This topic includes links for complete rips out of DAC. The person supposedly did a lot of work doing so.
But none of the links work anymore. They all say "Http/1.1 Service Unavailable".
It seems like every download link posted before 2013 doesn't work anymore... 
Can anyone who downloaded these rips reupload them? I'm really interested in getting these samples, especially considering that most of these games are impossible to rip without extensive knowledge of compression. These rips also include tools to decompress the samples. Even worse, none of these rips seem to be anywhere else online...
Also, whoever said Cannon Fodder for the GBC uses 4000-5000hz is WRONG. It uses 8000-10000hz, but it's 4-bit, so it can't be extracted properly with Audacity.
