Should be fun to hack that in to the current design. Huh, I wonder why I didn’t think to use the disk for storage — only every decent Windows trainer does!

Figured it might be AppArmor being a dick but turning it off made no change. Turned on debug output for mono which spat out some merry 1500 lines or so (http://apache.dataloss.nl/~spidey/debug.log) and the relevant error seems to be: DllImport error loading library './libtursiopsglue.so: failed to map segment from shared object: Operation not permitted'. Googled a bit for it and it seems to be common with SELinux but that I don't have. I tried turning off AppArmor (as I figured it has some things in common with SELinux) but that did not resolve anything either. Any ideas?

I'll work on that for the next release. @Daniel: Are you running this from the directory where Tursiops.exe exists? Is there a libtursiopsglue.so in the same folder?

One thing I noticed is that overflows are not handled by this program - put in a big number to an int8 value and the program crashes. But otherwise, great program! I came to this from a search for kcheat binary, as I didn't want to run KDE 1!
