I tried to run Keymaster in GZDoom 3.7.2, but I got 2 errors.
The Lines are 75 and 162 in handler.txt.
The result is an error "Invalid Statement".
That's why I can't run Keymaster at all.
Is there any way to fix that?
This is due to a bug in the GZDoom 3.7 series; GZDoom 4.0 was just released and does not exhibit this issue, give that a shot: https://forum.zdoom.org/viewtopic.php?f=1&t=64188
