What this mod adds

This is an unofficial build of PPSSPP with two additional texture extraction tools added to the Developer Tools screen (Settings > Tools > Developer Tools > Texture Replacement).

These tools are designed for PSP games that store textures in GIM and GMO formats such as Dissidia 012 and similar titles from the same era.

Dump All Textures From Folder

Extracts textures from a folder of .gmo and .gim files on your PC (e.g. files extracted from the ISO via another tool).

How it works:

• You select a root folder containing .gmo / .gim files (searched recursively).
• Each file is scanned for embedded GIM image blocks by their magic bytes (MIG.00.1PSP).
• Each GIM block is loaded into PSP RAM and passed to PPSSPP's internal texture dumper.
• Textures that need unswizzling are detected via the c16 field in the GIM block header (c16 == 8 → unswizzle). Stage/environment GMOs containing geometry (Shape string present) are unswizzled; character GMOs are not, even if the flag is set.
• Output PNGs are saved to: Documents\PPSSPP\PSP\TEXTURES\<GameID>\new\<filename>\

Note

• GMOs that contain only animation/skeleton data (no texture blocks) are silently skipped.
• If a GIM block causes a memory fault it is caught and skipped; processing continues with the next file.

Dump All Textures From ISO

Extracts textures directly from the currently running game's ISO filesystem without needing any external files.

How it works:

• Scans all files on disc0:/PSP_GAME/USRDIR recursively, including .bin, .dat, .pac and other container formats.
• Each file is scanned in 4MB chunks (with 64KB overlap) for GIM magic bytes.
• Found GIM blocks are loaded into PSP RAM and passed to the texture dumper.
• Swizzle detection uses the same c16 field as the Folder dumper.
• Output PNGs go to the default PPSSPP texture replacement folder for the current game.

Note

• This tool finds GIMs embedded inside any container format, not just standalone .gim files.
• Swizzle correction via c16 is applied, so textures that were previously exported scrambled should now export correctly.
