I also want to tell you that your program is awesome and really usefull. It helped a lot in my port of Neko Project for Xbox, as your program makes possible very interesting features, like searching by 2 or more parameters (for example, games that are puzzle AND not-adult... and sort them by year or whatever).
It is a very usefull software, and the fact that you spent your time creating it and released it for free, is very very nice. Thank you very much, peter_j!! I hope you don't become discouraged, I'm sure that a lot of people here think the same than me
