maybe implement the ready to send bit in dosbox itself (at the speed of a rev 000). This would elimate the need the need for configuration parameters). I think Srecko once coded something like this, but he had problems with one game recognising the mt32 then. This might currently not be an issue …

Hi, Thanks for debugging this. When app sends 0xFC it usually means that it tells mpu401 to stop requesting midi data. After that (after all internal tracks of mpu401 that were active were shut off this way), mpu401 will issue back 0xFC as a signal to the app that it's finished. What happens …

The input patch doesn't change how midi output works (aside that because of some refactoring in midi.cpp it could require a manual merging of patch chunks for that file). I haven't been looking at MT32 patches though. So nothing yet.

Uh, I played with Prism (demo version only), but obviously it's still buggy 😒 It goes again on the TODO list, so it will be examined when I'll have enough free time.

I only tried Copper (long time ago) on a Matrox Millenium I, but guess it's not the card which this demo was developed on. There was some flickering, but effects were mostly there. But it seems you figured it out... 😀

It't very simple (if you still need it). If first byte of a MIDI command is 0x90, which is a note on, edit the third byte and put whatever volume you l (it must be in decimal range 0-127). ->code is in midi.cpp

I think that Chuck Yeager also works directly from Windows XP (NTVDM) with PC speaker sound. Is the speech also garbled when you run it that way? (btw. with dosbox, it might be a timing resolution problem)

On my Fedora8 setup timidity works out of box. Probably, look at how to load linux sequencer kernel modules. Or if they are loaded, check if your setup creates right device files for alsa sequencer (maybe you don't have udev set up properly?). Alsa sources come with makedev script (for static …

what is your output of "aconnect -o" ? If there is nothing (except midi through), then your sound card doesn't support MIDI and you need to use timidity which is a Software MIDI synthesizer for Linux. e.g. you start it with: timidity -iAv -Os (Just make sure that you install both timidity and patch …

Start timidity / timidity++ (with proper command-line parameters) if your sound card doesn't support MIDI. If it doesn't autodetect, look at available output ports with "aconnect -o" and write right value (e.g 23:0 etc., of your sequencer output device) to "config" in [midi] section of dosbox.conf. …

I doubt as well that it will work in any emulation (that is not cheating, i.e. heavily patching the kernel to workaround OS limits). Purpose of realtime systems is to get guaranteed latency constraint and guaranteed per-process (high) timing resolution for critical apps. As dosbox usually runs on …

I've seen a game script which utilizes prompt to ask a question. Except a visual change, it remains fully functional in dosbox. Something like Copy code to clipboard 1 echo Do you want to start a game now? (type Y or N) 2 prompt ? Of course Y.bat and N.bat are in the same directory 🙄

Regarding Pinball Fantasies, was the "high-res" mode properly displayed anywhere? (except that dosbox was hacked to display that mode with non-stretched ball). It might have been planned for some special ("insert coin" 🤑) video game machine, though.
