Internet / Re: Problems with OpenSSL library after update.
« Last post by Steven Levine on January 29, 2026, 04:21:18 am »
The updated exceptq report helps a lot.  I'm going to chalk this trap up to bad luck.  Here's what I suspect is
happening.  We are trying to execute

 vmovdqa ymm7, [rbx+40h]

and exceptq tells us that

 EBX : read/exec  memory at 0001:00148930 in CRYPTO11

which confirms that ebx+40 is not properly aligned.  It also tells us that ebx is probably pointing at constant data stored in the code segment - possibly OPENSSL_ia32cap_P.  A copy of poly1305-x86.s would make this easier
to figure this out.

IAC, whatever the data is, it's now in an unaligned location in 1.1.1w.

To avoid this, we would need to figure out how to ensure the data is aligned and change to code to use vmovdqu rather than vmovdqa.

Hello

Does anybody knows how to use an Apple I ?? just to see if this emulator works.

http://apple1.chez.com/Apple1project/Emulation/Pom1-0.70b-JAVA.tar.gz

It runs with "java -DECHO="N" -DROMFILE="6502.rom.bin" -cp Pom1.jar pom1.Exec"
, but I'm not sure if it works fine.

regards

It seems to be a local problem. I should probably uninstall and reinstall cmake.
Often I can work around by using Ninja instead of make but am unsure how to add extra includes and libraries as we're using the OW SDL libs.

Been having problems with cmake, it produces makefiles that recurse and lock the system up.
Do you think it is an issue with out cmake port? or some configuration change on your dev enviroment?

Hello Dave

Did you have any luck with the "snakeme" source code?

Games / Re: DTA (DTAudio) and DOS Sound Blaster audio
« Last post by Roderick Klein on January 27, 2026, 08:06:43 pm »
Hello

Roderick is working hard to try to find a ASM developer to help on the "DOS VDM - Sound Blaster audio" support. (DTAudio).

I also support him, since I also want to have the audio under DOS VDM to complete the "Retro-Gaming Machine" !

Here are some link that would be nice to share with developer that may want to help.

Code: [Select]
VDD source code sample
- https://github.com/OS2World/DRV-VDDs-GoSierra
- https://github.com/OS2World/DEV-SAMPLES-DRV-DEMODD

There are some Assembly projects that may provide some inspiration:

VSB - Virtual Sound Blaster  and TEMU
- https://github.com/volkertb/temu-vsb
- http://ericauer.cosmodata.virtuaserver.com.br/soft/by-others/dos-virtual-soundblaster--vsb202.zip
- http://ericauer.cosmodata.virtuaserver.com.br/soft/by-others/dos-virtual-sound-blaster--vsb-src.zip

VSBHDA - Sound Blaster emulation for DOS
- https://github.com/Baron-von-Riedesel/VSBHDA

Any other VDD source code samples that you may know?

Regards

Most likely the developer will need to use a DDK possibly to compile these sources from Martin Kiewitz as the IBM DDK has some LIB files that might be needed and header files.
But I am not certain. Also most of these sound blaster emulators might not even offer what we need. This all comes from my memory from about 20 years ago. So I could get it wrong.

From what i recall the main vsound.sys should be working to emulate a soundblaster 16/Pro or Soundblaster. I have never been able to even get a compiled VSOUND.SYS to work and show a soundblaster card in a DOS game. From what I recall vsound.sys already should emulate a Soundblaster 16 (only audio, no OPL3 yet).

Vsound.sys is client driver that talks to DTA.SYS. But the older version of the DTA.SYS that we have might not work. I do not know.

But somebody will also have to look at VCOMPAT.SYS and VDMA.SYS so everything works inside the VM. So its much more complicated puzzle.
And knowledde of x86 assembly will be very handy.

Hello

Any idea what this program is?

Is it the "Anthy -- Japanese Kana-Kanji Conversion Engine Library" ?
https://github.com/netsphere-labs/anthy

Seems to be, tried building the git version,
Code: [Select]
Directory of H:\tmp\anthy\src-util

 1-26-26  7:45p        48,204      0 a---  anthy-agent.exe
 1-26-26  7:44p        37,738      0 a---  anthy-dic-tool.exe
 1-26-26  7:45p        40,169      0 a---  anthy-morphological-analyzer.exe
Unluckily the git version uses UTF8.

how do we know if it works?
Almost seems like something is missing,
Code: [Select]
H:\anthy\bin>anthy-agent.exe
Failed to init anthy
Or perhaps I don't know how to run it. Need a Japanese user I guess.

Unluckily the build dies, needs some -L and -l added to the configure LDFLAGS and LIBS to fix some missing symbols.
Edit: fix a typo

Played around with the drive icons in the trunk\dll\icons.

just something to look at.
