VitaPad VS Player

Pretty cool, but VitaPad already exists. You might want to choose a new name to avoid confusion

Go to the project page, see if you can find what you're looking for, maybe create an issue or try to contact one of the contributors.

I believe Vitapad supports xinput.

You can play them with EasyRPG Player, the fps varies game to game

I had a similar issue before. I think it had something to do with the fact that people used to make games on pirated versions of 2K3, so there are multiple versions of the RTP floating around and stuff. In the end, I just wound up downloading EasyRPG Player. Just dropped Player.exe into the game's directory, and used that to execute the game (instead of RPG_RT.exe), and it worked like a champ.

quick search says it works with that: https://github.com/EasyRPG/Player

Otherwise, you can also try EasyRPG. I think that would negate the need for you to install the RTP in the first place.

Grab yourself some copies of EasyRPG Player!

Sounds like you're trying to play an EasyRPG created game. Those files need be run through the EasyRPG player.

Oh, never mind that, I can't wrap myself around MacOS. You've gone through so much effort. Use EasyRPG player for the 2000 and 2003 fangames.
