That sounds *very* interesting.

I don't know when What information would that be? The equivalence of texture / surface / memory region numbers? I don't know whether abusing NOPs for that is actually the right idea, though. > i will have time to tackle this, i always have great hope of doing it soon > but each time my day end i am just totaly exhausted. ...

Not that I intend to do anything TTM/GEM related ATM, but I'm curious. > Oh and have fun with r6xx =) Thnx :) Matthias -- Matthias Hopf <[EMAIL PROTECTED]> __ __ __ Maxfeldstr. 5 / 90409 Nuernberg (_ | | (_ |__ [EMAIL PROTECTED] Phone +49-911-74053-715 __) |_| __) |__ R & D www.mshopf.de ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
