process ended). Snap64 Recomp 1.1.0 fixes all three. Unlimited Film was written around the first, with a patch of a small function that runs at the same moment, so it runs on 1.0.9 too.
