QUOTE said:
Was just wondering if anyone had thought about this.

1. Wii games are encrypted on the disk. The encryption being such that the disk image will not compress - with rare exceptions e.g. Puzzle Quest

2. It is now possible to open up the encrypted discs to see the actual size of the used data.

What would happen if, for example, the ISO image was doctored to blank fill the non-used area of the image with compressable data. It would then be possible to compress it, the uncompressed one still being the correct 'full iso' in size. The game should also still run as no data will be missing and no signing of code required..

Just a thought (and if I didn't have a stinking head cold I'd give it a go)

^Dack posted this for one of his topics.^

Looks as though he went through with the idea. The Wii Scene is going through a great evolution. Great job Dack, Team Twili, and all the others who have been helping out around the Wii community!

Just found a small bug, I don't know if it's been reported yet.

Compressing

Rockstar Games presents Table Tennis v0.1.iso

Returns a filename of

Rockstar Games presents Table Tennis v0(compress).1(compress).i

Just a headsup

Question. For the games that result as less that 700mb, would there be a way to make it so that you could burn them onto a CD rather than a full dvd? I realise that once decompressed the images are still 4gb, but surely if the data isn't used then it's not a problem? No?

I read that Wii dvdrom can only read DVD.

you cant REMOVE things from the disc at the time being
it will be detected when files change location on the disc
you should read more about how this program works

That will be my slack coding of just looking for '.' in the string and replacing it with "(compress)."

The Moh2 display bug is also outstanding.

That's not what i said is it... you're removing blank data. I'm not talking about removing useful stuff...

also note the "i" at the end instead of "iso" it looks like I hit the max string length too.

The blank data isn't all at the end of the disk, if you truncate the iso to 700mb and burn it to a CD you will be potentially missing some valid data so no, stick to dvd's

that's exactly why it cant be done, removing blank data means shifting position of useful data of the game
that WILL be detected by Wii and crash
unless we can sign the disc again (which we cant at the moment)

Ok, thanks. Well... fingers crossed for this and multi game discs in the future!
