Image compression

Is there any support for compressed isos for Wii images? Or a way to simply trim roms like paper mario to erase all the rubbish from the image. Nintendo DS has a rom trimmer.

Thank you

Mm...You mean a way to compress the Isos images?
If is that. Right click on the game and select Compress ISO.

Thank you for the answer. I tried but my computer hanged. I wonder if it is a bad idea for wii images. Maybe i should try for gamecube at least.

Mm.....Well I havent tried whit Wii games, the only one I have is SSBB (7 GB).
I have tested it whit SSBM(1.4 GB) and after the compression it weights (1.2 GB).

I have all my Wii and GC roms compressed by Dolphin. There is a pretty bad memory leak when you do it; probably that's why your computer hanged. But it does work and the disk space you get out of it can be pretty big.

Thanks for all the replies, it can be a difference for games like Super Paper Mario (4.7 Gb > 600 Mb) or New Super Mario Bros Wii (4.7 Gb > 400 Mb). I will try with small GC images first.

Can this potentially make the games slower? What i mean is does the emulator have to read compressed data or does it read it just like a normal ISO. Anyway brilliant fuction that went way over my head hehe.

No JohnBlunt,that's not make games slower.Infact i compress all Wii,GC .If you use SSE3(7.6G->5.1G on 5 min) ,it must 3*times compress faster than SSE2(10-15 min)

This is nice info to hear. I just compressed my 4.34 GB Super mario brother down to 558 MB in 2.19 seconds on my Intel E8400 dual core, 4 gigs of memory. Will start doing that all the time if it doesn't hurt performance with reading. Definitely save more games to DVD this way.

I don't know if it's legal to trim iso from disc but I can get rid of "can't save file,file is corrupt".I try with Samurai Warriors Katana and it work
