2) I would hardly call it free. Even if you get past all the ridiculous trials to using Dolphin, you need an extremely good computer to actually run it. To get good audio, you need to buy more crap and already own a Wii. And then, even if you finally manage to USE Dolphin, get it running fine and all of that, buy the AC controller adapter, and have everything running...you still get a slightly watered down experience with FPS not always being 100% reliable, several graphic glitches taking place, and a lot of work put into something that is technically illegal. For all the work, effort, and cost, you would be better off buying a Wii, Wii U, Wind Waker, and Wind Waker HD.
In short: Common Man's technology is not ready to emulate GameCube games. Heck, it's still only able to emulate N64 games with semi-reliability.
1) Wrong wrong wrong. Alll wrong. My PC is not even close to "extremely good" and I play TWWJP with full 30 FPS constantly. Here are my PC stats:
Windows 7 Home Premium 64 BIT
AMD Athlon II X2 220 Processor @ 2.80GHz
4GB RAM
Galaxy GeForce GT520 1GBVRAM
You know what that is? $300 - $400 for a Walmart OEM, X amount of money for 2 more gigs of ram, and $50 for the Graphics card update. At max, you'll be spending around $500 but all for good cause: a slew of emulation, and a lot of PC games at the touch of a button. And let me say something real quick to you: this setup is absolutely horrible for PC gaming at default settings (all mediums), but maxes Zelda out. Regarding
Zelda, I experience not a single graphical glitch, not once. In fact, TWW on this crap setup is running better than it does on the GC - it's native platform! I play TWW with my PS2 controller and it's incredibly simple to set up. Furthermore, emulation is not illegal, owning an ISO/ROM is not illegal*, and emulating your legally obtained ROM/ISO is not illegal.
*If you rip it yourself (and own the game in question), having a backup is legal. Downloading games illegally off the Internet is [obvious] completely illegal and not even close to being endorsed.
2) Again the game is very expensive, so finding adeal anywhere is tough.
