Oh, I got ROMs. I've had ROMs since the 1990s, and I'll likely have ROMs for the foreseeable future, at least until Internet Archive shuts down. Pre-installed ROMs are great and everything, especially when special formatting is necessary to make them work with the handheld, but I would likely just swap out the SD card with a better one anyway. The default SD cards are supposed to be crap, which is why one of the first things I did when I bought the Data Frog is copy all the data to a Samsung.
Nintendo 64 is not a high priority, nor is the Nintendo DS. PSP would be nice to have, but I do have a buttload of PSPs and Vitae, so it's not totally necessary. In fact, I would probably be happy with the PSP for emulation if it was a bit peppier. It has a HUGE variety of emulators, with new ones coming out as recently as 2019 (!!!). You'd think the Vita would be just as good for emulation, but it... kind of isn't? It's more powerful hardware, but also DIFFERENT hardware, so while it can emulate the PSP emulations of other game systems, emulators designed specifically for the Vita tend to suck ass. Maybe while you guys are porting Android games like Shadowgun to this thing, maybe you could port a few Android emulators, because they'd likely be way better than what the Vita currently has. You get toaster-riffic performance out of pFBA... it's just shameful. And MAME/FBA is pretty lousy across the board on the PSP... it's not powerful enough to handle an emulator that supports thousands of disparate machines, and it really shows in the performance.
