ST2 halting

[dbalsom]

MartyPC isn't crashing here, by the looks of it - it is telling you that the emulated CPU has entered an unrecoverable halt (Executed a HLT instruction with interrupts disabled). This is a convenience feature so you don't waste your time waiting for something to happen when nothing ever will.

I tried it on my 5150, and it seems to lock up as well, but I do see "Loading setup..." first, however stopping at a HLT also stops the CGA from drawing so we often miss seeing a string that might have printed out first. I need to fix that...I think I'll just leave the popup that tells you the system halted, but continue to run the system bus.

I suspect this title likely requires a 286. ST1 docs strongly suggested a 10Mhz AT, and ST3 docs say it requires a 386, although ST2 readme doesn't really say what it requires.

If you want to check something should run on MartyPC, use PCE, PCem or 86box configured to be an 8088 CPU. DosBox emulates a sort of generic, 32-bit x86 chip and so will run things that an original IBM PC never could. If you're willing to test that out it would be a great help, otherwise it will have to wait until I can get to it. I'm afraid even if it can be made to run it will run very poorly on an 8088.

I mean, if a program locks up on real hardware, but not in emulators, it's a bug in the emulators. MartyPC is probably correct here.

ST 2.2 now runs

It even quits without hanging!

ST 2.3 still prints an error message and halts, but it does the same on my real IBM 5150, so I am inclined to say that is accurate

Okay so I tried this on 86Box using the "IBM XT (1986)" preset (8088 at both 4.77 and 7.16), used the same FreeDOS then MS-DOS 3 setup, it seems to be running...

the video shows me running the program, running one of my songs, then expectedly crashing it which I fully expected since the lowest speed for playback for PC speaker (which is all I can test cause no Sound Blaster or Covox DAC support, those go down to 5 Mhz playback) is 8 Mhz which is still way too high.

Thanks for trying it on 86box. Just curious - what video adapter did you have configured?

Tried Scream Tracker 2.2 and 2.3 in PCE (5150, 82OCT27 ROM, 8088, CGA, 640K RAM, PC-DOS 3.30).
Both version start to the main screen. Then ST 2.2 hangs when quiting. And ST 2.3 quits but reports
run-time error R6001
- null pointer assignment

Tried Scream Tracker 2.2 and 2.3 in MartyPC (new_ega branch, commit: a189d6e).
Machine: 5150, 82OCT27 ROM, 640K RAM, CGA
OS: MS-DOS 2.11
ST 2.2 start to the main screen, and hangs when quiting. ST 2.3 cause CPU halted as your screenshot.

"[ISA] CGA"

Tried Scream Tracker 2.2 and 2.3 in PCE (5150, 82OCT27 ROM, 8088, CGA, 640K RAM, PC-DOS 3.30). Both version start to the main screen. Then ST 2.2 hangs when quiting. And ST 2.3 quits but reports run-time error R6001 - null pointer assignment

As for that, I know that happens when you don't configure the folders the Scream Tracker 2 is expecting (STINS99, STINS, ADD, and SONG being in the ST (called "System") folder) so as far as I'm concerned I'm not worried about the run-time error

Tried Scream Tracker 2.2 and 2.3 in 86Box 4.0.1
Machine: 5150, 82OCT27 ROM, 8088, 640K RAM, CGA
OS: PC-DOS 3.30
Same behaviour like in PCE.

I don't know this software. Just a test.

Maybe run on specific configurations. Not sure.

ST 2.2 and 2.3 in PCem v17 behaviour the same like in PCE and 86Box.
ST 2.2 in PCjs (5160, 82NOV08 ROM, 8088, CGA, 640K RAM, PC-DOS 3.30) runs, and writes trash characters after quiting. ST 2.3 in PCjs cause CPU halted. Undefined opcode 0xFF at 0x000F360E
