# Yu-Gi-Oh! GX Tag Force: matching PSP decompilation with REA analysis

> Yu-Gi-Oh! GX Tag Force reconstructs the North American PSP game's runtime and game modules as C. The build compiles the C with mwccpsp, compares the result with the original and retains unmatched parts as assembly. Architecture notes cite REA evidence from Ghidra analysis of the BOOT module. A playable PC port remains planned.
