Dragon Quest VII via a 3ds emulator.
Gonna play DQ VIII next.
I've also ripped Ocarina of Time, Majora's Mask, and a few other titles including Metroid Return of Samus. I have several raw roms that still need to be decrypted as well. No hurry on that, and it doesn't take but a few minutes once I figured out the tools.
The 3DS emulator I'm using is Citra and 3DS emulation is still in the earliest stages. Basically, a lot of games don't work and what does isn't perfect. I don't recommend checking this as a method for playing 3DS games unless you're into emulators like me. It's not well optimized yet and you're better off sticking with a real 3DS for probably a while yet, maybe a year or two.
Learned how to rip the ROMs and decrypt them though, which was an interesting afternoon in itself. This is on top of having to decrypt the ROMS themselves.
It's also worth pointing out that it isn't as simple as just getting some ROMs and loading them into the emulator. You actually need some system files from a legit 3DS to get some games working that the emulators can't legally include.
I got myself a New 3DS, so I had one that I could use without worrying about bricking my only one, so I decided to look into emulators. I didn't get it for that reason, a couple of the buttons are getting kind of sketchy on my old one.
Also, I hate the way Nintendo sets up their controls in a lot of games, and the fact that they don't usually let you edit them. I really don't get why consoles do this, it's not that hard to add an editor for controls so you can set up the buttons and triggers how you want. Emulators let me do this. Nintendo is just the biggest offender of the bunch for creating awkward controls and not letting players do anything about it.
Despite some minor issues, it mostly runs good. I can use a gamepad for the basic controls, and the mouse for the touch screen stuff. Some games I wouldn't bother playing this way at all, but there's plenty that works really well with this control scheme.
I can also adjust how the screens are displayed, and thanks to Steam I can set up my controller to handle hotkeys for the emulator itself, as well as the basic game controls.
It looks amazing though, relatively speaking. The games look like crap without upscaling on a large screen, but the emulator does a nice job cleaning things up considering what an early state it's in.
It's also surprisingly stable for such an early state. Haven't had any crashes yet. Some stuff that wouldn't boot up, but once something runs it stays running so far. Though, DQ VII is the only thing I've spent a considerable amount of time playing and that's just an initial impression.
The last screen is just one of the configurations for dual screens. I can also do side by side, and have either of them as a very small screen in the corner. I can also swap between which is the larger screen, or as the other shots show, just make one of them full screen. Which is best depends on the game.
For something like DQ I'll probably play most, if not all of, the game as a single screen. I'll probably play several JRPGs this way in the near future.
You can also see in the text how grainy it is without upscaling. For some reason the text remains grainy. A lot of cutscenes and such are also like this, but the gameplay looks as good as the screens show for everything I've tried so far.
Also, they haven't figured out Pokemon yet. It's apparently being kind of a bitch to emulate. As well as the 3D Mario title. Some stuff runs really well, other stuff runs, but at a terrible framerate. The emulators themselves are not very well optimized yet, but when it's good, it's really good. There's a lot of potential here.
Also, being able to use the mouse for the touch screen is better in some cases, and not so good in others. It depends.
A PS4 controller is really nice for this. The touchpad makes for a nice replacement for the touch screen, and it has two analog sticks for N3DS games that support it, which the emulator also runs. If you've got it as an option and decide to try emulating 3DS games, I highly recommend using the DS4 controller for it.
