That happens when your ROM BIOS does not have the standard 8x8 font stored at F000:FA6E.

Why can't you all see it, why write a same absurdity about FM, MT-32, version 1.3? Foolishness. The only absurd fool is you, who is too foolish to understand that my comment about version 1.3 was a response to badmojo, not to you or Hevy, even though I correctly addressed it by putting his name in …

Prince of Persia is FM only from memory so you can’t change that That is only true for versions 1.0 and 1.1. Version 1.3 adds Roland MT-32 music. Anyone know how to run 2 cards at once with 1 set of speakers? Connect the Line-Out output of one card to the Line-In input of the other card, then use …

More importantly, the hiss I described is unrelated to the actual signal, as it occurs even if the DSP is playing back a signal containing only $80 samples.
Re: The "12-bit" Sound Blaster 16 Myth
Posted on 2019-05-11, 08:38
I have only two 16-bit sound cards from Creative: a early-ish (DSP version 4.05 instead of 4.04) Sound Blaster 16 "ASP" (CT1740), and a late-edition Sound Blaster AWE 64 Gold (CT4540). I was always very dissatisfied with the CT1740's DOS game sound quality for two reasons: audible clicks during …
Re: Jill of the Jungle Sound Effects
Posted on 2019-05-09, 21:53
Remember that version 1.2b replaced DMA-driven PCM playback with timer-based BBAB ("byte by agonizing byte") sample writes, so they had to accomodate two simultaneous timer services at different rates to do that. I question whether that is something to implement in v1.2d patched though. The only …

Do not use full quotes when responding. I don't know what exactly "it" is that is supposed to work on the Vibra 16 CT4170, but it will not be "Jill of the Jingle" with "Do you want digital sound?" answered "No" and "Do you want the musical sound track?" answered "Yes" producing music and PC speaker …
Re: The myth of the vertical retrace interrupt on EGA/VGA
Posted on 2019-03-01, 13:25
Your explanation about the edge- vs. level-triggered interrupts sounds very plausible to me. Clone makers might have lazily thought that for ISA cards, they can save a few bucks by not implementing the feature when even IBM did not implement it either. If your program does not run well with the EGA, …
Re: The myth of the vertical retrace interrupt on EGA/VGA

I missed this topic when it was originally posted last year, but let me add the following: The VGA chipset's vertical retrace interrupt apparently was implemented on all IBM PS/2 machines that had the VGA chipset on-board. When IBM released the VGA chipset as an ISA bus card, under the confusing …
Re: Wing Commander II with MT-32 gives wrong sound effects
Posted on 2019-02-27, 19:46
Sounds like the custom timbres are reaching the MT-32 only partially. It cannot be that the custom timbre transfer has failed completely, because one of the explosion sound effects at the end of the Origin FX logo sequence is played, and when the Wing Commander II logo appears. You did not mention …
Re: Games that show 16 colors ONLY in Tandy / PCjr mode?
Posted on 2019-02-24, 15:19
Tandy has composite output, doesn't it? Only the earlier models do. The SL, TL, and RL ones do not. And the ones that do have a different phase offset than the CGA, so the colors of composite CGA look wrong and would need to be reassigned. Generally, the composite output was largely unused by Tandy …

Not with 320x200x16 color graphics, just with CGA-composite-displayed-as-RGB graphics. So it works, but not "well". 😢

Re: Games that show 16 colors ONLY in Tandy / PCjr mode?
Posted on 2019-02-23, 20:12
No, I cooked it up myself. Nobody used it for anything, likely because it's a hit-and-miss between VGA cards. I have successfully tried it on the Matrix Millennium G200 and the Trident TVGA 8900. The Matrox required using the Data Rotate register, while the Trident did not. It did not work at all on …
Re: Games that show 16 colors ONLY in Tandy / PCjr mode?
Posted on 2019-02-23, 08:00
PCjr uses a remapping scheme, where the B8000h-area is mapped to a 32k block in the first 128k (the last block by default). The Tandy 1000 does that. Unfortunately, the PCjr only maps 16 KiB to B8000h, so one has to use the 10000h/18000h area directly for 320x200x16 color mode. Many VGA cards allow …

I forgot two parameters that only exist in early SCI1 games: -f: Search for RESOURCE.00x files on all drives instead of just the current drive. To be used with the "Small Install" option in the INSTALL program that just copies the "Startup" disk to hard disk and then prompts you to insert the other …
