Hi, my first message in the forum, i think i can help a bit with .sfo stuff
Vikin KLM, notice the variable ATTRIBUTE can trigger some "special boot parameters" (32 "flags" to be exact)
I never looked at PSN content, but i guess there must be some special ones for this
Either way... "SFO editor v0.8 beta" (the windows version made by hellcat) has a bug that erases the last bytes of the ATTRIBUTE
Btw... some varables can be addedd or removed, i found some ones, but never looked at PSN content
Maybe is needed to remove something ?
