To be honest, I'm not really interested in making "new" adventures with hacking. I prefer to improve upon the official releases of games, so as to make "definitive" versions of them while still keeping them feeling as legitimate as can be. Obviously I'm limited to what I can do on that end since I'm unable to do ASM hacking, but I still do whatever I can with them. FireRed/LeafGreen is only the third game I've worked on (second with a public release), so I can't pretend that I do it with a lot of games. I do wish I was able to do more with them!
PokéCommunity only sees those "new" adventures as fitting for the main sections, so my hack is restricted to the Sideshow Showcase section by default.
