Hacking Which Slot2?

[-EX-]

So I should stick with the EZ Expansion pack?
Is it easy to use with the R4 DS?
And I must put the 2 or maybe 3 GBA roms on my R4 DS?

Yes, it's easy to use. You can put as many GBA roms as you want on your R4 DS, but of course you can have only one at time on the expansion pack. The save will be automatically backed up when you flash another rom. Or you can backup save at anytime by just pressing B in the program.

The rumble is still being worked on. There's imperfect patch for Metroid Prime Pinball, but Cory's looking in soft reset code, so the rumble could be enabled without patching the actual roms.

Opera browser works just fine, there's a patch for it.
