So Nintendo adding no options to their emulator is just lazy... thought so.
Nintendo has ALWAYS favored accurate emulation to a fault for their previous consoles. Meaning no smear-o-vision and limited post-processing choices.
new 3DS owner here. Seeing this stuff really makes me wish they would go the extra mile and 3D-ify some of these older games; it seems kind of silly to get psyched up for playing them, after all this time, on a system capable of doing 3D (and the classics games I've downloaded, I am really enjoying). I realize it's pretty much been just a single company doing the 3D effect on the current crop so far, and it looks like they've done all they're gonna by now (if not, then close to it).
I realize a big issue is time and cost, plus the source codes/people who want to actually deal with such things are probably not exactly very available. Can't help but think that "if it was a community-supported project, you'd probably see tons of 'patched-to 3D' games" and that just makes me feel like the people who run this service are a little lazy
Still, it is what it is and it's true "well there could be NO VC service at all" so I guess this is obviously wayyyy better than nothing.
You couldn't automate it at all, or even port it correctly. A lot of these games didn't actually have everything on one layer or even of the same type, so these games would look totally screwed up if you tried to automate 3D somehow. A port would be based off the same code, so the same limitations apply. You'd have to basically remake the game as a 3D Classic anyway.
Auto-3Ding N64 and GameCube games is much more feasible, since they have. well.. 3D data already present.
