I completely forgot about the ImpulseTracker! This is an excellent music tracker, the source code of which is open, so I can easy make support for CMS/GameBlaster output now. I again took the driver for audio output on LPT Covox as a basis and changed it a little. As a result, we got the CMS.DRV …

Just curious, how large are the .wav files you played, and what are the rest of the specs of the computer you did this on? I wonder how slow of a PC could actually handle this. I am very lazy to write my own player for WAV files, so I took someone's ready-made code in Turbo Pascal and changed the …

SAA output should be logarithmic as is AY and the Ti PSG. I dont think so. If you take a look at my first post on this topic, the picture, you can see that the voltages decrease linearly depending on the volume: vol 0 -> vout 5,12V vol 2 -> vout 5,09V vol 4 -> vout 5,04V vol 6 -> vout 5,00V etc.. …

I found a STM/MOD player with an open driver architecture with source codes - http://www.dcee.net/Files/Music/Player/ (play382.arj) [Sound Wave Pro / FRIENDS software / Andrew Zabolotny] , so i modify a little COVOX.ASM and play few STM and MOD files over Creative Music System / Game Blaster... …

Hello, I found outdated similar thread on pouet.net but unfortunately it is outdated.

I did a little research with a multimeter: P113092.JPG X-axis is the amplitude of 05 …

Has this also been done yet for the Innovation SSI-2001 card? (It's a PC sound card with a Commodore SID chip that saw very little support in games back in the day, even less than CMS.) Probably yes, but I don't have SSI-2001.... So far I have made CMS/Game Blaster support in the DOSMid player . …

possible candidates in my opinion: 1) 74LS245 - buffer between ISA data bus and SB data bus; 2) Crystal oscilator, crystal generator 3) main SB chip

Recently I thought - that if i take the source codes of SoftMPU, modify them a little so that there is internal processing of midi commands and output of frequency and octave to the hardware port of cms. I thought this would allow games like Doom or Duke3d to run with "general midi" device selected …

It would be great to develope something like a SoftMPU to just select General MIDI as music output device in games for original CMS/Game blaster on port 220h and CMSLPT on LPT port... Hook a 330h/331h ports and convert "on the fly" MIDI messages or MIDI notes to SAA1099 synths commands like this …

For the successful operation of this video card, it is necessary to set the jumpers correctly (because they physically connect some memory lines). Here is a description of the jumpers: https://stason.org/TULARC/pc/graphics-cards/U-Z/UNIDENTIFIED-XVGA-S3-805.html So, you need set JP5 1-2 and JP4 2-3.

ok, reconfigured the card to 330 (was on pnp before and ewsinit always assigned it to 300 then) and it actually worked with just -f, but i still did the init as you said. i'll send you the dump file, looks like there is still mostly garbage from 0x100000 on though... Thank you very much. …

put my 1.2 card in, ran ewsinit -f in DOS and then your tool, but i only get some "ERROR get ack!" messages. there is a dump file but i guess its useless then, does your tool expect the card at a certain address or something? and btw, since you mention it writing data i hope there is no chance of …

Hi, Ar2r4eg gave this EWS64 board to me for diagnostics. So, what i tried to do: - found out that the signal when playing wavetable MIDI originates from the SAM9407 chip in the form of a digital line I2S (Philips serial protocol for audio), specifically from pin 48 - DABD1 (data). Also, with SAM9407 …
