Display MoreDisplay MoreVery important in RAD-Doom: don't press f7! That triggers a reset.
By the way, the display size can be reduced in the game with - (minus). On the other hand, + does not work for enlarging. But this can be changed again via the in-game menu, which is opened with ←. Here you can even set that the entire screen (without border) is used to display the gameplay. *
It is controlled in the menu via @ (corresponds to cursor up) and ; or Cursor Down (corresponds to both cursor down) or I[ /tt][tt]JKL as "cursor control pad" to navigate to the respective menu item, and J and [tt ]L[/tt] (left/right) or RETURN (corresponds to L, i.e. "right" or "increase") to switch between the respective options. With ← you can return to the game. However, the IJKL keys only work in the menu if keyboard control is set (with f3 switches between mouse and keyboard, which in turn can also be done in the menu). BTW, a 1351 mouse (or compatible) is only supported on port 2 (if you haven't had time to read the README).
* With "Fullscreen" I sometimes had the problem (so not directly reproducible) that the mouse left/right or J / L got stuck in a certain area. When the "limit" was reached, the graphics jumped back, so that only a certain angle range was displayed in this way as long as I didn't move forwards or backwards.
Sorry if I missed the obvious, but where can I download RAD-Doom from?
Look here:
Thank you Wins4, I didn't think to check the Github *facepalm*
