Is there a way to have dual booting firmwares on your PSP? I have 5.00m33-6 but am interested in playing Metal Gear Solid: Peace Walker demo (and full game when it comes out), which I heard worked with a GEN CFW but not the latest M33. Advice/experienced input appreciated!

You'd need a modchip to do this, since a modchip is capable of booting firmware off of itself.

Not so much duel booting but make a NAND dump of each and restore when needed.

That was for PSP1000s on 2.71.

Well, I won't be getting a mod chip so would it be better realistically to just load the GEN CFW on my second PSP?

Again, not so much dual booting, but you can swap them out as necessary.

5.50 GEN-B2 will now let you use Hellcat's Recovery Flasher. Make a flash backup of m33-6, then install up to GEN-B2, make a backup of that too.

Alternate at will. Probably safer than a physical NAND backup/restore.

OK, thanks for the input, guys. I'll look into Hellcat's Recovery Flasher (never heard of it) and post back if there's any issues.

Just read the thread i posted earlier about an "eboot patcher" it makes ALL new games work on m33. Simples!
