I wondered what stuff is actually possible with GWs launcher.dat (currently v3.2.1) if you don't own the GW card. Here's the list of features, with my remarks, updated with the information from this thread:
- Boot Gateway Mode - doesn't work
- Boot Classic Mode - doesn't work (may work below FW 7.x, but it's still useless)
- Backup System NAND - confirmed working
- Backup 3DS Game Cartridge - confirmed working (even backing up the rom from SKY3DS!)
- Backup 3DS Savegame - working (not with SKY3DS and CARD2 games, better options available)
- Restore 3DS Savegame - working (see entry above)
- Diagnostic Test - working (shows failures because of missing GW, will delete the current game cart's save)
- Format EmuNAND - working (but very useless, needs GW/Classic Mode to boot)
- Install NVRAM - working (also useless)
- Downgrade Console - working (don't try on N3DS, useful for O3DS users, see this guide)
