Temporal Flux

I just recently found this program, But it is absolutly amazing.
Of course- You need an emulator and rom and all that crap.

But to the point... This program can edit maps, locations, and EVENTS! So in essence, you can create your own story with the chrono trigger battle system and characters and stuff. (you can get sprite editors. and text editors to cover all bases.)
Legally you need the actual game to play the rom, so try not to do anything too stupid, kay?
You can get it here

edit- Just found this out; It has a text editor built into it. Should've figured.
