It seems DOOM and WARCRAFT work well with TSR loaded, but DISNEY’s LionKing and TOMB RAIDER don’t work even if there is setupds loaded only. Is there any solution?

Its working fine with analog?

I don’t think so. It seems the problem has no relationship with YMF7xx.
After DOS4GW information being printed, I get a black screen.

In that case, there are bettter thread for that, this is about digital sound output.

Both games are working for me on Yamaha 7x4 for me, for details look at this list:

As CMI-8338 is very hard to obtain nowadays, I think then it could be reasonable to do some experiments with PCI CMI-8738. (This would possibly also easen the ISA saturation problem). I guess I'll order one on ebay and report back when I did my experiments.

A Russian seller on the Bay got four CMI8330 based AV310 cards for sale.

Big thanks for the hint! 😀 😀
When I read that, I looked at ebay quickly. Only two cards were left. I instantly grabbed one. Now there's only one left.
Will report back testing results when card arrived.

Sorry, got it.
I could get pretty good digital sound from the SPDIF, with a similar feeling like what I got from the emulators like Nuked OPL, but the analog output sounds brighter (weaker bass). I think the SPDIF output is closer to the original OPL3 sound. Am I correct? Is this kind of special analog sound caused by the ST DAC or the onboard amplifier ST2025B? I set the jumper to LINE OUT.

since today we received the v1.0 PCBs I thought it was about time to reveal what marmes sacrificed his evenings for 🤣 🤣 🤣

NQco2e7l.jpg

- it has SPDIF output that works transparently like the analog output
- it has a real OPL3 and is SBPRO/WSS compatible
- there is an optional mpu midi interface based on PCMIDI (if installed the soundcard uart mpu gets disabled completely)
- it's a 4-layer design - final version will be a little different but core features are the same
- just in case you were wondering about the card's name: https://en.wikipedia.org/wiki/Orpheus

more details after testing , wish us luck! 😊

Fancy ! So many sound cards lately haha
Is it based on a Crystal chip ? Pinouts don't look like something I can immediately recognize.

^ hey give us some time for all the parts to arrive and do a little test that ensures the thing works as expected 🤣
I will make a dedicated thread then with all questions answered 😀
Tiido don't expect fancy stuff like you do on your cards with custom drivers etc 😀 - this was designed to be just a good sbp/wss card for some retro gaming with optional smartie-pants midi interface and working with the stock initialization program for the chipset.

This looks cool. Some questions:

- Is it MPU-401 Intelligent Mode compatible?
- Can you output both OPL3 and sound effects through SPDIF?
- Any limits to sample rates for SPDIF?

Good luck with the project!

if the mpu part is populated then it's the same as the PCMIDI cards marmes and me are selling so it's intelligent

j^aws wrote:

yes that was the point. The main chip provides among other things digital and analog mixers, DAC, ADC ... so all sources of audio will be outputted through spdif at 48khz 16bit max which is what the chipset natively supports.

Hey keropi! Your sound card project looks very interesting and I'd like to see this get on IndieGoGo or some other fundraising site if you want to generate some noise (no pun intended) around your project.

I think an awesome addition to your card would be the inclusion of high quality Japanese solid state capacitors and improved filtering, so that the noise floor isn't anything like old Sound Blasters of the day as well as a means to eliminate any ISA bus noise. I realize over SPDIF this is mostly unnecessary, but for those stuck with analog setups, it would be ideal to keep the quality crisp and clean on that front as well.

Would one be able to configure both SBPRO and WSS modes to work at the same time? i.e. I don't have to change modes in a control panel and reboot to toggle between SBPRO and WSS modes.

Hey mattrock1988
card is a 4-layer design with nichicon muse caps so don't worry about the analog side 😀
there is no need to reboot or chose anything for sbpro/wss modes - both are available at the same time - ofcourse only 1 can be used at the time
marmes and me are on the final test stages - software took more time than expected...

well here is a photo of how the prototype cards look populated - as expected some patching was needed.

MqB8I9xl.jpg

This is almost complete - only testing from other people is left to be done.
The card works with the stock CS4237 drivers and there is now a small software to activate spdif output under dos (under win9x it's a driver option, way easier 🤣 but the main target of that card is DOS and not windows)
The mpu part (if populated) is based on pcmidi so it just works. SPDIF output is fixed at 44.1khz , the discrete OPL3 used is the YMF289.
For now testing will be done with cards that have only the soundard part populated + patch wires, 4layer pcbs are not that cheap to just scrap 😵

So, the sound card has the same MIDI as the Music Quest MPU401 card and a Wavetable header? Very interesting.
