r12 is now ready. No new features, just bug fixes. All versions of VIDE-CDD.SYS should now work and the broken -dsp command line parameter now works again but stereo channels are still swapped. There does not seem to be any easy fix for it but I'll try.

I have Nexus NX-4090 that is supposed to be unused and I believe it since it had no dust at all and looks very clean. I was going to use it as AT power supply replacement but turns out it has that yellow glue. I assume it it the same that eventually turns brown. Since this is old but unused, the …

I unlocked two 570ACZ CPUs and tested the first one. Looks very promising. I used MX4 between core and heat spreader and MX4 seems to be just fine. I glued the heat spreader back with Sikaflex 112 Crystal Clear (I just happened to have that already). First I run memtest testing the cache only @ …

There is nothing wrong with the CMI8330 but for example the CS4237 does sound better. So when comparing to Orpheus, you get SB16 support at the expense of sound quality? That would mean that if you have GUS, then Orpheus would be better for Sound Blaster stuff since there is very little, if any, …

Looks very promising! I definitely want one with the addon card. Those features makes it one of the best Sound Blaster clones but the addon card should have had one extra OPL so dual OPL would have been possible with single card.

For those having problems with VIDE-CDD.SYS, please try v2.14a from here . I think 2.15 is the one having the problem. Edit: Also found and tested versions 1.11, 2.00 and 2.10. They are even worse than 2.15. They either freeze or reboot the computer. So use the v2.14a. It is the only one that works. …

I had to compare myself and it seems to be true. SB Pro 2 stereo is correct on that Panic demo but reversed with Midito r9 (and CT2940). I don't know why. Sound Blaster Series Hardware Programming Guide (from 1996) tells that left channel byte starts 8-bit stereo sample and then comes right byte. …

I too have noticed the problem with VIDECDD.SYS. I don't know what causes it. Maybe VIDECDD.SYS traps ports for some reason but I did test loading it before and after EMM386.EXE and there was no difference. If it traps ports, then it must do so during/after loading MSCDEX. But more likely it is some …

It seems that the -dsp is broken in r11 (and likely in r10, I didn't test it) but works in r9. I tested Seconds Reality and it works with r9 and so does Scream Tracker. Impulse tracker works at first but eventually fails after playing more modules. I think I know why but first I need to fix r11.

Maybe I broke something on r10 or r11. Sounds like stereo bit is ignored. Do you use only -dsp or maybe -fm or -lock as well? They all need to trap mixer so it is possible that only some combination is broken. I've mostly tested with Aladdin so that is one game that should definitely work and stereo …

I was wondering if it would be possible to solve the very very niche use case of making the DOS demo Crystal Dream by Triton work on SB16 sound cards. I can try but it is possible that changing the busy bit to behave like SB pro will break some SB16 code instead. That SB16 busy cycle could perhaps …

Release 11 is ready. It has fixes for r10 FM problems. It is now possible to override the SET BLASTER card with -sb=a# command line parameter. For example if SET BLASTER points to A220 but you want to trap card at A240 instead, then just use -sb=a240. MIDIto will detect the card type but if you use …

I somehow didn't even think the possibility that Line-IN mixer mode needs to work when SET BLASTER card is the one connected to another Sound Blaster cards Line-IN. Looks like some way to select the card is needed so I'll see what I can do. But since both are Sound Blaster Pro compatible, they …

Release 10 is mostly about FM redirection and related things but there is one Midi related change: when redirecting midi you now have to use …

I made one more recording (same link as before). This time from Cycles (Adlib game) but now CT2940 with real OPL3 plays left and YMF right channel. Sounds much better than the CQM+YMF combo. YMF does have little lower volume than the CT2940. It is very hard to adjust them to be equal.

I managed to find two more CT2940 cards and one CT3600. They all have the CT2502 "Vibra Pro" chip and I wanted to test if any of them have the clipping bug since my previous CT2940 did not have that bug. I'm a bit disappointed because none of them has the Vibra clipping bug. I should be happy about …

No reverb or chorus was added to AWE64. I need to test with two same kind of cards. If the reverb was caused by differences between CQM and OPL3, then it might be possible to fix it with software delay loop. Another alternative is that it was caused by EMM386. I don't know how directly it outputs …

The interesting thing about them is that left channel is played with AWE64 (CQM) and right channel if played with …
