Hey!
Sorry for the late reply.
It seems like you need .NET Version 5. You can get it here:

I hope this helps. :)
Viewing post in RPG Maker 2003 - Controller Support comments
One more thing when I run RM Launcher how do I turn on the DPAD to be used for movement? Is that thru editing the DLL like you said above or using the RM2K3 Controller Support to turn on Number Walking for it to work without editing. If thru editing what would I use to do that?
( Edit: Nvm I got it lol up down left right on DPAD in the "" sections for the respective directions in dll.config for the DPAD)
Also there's a bit of input lag when DPAD is enabled for those directions in game, works perfectly through left analog though.
