I have to say that I'm using the disk quite a lot on VMs, mainly for "VBSF" (VirtualBox Shared Folders) but some of the other tools came in handy too.

What an adventure 😁 Did you manage to save a copy of an infected file? I see a "Junkie" in some DOS virus collection but who knows if it's the same one.

I've determined the cause of silent audio in Doom and Dope reported by @Pickle and @HandOfFate, and I have a firmware fix! Many thanks to them for sending the cards back to me. At first I thought it was due to shipping damage or chipset incompatibility, but in this latest batch of cards I just made …

I think Maabus also required it. I don't know why I remember that game, at all, but the name conjures up images of Quicktime to me and Mobygames backs my memory: "Maabus uses three CD's worth of Quick-Time Video clips to generate scene transitions as you pilot an automated tank across the …

Possible license issues aside, it's an impressive collection of features for the size. Did you use any tricks to save on space?

I see a few versions of an Eletronic Workbench on Vetusware, and does seem to be a Win 3.x program (but version 5 needs Win32s to run)

Thank you, that is a good suggestion. Definitely worth a try. I am familiar with OpenBioforge. In a sense I could just wait for that to be released since that will likely be way before I have enough done to even resemble a game. But I guess I will just use my own project as a fun learning …

Avast kept its AntiVirus program for DOS up to date until 2004 or so. Don't know what the minimum DOS version is that it requires. I don't think I can link it here but it's easy to find. The version number was 7.70. In any case, should you find something it would be nice if you can keep a copy of …

Another newbie DOS reverse enginerer here: I recently used the MEMDUMPBIN command in the DOSBox debugger to get around the obfuscation of a program. Its code was stored in fragments in the binary and placed at the correct positions in memory at runtime. I dumped everything once the de-obfuscation …

I have an OG xbox that has a stuck DVD-ROM tray, I can only open it with a pin through the emergency eject hole. I'd guess the belt went bad? Is that an easy repair with these machines? If you haven't yet, do consider softmodding your Xbox now. You need a working DVD drive to do that and without ( …

This makes sense and also makes me curious. Is there a main limit as to why the PicoGUS is a 3.3v device and isn't driving at 5v? The RP2040 has 3.3v IO, and I didn't want to add an extra bus transceiver chip to convert up from 3.3V to 5V. If there are no conflicts (and to be quite honest, no card …

What does the process of switching modes look like? I see references to "when X firmware is loaded" in the wiki and on the git page. Is switching modes, say from GUS to MPU ,as simple as running a command and then launching an app? i set up some batch files to make it quicker, but all you have to …

I have been testing the 366MHz firmware that polpo sent me and while most games seem to be more consistent, Doom and Dope ( download link ) are still troublesome. Dope in particular has been difficult. Not only did I only get to work once (with the original firmware), in my latest test it also …

Interesting, I'm 99% sure I don't have an IRQ conflict in either machine (I also marked IRQ 5 as "already taken" in the PNP BIOS settings and I know the VGA card in the 486 is on IRQ 11) but I will double check later. Did you happen to have a view of the LED on the card when the games were silent? …

Looking forward to trying it out, polpo! Because my 486's chipset reportedly has issues with flashing the firmware I pulled another machine out of storage in anticipation of the updated firmware. This is a Pentium II with a Intel 440BX chipset and the card has the same symptoms as on the 486, so …
