Pause key not working in PCjr game Demon Attack

MX9000 commented 9 months ago

Describe the bug

The manual says that you can interrupt the game with the PAUSE key on the PCjr keyboard. eXoDOS uses DOSBox Staging version 0.81.0-alpha-1770-g904cb68f9: the game pauses with the Fn+Pause/Break key combination and resumes by pressing the Num Lock key. In DOSBox-X the game freezes often with a hanging note and no longer comes out of pause. I also tried using Ctrl+Num Lock as recommended here: http://brutmanlabs.org/PCjr/pcjr_keyboard_diff.html.

Steps to reproduce the behaviour

Boot Demon Attack cartridge
Try to pause and unpause the game in DOSBox-X and eXoDOS

Expected behavior

The game should go in and out of pause.

It looks like the PCjr never had a Pause key anyway. https://deskthority.net/wiki/images/f/f8/Pcjr_front.jpg so the key shouldn't do anything.

However if non-PCjr modes have a problem with Pause, that's an issue.

According to that picture: Fn+Q = Pause?

Although I don't see that listed here.

PS. What is "Ctrl/PrtSc (Echo Print)"?

MX9000 commented 7 months ago

Yes, @Torinde, also the first version of the PCjr keyboard has a Pause function associated with key combination Fn+Q. Thanks.
