[Stock]
fss0={sd path}
stock=1
Can now work for both older and new HOS versions.
- <= 6.2.0 loads nothing and removes kernel patching.
- >= 7.0.0 loads exo, wb and removes kernel patching.
This requires that fss0 {sd path} is valid. Otherwise it will fail on ini cfg parsing.
If <= 6.2.0 and no FSS0
[Stock]
stock=1
will provide a cleaner stock with no kernel patching.
