 ## Build Instructions
 - Dump a copy of the debug version of the game and extract the main.dol
 - Place main.dol in the orig folder
-- Place the Codewarrior Compiler in tools/2.5, 2.0, 2.6 and 2.7 might work too
+- Place the compilers of GC MW 2.5 in tools/2.5
+- Place the compilers of GC MW 1.2.5 in tools/1.2.5
 - Install DevkitPPC, Ninja and Python
     - DevkitPPC r38 and r41 are known to work, other versions probably do too 
     - NOTE: if on Windows edit the environment variables to the location where you stored Devkitpro
