[quote name='nintendokid']I think I remember reading somewhere that Wii will be using hardware/software emulation to run GCN and Virtual titles as opposed to direct hardware emulation or software emu (XBOX360 backwards comp). That means that it'll be spot-on, in terms of controls, music, graphics, pixel/polygon rendering, etc.
Emulations like Final Fantasy Anthology/Chronicles, the disc did all the effort of emulating (ps1 did not have any SNES-like mechanic) so that is why the screen didn't fit fully on TVs and the music, especially the wind effects, instead of sounding "swwisshhh" sounded something more like "vvvvrrrrrrr".
XBOX360 emulations are even worse because they use programs to "trick" the 360 hardware into emulating XBOX titles. That is why you get the more polished look of certain games like Halo 2. It's basically being forced to run on the 360 hardware. In turn, codes and calculations don't always match up.
PS2 did a great job of backwards emulating because it basically had a ps1 core in the console built on with the ps2. It is similar to what Wii will be like, at least to my knowledge.[/quote]
I believe the GC games will be running solely on the Wii's hardware without software interference (remember? "Gamecube 1.5!!1 LOLOLOLOZzzz!11"). The other titles will be software emulated. I daresay the Zelda compilation discs were tests of some of their emulators, and they've likely matured a lot since then. The software emulators, while weaker than hardware, can be tweaked for every title, and patched if things are foudn out to be broken.
I just pray that we avoid the disaster like the offically-released Sega Smash Pack for the Dreamcast. That was some of the worst emulation I've ever seen in a professionally produced product, putout by the company who made all of the original hardware and software no less! Ugh.
