You aren't the only one.

I'm hit with the same symptoms with the floppy version as the CD one, which seems not to be the case with what's going on in that other thread.

Does the video glitches when there is no sound configured?

Feels like some kind of synchronization problem.

Ok, now I'm super baffled. I copied the files to my 2nd Vortex86DX unit and......everything works flawlessly. I wish I could understand what's going on! The only difference is the media I'm using as a hard disk. They're slightly different SanDisk microsd cards....

edit - 2nd difference, I didn't install the game, merely copied the contents of an already installed game.

I'm back to a glitchy version after trying my luck with the patched .exe that adds MT-32 support to the CD version.

I'm curious about this. Does the BIOS settings and versions are exactly the same between the two Vortex86DX?

everything is exactly the same.

edit - no sound configured, I still have to figure out how to make it happen. The install utility doesn't give that option. I must blind-guess what to write in the resource.cfg.

Strange. As for why DOSBox doesn't have any issues in that game is due to the emulator hiding and addressing some of the issues that only occurs on real machines such as I/O delays.

Some BIOSes have an option to set the I/O wait states or something similar where increasing them could help with your situation.

Retracing the file copy steps, back to glitchiness. Something else escapes me.

Soutbridge ISA Configuration

ISA Clock is at 8.3 MHz (at lowest setting already)
DMA operating clock at 4 MHz (lowest setting already)

ISA 16 bits I/O wait-state: switched 1 clock cycle to 4
ISA 8 bits I/O wait-state: switched 4 clock cycles to 6
ISA 16 bits Memory wait-state: switch 1 clock to 4
ISA 8 bits Memory wait-state: switched 4 clocks to 6

it still glitches

I then tried 8 clock cycles everywhere (except 16 bits mem to 7), with L1+L2 @ 800 and without L1+L2 @ 25 MHz, still glitches.

Have an interesting idea here that we haven't checked here before, can you try to run with EMM386 in CONFIG.SYS?

I recall that some games didn't work well without any expanded memory manager even if the game doesn't require EMS.

Wow. This is WILD. Despite expanded memory being my default configuration out of 9 in my autoexec.bat, I managed to always select conventional or extended memory in ALL my tests. I've tried running it with your suggestion twice, works. I tried rebooting, works.

Let's see the 486 now?
works.

thanks!
A fix so basic it could not have been it at the start!!!

You're welcome!

Ooh!

I can also confirm configuring EMM386 for EMS also fixes it on PCem (addressing last year's thread reply)

(though...there's older EMM386 versions which Willy won't play with due to DMA reasons. DOS 6.22's will be fine though)
