Monster Hunter Portable 3rd mod loader + file replacer

A delusional lance main's attempt at making a mod loader.

File replacer format

Files for file replacer should be placed in ms0:P3rdML/files/, and should be named as their file id/index.

Mods file format

Mods are now divided into multiple mod files, with mods.bin now containing tables with their paths.

mods.bin Format

Type	Description
U Byte	Path length
Byte[n]	File path, starting with / and ending in 0x00

• Max path length is 22 (not counting the / at the start, nor the null byte at the end).

mods.bin must end in 0xFFFFFFFF.

Mod file format

Mod files must contain mods in the following format:

Type	Description
U Int	Load Address
U Int	*Mod Length
Byte[n]	Mod content

• Most significant bit from Mod Length is used to determine if the mod should be run as it's loaded.

and end in 0xFFFFFFFF00000000.

File structure

• ms0:/P3rdML/mods.bin should contain a list of mod files.
• ms0:/P3rdML/mods/ should contain mod files or folders.
• ms0:/P3rdML/files/ should contain all the files to load as replacements and patches.

Notes

• Replacement files must be named after the file id they are supposed to replace. All letters must be capitalized.
• Patches must follow the mod file format and be named XXXXP, with XXXX being the id of the file to replace.
• Currently a file cannot be both replaced and patched at the same time.

Required files

• Decrypted eboot.bin
