For those who have programmed in BASIC.
There is a utility that enables you to run scripts that enter input. This is especially useful in automated game playing, like I was able to get about 500 speed sources and 1000 luck sources in FF7 (with the appropriate materia like Sneak Attack). Basically, I can have my party encounter 100's of monsters and level up with me checking the progress every 20 minutes.
Google autoit. I'm sure some of you have heard of it.
