[KahazaTester]

Add support to directly use the NUP format.

and the new nx format

There's a pull request for this now: #167 reads the game straight from a .nup dump wherever the setup took the exefs/ and romfs/ folders (the dump still has to be decrypted 1.0.0). It's under review; this stays open until it's merged.

@Walnutoast830, which "nx format" do you mean? A link to the tool that makes it would help.

Thanks, that one is clear: NXFormat (MIT) ships a reader with a C API, so the game can be read from a .nx archive the same way #167 reads a .nup. #167 adds the place where a packed dump is opened; once it is merged, .nx goes in next to it. I will post here when a build reads it.

Both are in main now and come in v0.1.9 (today): #167 (by @Robert-Hoffman04) reads a .nup dump, and on top of it a .nx (NXFormat) archive is read with NXFormat's own reader. On the start screen, Game files > Choose .nup or .nx file; the setup takes the package where it took the exefs/ and romfs/ folders, and with Use it where it is the game reads its files straight from the package (no 23 GB copy).

The dump inside still has to be decrypted Mario Kart World 1.0.0 or 1.8.0. Tested here with the 1.0.0 dump packed both ways (nup pack and nxconvert pack-nup): every file read back equal to the loose dump, and the game boots from each.

v0.1.9 is out: Game files > Choose .nup or .nx file takes a .nup or .nx dump, and with "Use it where it is" the game reads its files straight from it (checked from the release package with both). Release: https://github.com/adriadam10/mkw-recomp/releases/tag/v0.1.9
