Does anyone have the Zardoz C compiler? It sounds like it was used for some SNES projects. Here's an archived page about the compiler: http://web.archive.org/web/19970720124726/www.oro.net/~jimg/cdev.html
Just ask to the webmaster. I didn't find anything on google so try emule or something like that or ask to those who use ftp here
Since he's linking to archive.org, I'm guessing the domain is long dead (and since the webmaster's email address is the same, emails will be bouncing).
From what I can gather this was bought by Western Design. I'm not sure if it is part of their compiler package or not. If it is, they've raised the price 3x. This would be a nice tool for hobby SNES (and Apple IIGS) programming. But, I don't know a hobby programmer that could afford $3000. I wonder if anyone that collects SNES dev stuff has seen it?
