The DOSBox-X discord came to rescue. I have to use log ffffff to log lots of instructions, and with it I got a 500mb file I used to find the startup sequence of CauseWay at line one million and change. The startup sequence has an evil loop for about 40k instructions, but my editor is up to the task …

The source code of CauseWay extender is here: https://github.com/amindlost/cw I'm part of a team who works on this project, in order to reverse-enginneer real-mode programs (which offers also a GDB server) : https://github.com/OpenRakis/Spice86 CauseWay extender MIGHT run with it. Emulation-wise, …

I was trying to use DOSBox-X to debug a program [1] but when I used the log command to create a CPU trace, all it does is create an empty LOGCPU.TXT file, and no trace is generated. I am using the latest provided DOSBox-X binary, that I know of; specifically dosbox-x-vsbuild-win64-20221226190454.zip …

Hi, I don't know what Aztech PCI 368 Thunderbird is, but we can have drivers. https://archive.org/details/aztech368.7z

Thanks, though neither of the sellers will ship to my country, but yes; there are chips floating around. Are these Voodoo 4 chips, and not Voodoo 5? Where can I learn more about free floating chips?

Out of sheer curiosity, I wonder if there are still any spare 3Dfx chips left? I don't know exactly what happened when 3Dfx got bankrupt and was sold to Nvidia, but I imagine at least some chips were being fabricated that never ended up in a card. Do we know if my imagination is true or false? Are …

Not only is it one of the early buggy 386s Every non-SX 386 from Intel without the double sigma marking should be seen as buggy and safe for 16-bit software only. Out of curiosity, can software detect these buggy CPUs somehow? I see the above PCjs blog has all the software tests to identify these …

Anyway, I don't fully get the question. Whether a controller is a game pad, a joystick, or an arcade stick, makes no difference. They all use the game port in the same way. And DOS of course is not relevant for this either, as the game port works in DOS just like it works in Windows. (proprietary " …

What were the arcade sticks made for DOS, if any? A quick websearch doesn't reveal anything from the DOS era. I was never really a DOS gamer, so I have no recollection of the period correct hardware, and I don't know what brand names to look for. Specifically, what I'm interested in, are pictures …

Ok, so I got interested in poking 3Dfx Voodoo cards programmatically without drivers. So far I'm working with the Voodoo 1 emulation in DOSBox, but later on I intend to collect and experiment with real physical cards. One thing is that to properly set up the Voodoo card, I need to query and/or …
