Just tried it out real quick. It's quite awesome, and just about exactly what I was looking for in a tool like this. Few comments though...
- Does this save your previous settings? Doesn't seem like it does when I quit and came back (unless I'm missing something). What I'd really like is to use it like an ini manager for arcadevga. For example, I set up Darius to a smaller resolution because 1024x768 is out of range on my monitor. I then had to turn on hwstretch and then did effect sharp so it wasn't as fuzzy. Then I generated all the ini's. I quit the program and looked at Darius again and there was no info in the popup window. It'd be real cool if it just read the current ini file so I could manage it later if need be and remember what the settings are.
- Related to that is that it'd be cool to have the ability to just generate an ini file for one game in particular. It seems to me you can change one game's parameters, but in order to save it to the ini file you need to generate all the ini's for all the games you have. Since loading up the program doesn't load in any existing ini info, this could be dangerous yes? I know there are times when I play a game I haven't played and realize I should turn off triplebuffer or soemthing because its running to slow. It'd be nice if I could just load this up, change it for the one game, save that one ini, exit and go back to playing.
- I'd also a way to see ALL games for all resolutions in the middle pane. If there's a way i couldn't figure it out. This sorta goes w/ the above. I know Killer Instict is running slow, I want to turn off triplebuffer and vsync, but I have no idea what res KI runs at, so it takes me a while to find it. Having a list of all would be nice.
- Lastly, I'd like the middle pane not to center the text of each column. Being a graphic designer, centered text = no-no. I'm sure most people don't care, but if there was a config file I could change that (or a right click view option or something) I'd be much happier.

Other than that the program is quite excellent. I'm sure as I play around with it more, I'll have more comments. Really cool though. Great job!
