Virtual Script Machine Instructions (VSMX) | Virtual Script Machine Instructions (VSMX) file | ||
* | Used on: | ||
*[[Rich_Appearance_Format_(RAF)|RAF file]] (and so, on [[Coldboot.raf]]) with a filename extension .jsx | |||
*some PSP rco | |||

[[Rcomage]] can decrypt/encrypt .jsx (VSMX) <=> .JS (need to change the VSMX version at offset 0x04 to 01 (PSP?) instead of 02 (PS3?) | |||

but it's very buggy and usually doesn't work right | |||
