One thing I've been hoping for on the PSP is a good NGPC emu. So far, the current one is still lacking A LOT. I saw one listed here for the DS. I don't have a flash kit for the DS yet, but I have an old EZFlashII for GBA.
I didn't see any documentation on how to actually use the emu for DS, but I saw the gba and ds files in the rar which I assume go on the different flash cards in order to work, but that's not what I'm after right now.
I'm more curious as to how good the emu is and if it's possible to run it on only a GBA flash card? If so, exactly how to I go about doing that? I've used PocketNES and SNESadvance, so I know how those work, but this one doesn't seem to go that way.
I've been debating getting one of the flash things for my DS, but they're still a little pricy at the moment and I don't have THAT much use for one. If there is a good, fast NGPC emu with working sound for the DS, though, I might be swayed into getting one soon.
