You have to place dgVoodoo DLLs and config file both on the root directory, and inside the "MUSASHI" folder. If you place them only on the root folder they are ignored. Placing them only on the "MUSASHI" folder throws and initialization error.

Thank you @BEEN_Nath_58! With this patched AYAPI.DLL the game (DD1, not 2) now works great using dgVoodoo on Windows 10 (it crashed before). It still requires some sort of exception handling, as the executable contains privileged instructions (I noped that instructions, instead).

I made a DOS 6.22 install on DOSBox with 512,63,255,1024 geometry and it worked fine. Using a size that large is definitely asking for trouble - as I mentioned earlier, DOSBox uses regular buffered file I/O functions (fseek, ftell, fread, etc.) which do not handle file offsets larger than 2GB. Any …

So, 'an actually 2GiB volume' has an ECHS geometry of 512, 32,128,1024 There are very valid reasons for not wanting to have exactly the max cyl count. The most valid reason is that 1024 doesn't fit in 10 bits, making it an invalid value. 1024 cylinders, numbered from 0 to 1023, should fit on 10 …

The geometry used by DOSBox is defined at INT13 BIOS level, not IDE level, so the following limits must be respected: C <= 1024 H <= 256 (255 for DOS compatibility) S <= 63 BPS = 512 You can use any geometry you want, as long as these limits are respected, it will work. For generating the image with …

Yes, the problem is the 512kb S ROM. Same thing happens on the Vortex modified Chinese 161-in-1 multicart, as it only supports 128kb S ROMs. For other games with 512kb S ROMs there are patched bootlegs that make it work with only 128kb, but for KOF2000 seems to be impossible. There are some …

I tested it on DOSBox-X in glide pass-trough mode with nGlide and dgVoodoo, and in Voodoo emulation mode, also tested it on PCem with Voodoo 1 emulation. In all cases I get the same flickering text (although not as severe as your video), so it seems to be a bug on the game itself. Would be nice to …

A K6-2+ is quite a bit overkill for this game, that suffers from the typical fast CPU issues, even with caches disabled. What frequency are you running that CPU at? Beside disabling caches, can you try lowering the CPU multiplier?

If you are sure you only need ARP.EXE, you can extract an updated version from the WinSock 2 Windows 95 Update. It's a free update distributed by Microsoft back then, so I think it's OK to upload it here. The "wsock2.exe" is a self-extracting archive, you can use 7-Zip ow WinRAR to open it and …

Problem solved. I had some weird files on my account "AppData\Local\VirtualStore\Windows" folder. I deleted them and the game now selects the correct device without asking. With resolution forcing, texture filtering, 8x MSAA, 8x SGSSAA and the TnL textures issue fixed, the game is pure perfection …

Very nice work, Dege! I made a quick test, and now the affected models are rendered correctly, but the fog is totally broken. Running the game trough MS D3D with TnL forced off renders the fog fine, so it's not a game side issue. Filename 2.png File size 420.58 KiB Views 315 views File license …

Maybe something with normal normalization in software vs hardware vertex processing, the TNT2 is not a TnL hardware. They should not be different though... I might have a look into it again.

Yes, I'm aware about this, but it's not a regression in fact. I noticed it when I fixed something in the lighting calculations to be compatible with MS D3D and that's the point where it got broken. I checked it out with MS D3D and it looked the same (I also checked out old game walkthrough videos, …

Hi Dege! I found a regression that was introduced in 2.82.2 (works fine in 2.82.1 and older) that affects House of the Dead 2. The textures of the fishes that the boss of the second stage throws at you are partially white. I completed the game (only one time, so no alternative routes), and this is …
