An iteration is loading the roms, setting up the emulator, running the game for a short period, and then shutting down which also updates files. It's really testing our code to make sure we write files properly and keep track of everything properly on a long-term basis. The Alpha testers and I have let the game run for days without shutting it off and had no problems. I wanted to make sure no problems would creep up after a few thousand plays.
Good solid thinking there - it's a pity MS don't try the same!!
Probably poor form to quote myself - but just recovered from Vista crashing out. I can still read the disk all my data is on, but it stopped booting up properly, then from logging in properly. Ended up reinstalling on a new disk.
Your software sounds so much better!
