Woah, is the Wii version of the emulator this complete and good? Having this on my big HDTV would be incredible.
I haven't tried out the Windows version yet, but once I finally got around to trying out RetroArch, it may have been the single greatest addition to my hacked Wii. I don't believe that it's capable of using the filters, but on an actual CRT, it can do wonders with the Wii's various lo-res screen modes and scanlines. Weird screen resolutions from various arcade units like 384x224 are easy and look authentic. It handles arcade games usually significantly better than Mame, often hitting the full framerate (the GUI and handling of resolutions and stretching is much better too), it handles GB and
especially GBA games better than VBA GX, it's better than SNES 9X GX itself at playing games with expansion chips without stuttering or glitching. The Final Burn cores are wonderful. Not every last game is compatible, but it's also one of the friendlier Wii emulators when it comes to automatically restarting after a crash, rather than just hanging at the crash screen and making you hold down the power button on the Wii itself.
The negatives with it on Wii are that yes, the GUI can be a little clunky (though it is relatively straightforward), it definitely isn't as intuitive as Eke-Eke's GX emulators themselves, and to my knowledge, none of the cores have an auto-savestate feature, so if you want to pick up from where you left off, you're going to have to do it all manually (if I'm not mistaken, though, I think you might be able to assign save/load state to buttons?). It also doesn't seem like there's a frameskip feature, so if a platform or game runs slowly, it's pretty much just going to be slow.
As far as I recall, it covers Capcom CPS1/2, Neo-Geo, NES (numerous choices of core), SNES, Genesis, Sega CD, SMS, Game Gear, GBA/GBC/GB, TG-16/CD, VB, WonderSwan. Various other arcade systems. No PS1/N64. There are probably others that I'm forgetting.
Edit: Speaking of multiple-console frontends and 3D virtual arcades, did anyone here ever get one of those
3D arcade frontends from years ago working? I'm sure that they all look really dated now, but they always looked cool to me when I first saw screenshots of them 10-ish years ago.
