This is an example of the decodification and decompilation made with the VSMX script contained inside [[coldboot.raf]]. The decompilation has been made by hand because the vsmx decompiler by ZiNgA BuRgA doesnt supports vectors and crashes, the purpose is to serve as an explain of how the opcodes works, the features that was added to VSMX v2 format for PS3, and as an overall explain of how to decompile other VSMX files | This is an example of the decodification and decompilation made with the VSMX script contained inside [[coldboot.raf]].
