I read up a little on the forum. Supposedly you can use a program called Main2Raw to convert the FS to a raw format and THEN use SEFSTool or something to convert Raw to Windows map format. There could be an easier way to do it by now. But as Payne4Life said, you can probably just get a pre-extracted FS online.

Can someone answer: Is the MENU.ML file specific to each firmware version? If I use an extracted R6BC002 firmware to get MENU.ML will it work with my R8BA024 firmware?

Thx
