Thought I'd answer the question regarding the FREE region-free homebrew app. in this thread rather than the old one.
Obviously it won't allow you to play backups (which you shouldn't be doing anyway), but apparently it does work pretty well (I've no NTSC games to try it out, however)- only going by the forum postings at DCEmu
Since it's a TOTALLY FREE software solution that can be upgraded rather than a purchased disc (like the Freeloader) it should be easy for the devs to release updates to non-working games.
Now - onto the subject of Homebrew
in general on the Wii. This is totally legal, and I can't see any problem with posting info about it here (I e-mailed the mods, but no-one replied...). It doesn't invalidate your warranty since you're performing no hardware modification whatsoever to the Wii - however by installing the Homebrew Channel you are copying something to the Wii's memory that isn't certified by Nintendo...
So, at the moment, if you have a bog-standard Wii it is very easy and possible to run a plethora of homebrew apps including emulators for the following systems:
Sega Master System/Game Gear
ScummVM (old-skool LucasArts point-and-click games like Sam and Max, Day of the Tentacle, Monkey Island et al)
Other things of note are things like the Wii-port of the original Quake
- which works with full Wiimote and Nunchuk support for a nice control mechanism. Amazing stuff, really!
To get this lot working, all you need is a copy of Zelda: Twilight Princess
and an SD card (SDHC cards and those bigger than 2Gb are NOT supported yet) - you may need a Gamecube controller for some of the emus, althought some of the unofficial versions now have Wiimote support built-in.
The first thing to do is grab a copy of the Twilight Hack
- a save-game for Zelda: TP that has some hack applied to it, which when loaded in the game allows the Wii to execute other code...
Find it (and a host of other info on homebrew for the Gamecube/Wii) here
Load it onto your SD card in the appropriate dir. Backup your old Zelda save first if you still have one (since the Wii only allows you to have one save-file for each game on the machine at a time).
Next, once that's on the Wii - I've found the simplest way of executing the home-brew code is to use the excellent Homebrew Channel
. This is still in beta, but is an amazing bit of coding - looks totally like an official Wii channel with lovely graphics, interface and music!
Basically grab this elf file, and stick it in the root of your SD card as "boot.elf" - boot Zelda, load the hacked save-game, then just walk backwards - the code should start to execute, and install the channel onto the Wii.
You don't have to use this method if you're not sure about installing something directly onto your Wii - there are plenty of other methods of launching home-brew using the Twilight Hack without having to install ANYTHING (bar the save-game, which is only that - no more). See here
or the Wii forum
over at DCEmu for some loaders that allow you to have multiple emus/homebrew on one card and choose each homebrew one at a time.
The downside to not using the channel method is that you have to more or less reboot the Wii and reload Zelda each time you want to switch emus/homebrew...hence the convenience of the channel - but a nice solution if you don't want to install ANYTHING on your console.
So once you've installed the channel - follow the instructions at the Homebrew Channel URL on how to install apps onto the card including the conventions on creating icons/menu entries for the software...I've found a good pack of apps that you unzip and just copy onto your SD card all ready to go here
Obviously there are NO instructions from me on how to obtain ROMS etc. - you should obviously only be doing any of this if you own the original games concerned.
Other capabilities of this lot obviously include being able to do naughty unsavoury things like installing dumped VC and WiiWare games - but I totally disagree with this since it's obviously illegal, and may only persuade Nintendo to eventually finding a way of closing off this Zelda loophole that currently exists to run legal emulators and other homebrew code...
So, enjoy all this, but be responsible...
