I hope no one minds if I post a little off topic, but since this thread already has off topic posts, here goes.
I have a program called EditCDG that only runs on windows.
Fatty, would you try it out for me on your windows 3.1 setup in dosbox?
This program was created in the year 2000 and I'm not sure it will run in 16bit windows.
EDIT
This program is used for "cleaning" up the graphics in karaoke *.cdg files, otherwise, one needs to use a Hex editor to do this, and that is really time consuming.
