Hi there,
Sorry you didn't find out about this project sooner. ^^; And yes, R18 is a pain in the backside. However, compared to DMM, R18 is like a dream! DMM backend is truly a nightmare to reverse engineer.
PS: I previously used Ubuntu, until I got tired of their instability and frank'n-gnome-like desktop. Moved to Debian LTS and it's solid as a rock.
