Hello! This is not a question, more an information (in case it is of anybodys concern...)
I had some troubles using the analog pad as a replacement for a mouse with MiceInJoy.opk in DosBox. The left and right mouse buttons did not work. I then replaced some lines in the "analog.c" file not to use "BTN_MOUSE" but "BTN_LEFT" and "BTN_RIGHT" instead.
I used the following source, (the original was made by "Johnny on Flame")https://boards.dingoonity.org/gcw-games-and-homebrew/mice-in-joy-9024/
So if it is not done yet and if the change is reasonable, Johnny or "AntiCat" may introduce the change in the repository and release a new opk (unfortunately I myself are not very skilled in doing so ;-))
