The game works without forcing VESA in 0.72 (which does have S3 emulation). This CRTC detection code is used: mov dx,03d4h mov ax,4838h out dx,ax ; write 0x48 to index 0x38 (Reg lock 1) mov ax,0a539h out dx,ax ; write 0xa5 to index 0x39 (Reg lock 2) mov al,47h out dx,ax ; write 0xa5 to index 0x47 ( …

You do realize you have to change the machine type in the conf file and restart DOSBox? just typing "machine=svga_et4000" at the prompt doesn't actually switch to the other machine type. If I didn't spell it out clearly enough, type "scream vesa" to run with forced VESA.

The game is either mis-detecting the S3 chipset, or not using it in a way that is compatible with DOSBox. However, machine=svga_et4000 or machine=svga_paradise works OK. If using machine=svga_s3, the game works if you force the use of VESA by adding a command-line parameter of "vesa". The issue is …

I've read that some gfx corruption can occur in the game unless you use machine=vesa_oldvbe, but that might refer to something more severe than the trail artifacts you're asking about. Are you sure the artifacts don't occur on real hardware? Perhaps system performance is a factor: the game might …

Machine type can't be changed on-the-fly, it's locked into what is in the config at startup. However, you can change the setting inside DOSBox, and write it to a config file if you choose.

There is a known issue with the installer for T7G that should be addressed in the next version, as Qbix pointed out. In 0.73 you can do a "loadfix -f" command before running the installer, which should prevent it from getting stuck.

If you mean the volume serial number for mounted drives in DOSBox, try 0000-1234; but no guarantees since it isn't fully supported.

Appears to work OK with machine=svga_et4000 and machine=svga_paradise in the DOSBox conf file. With machine=svga_s3, run the game like "wsim /v" to force VESA. Might be interesting to know if it's correctly detecting and then using the S3 chipset.

Things don't usually go bad by themselves. Try this: rename your .conf file so DOSBox will use a default config, and you'll also have a backup of the current settings. If the default config works (it should because I don't have the problem you describe) then maybe you can try to determine what …

BTW, the pitch of the sound in the program changes with more or less cycles. Around 375 cycles seems to give normal pitch.

It's not that it expects background noise, it expects the SB to respond with the sound level, but DOSBox currently ignores the request. The hacked driver, and the proposed patch, simulate silence or no mic plugged in. Because the silence level is always below the program's lowest threshold, it will …

Based on the version of the program here , I hacked the driver file to make the program think it's hearing nothing. It won't respond to sound, but the parrot will randomly say things, and you can press keys to make it talk. If the DOSBox devs will consider it, one of the DSP commands can be …

For DOS you don't really need anything fancier than good ol' DEBUG.EXE to dump a BIOS image, unless you're looking for something a little more user-friendly. Start up the DOS debugger and enter these lines, pressing ENTER after each one: r cs c000 r cx 8000 n video.rom w 0 q That will work for *most …

I tried Tracon II 2.01 with the P800 mode (that version doesn't have a 1024x768 mode for Paradise) and get the same result. Looks like a "flood fill" operation on the plane silhouette is not staying inside the border. Edit: the problem happens because the game calls INT 10/AH=0Dh to get the color of …

Clicking the scroll wheel on my mouse is recognized as the 3rd button in DOSBox. I tried King's Quest 5, and the 3rd button does cause the mouse pointer to revert to the walking icon. What OS are you having the problem with? Maybe there is an SDL issue on your platform...

Only the devs know for sure, but I think the delay is to keep it from excessively turning on and off, which would be inefficient and there is sometimes a popping sound that occurs at on/off. 30 seconds was probably chosen for being long enough, but not too long. The PC speaker emulation uses a 10 …

I was reminded of this issue from a recent thread ; and since the OPL code has changed quite a bit since 0.72, I thought I'd make an updated patch for current source (also works with 0.73 release source). The idea remains the same: only shut off the FM sound generation after 30 seconds if none of …
