It doesn't seem to be working, but try it for yourself when you can just to be sure. How did you do that, btw? I searched a bit (probably not hard enough) but I didn't found how to create the modules. In the end what I did is going for the easy route and modifying again the scripts.rxdata I had already modified to make it read the mods folder, even if it isn't the most elegant I'm afraid it's the best I can do, hahaha.
To modify the .dat files what I modified the pbs files and then had RPGMaker compile them.
