1. As you wrote some hours before, I think in file .ini should be set as default options to avoid many problems with use of multiMAN:
# Backup games to these folders:
# Look for game backups recursively in these folders:
# (leave blank for USB (usb_home) root (/) folder)
# SysCalls to mount MOUNT_POINT
2. What about autodetecting PSGroove ver. (PL3 or Hermes) to set
Anyway good work!
