Gamecube DOL green screen

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Burning Snes9x or any other Gamecube emulator on a dvd.
2.Running the dol file with cobra 2.1 bios on a viper (normal) modchip.

What is the expected output? What do you see instead?
Green Screen/ Half, flickering static green screen, 'Loading DOL' message 
whithout anything ever happening

What version of the emulator are you using (official, SVN revision,...)?
Latest found on the web.

Please provide any additional information below (Emulator settings, Console
setting,...)
There's nothing special with it, really, I just wanted to get a Sega/Sony or 
whatever Nintendo, Gamecube emulator, (yes I know it can also be done on any 
other console, such as the wii, ps2, ps3 xbox/360... but I just can't explain 
this to myself, wondering how many dozen dvd's I have stupidely wasted trying 
to get it to work, as I tried almost every method proposed on the internet, yet 
could never get a positive result.

No idea, this is likely an issue between DOL files built with recent libogc and 
Viper OS DOL loader, I personally have a Xeno GC and no problem to boot GC 
homebrew, I'm afraid there is nothing I can do about your problem.

There is nothing that can be fixed in application code anyway, it seems there 
was an option to Dollz (a DOL compressor tool) to fix support for Viper but, 
just like Viper OS, this  tool isn't open-source and there is no way to know 
what needs to be done to "fix" Viper support. Is is also incompatible with 
large DOL files like Genesis Plus GX or Snes9x GX so we can not use it anymore.

On an additional note, you might want to ask about your issue on 
gc-forever.com, they might have better knowledge about Viper OS and its 
specificities.

Ok thanks, but what about the homebrew app. swiss ? Do you need a SD-loader to 
run it or is it just a flash file ? 
I had a Xeno-GC a while ago but due to a poor installation I fear I might have 
messed it up quite a bit (well anyway, the console didn't work anymore 
althought it was an 'easy installation').

In any case, many thanks for the help, I really appreciate.

I don't know much about Swiss and never used it as it's quite recent I think.
The board I linked above is the home of its developer (emukidid) who is 
probably the most suited one to answer your questions about Gamecube 
soft-modding in general.

Ok, thanks for the info and the link; I'll check that out right away.

Another way that could work is to make a bootable DVD which directly boots to 
an application that can load DOLs from a DVD (Swiss, GCOM, GCOS,...) instead of 
using the DOL loading function of Viper OS, which is probably limited regarding 
the type and size of DOL it can load.

Hey thanks for the tube there, but I am merely informed on those kind of 
things; what's a 'mkisofs' for instance and another problem is that whenever I 
try to run DollZ3, a dos console appears for just a few seconds and then pops 
out of the screen, as a user of windows 7, might it be that the OS is just too 
recent for the application ?(do you need a previous one such as XP or windows 
2000 ?)

Those are command line applications, you need to run them under a command 
prompt window or using a .bat file. A .bat file is a .txt file renamed to .bat 
which contains the command line as specified in the link (for example "mkisofs 
-R -J -G gbi.hdr -no-emul-boot -b bootldr.dol -o homebrew_disc.iso disc/")

The link at the bottom seems to point toward a thread with a package with all 
the available tools and .bat files, you would only need to follow the 
instructions.
