I found this awesome and very useful utility. It’s a Windowskin Generator, programmed by Woratana and with graphics by Aindra, for RMVX and it works! Update: Windowskins generated by this program will also work for RMVXA.
The idea behind this is to make Windowskin creation easy by selecting various parts and applying them to the skin. It even has a preview area where you can see what the resultant image will look like! Once you’re done, the finished product can be saved and imported into RMVX for use in your games.
Download it directly here, then extract it to the RMVX Projects folder (using WinRar or Winzip) and open it up in the RMVX program.
It can be run directly from RMVX or as a standalone program. If used as standalone, the RGSS2002e.dll may be needed. Information on creating and running standalone games (including downloading the appropriate files) can be found on the
RPG RPG Revolution forum (it appears the website is offline.
