Hm, I remember something like that, yes. Makes sense. Ah well, that means I will have to find a portable version of XTEA code. I wish I could be angry at someone, but the only ones that are "bad" here are ARM designers, and I can't really do anything about them ;) -- Ivan Vučica -- Croatia -- ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
