A small heads up (also since @Tiido has mentioned a few issues with the previous build in a different thread), there's a new maintenance build available on github that among other things fixes issues Tartar had with Sigil II demo playback.

Thanks to the mod for splitting this out. Ok, so firstly - Hexen and Doom/BOOM are not equal in how the renderer works, so while one could draw similarities, I would say this is an apples/oranges situation, and one could as much compare, say, Duke 3D (why not?) and Doom. While Hexen adapts quite …

Sorry, while I must have downloaded the utility a while ago, I did not realize I could use it to change memory mapped registers. Here's SBEMU driver code bit that updates the one. Let me check if I can use YMF7XX for the same purpose - could be much more manageable/scriptable in the end. EDIT: I …

Can you let know which shader you are using? I am now curious why it would make the picture look better with the horizontal "pillars" of 640x480 resolution. I am also fiddling with RetroArch on my PC now, so could check that in action.

My experience with RetroArch is only quite recent, as I am using it with my handheld device and there I found DOSBox Pure core to be the most agreable one. The feature of *Pure is that is does not perform aspect ratio conversion or scaling on its own, relying on the frontend for this. There I use …

Apologies for crashes your are experiencing, but nah... Tartar follows the MBF path, and should prefer 640x400 to 640x480 when both are availabe; there's no override for this. If you could stand compiling either - I trust instructions can be found in this thread, especially if you try following @ …

So, eventually I was able to make a utility that unmutes SPDIF in using SBEMU as a basis. The only thing required, it seems, was sending a 1 to a DSXG register's memory address offset 0x34 (SBEMU sent 0 by the way). My being a lazy coder, I simply reused SBEMU YMF initialization code for the purpose …

A quick update on the YMF topic I raised above - looking at the driver code I was able to locate the bit that enables Digital in. Was in DSXG proprietary register, not standard AC97. Many thanks to @crazii and contributors for doing all the hard work 😀

Sorry if it appears I am spamming (as I've asked about similar topic in the card specific thread already), but would YMF7xx cards support also mean ability to control via AC97 interface the state of the input/output lines? I am curious if unmuting certain input line would be possible using SBEMU …

In Windows 98 I can hear music when I simply press the hardware play button on the drive front panel, provided the Digital In is unmuted as per @Joseph_Joestar …

Apologies if I am asking a dumb thing, but how exactly does Digital CD Audio input work? Is this just one of the available CD Audio inputs the card has, or is there anything special about how it is used (e.g. some special command to the CD-ROM to actually output audio in digital format, or do both …

Hey, thanks for reporting that oversight - cheat codes handling was never updated to take extra defined episodes into account! Now the reason is that I almost never use IDCLEV and instead do, e.g. MAP E6M5 from the console (opens with the [~] key). Also acknowledging additional demo information. WRT …

@Tiido, apologies you are not getting working game by simply following the readme. I will review it. From what I can see shims get loaded for you - they actually contain the definition of the episodes for them to be visible in the menu. Can you try this: https://www.moddb.com/mods/tartar/news/ …

I could use it with Sakitoshi's mbf_sigil but it has one major problem which is lack of WSS support. So I wonder what would it take to get the new episode work in the "regular" version that does have WSS support ? You might as well try Tartar - it is using the set of sound and video routines from …

You put the patch into your game directory on a DOS machine (e.g. in DOSBox), make a backup of your game, then run the patch. PatchMaker thread is actually one of the pinned topics in a neighbor subforum. I decided to be not lazy and produced a Doom II patch that honors what weapons the player …
