I have successfully applied the patch to SVN and the binary runs normally. However, I am having trouble getting a Voodoo card to detect. What parameters should I be using to enable the card in the configuration file? I was previously using these settings with kekko's 3dfx patch: [pci] # voodoo: …

Is there any chance of this being converted to an SVN-compatible patch in the future, or are there too many Libretro-specific dependencies? I did create a diff and check out the code changes, but could not make much sense of it.

I have spent some time applying some further tweaks of my own to "crt-lottes-tweaked" which, in my opinion, duplicate the look and feel of "crt-lottes-fast.subtle+gain". I did this because, as much as I like the latter shader, I was never satisfied with the lack of easy configurability in relation …

Does anyone know how to increase the saturation in the "CRT-lottes" and "CRT-lottes.tweaked" shaders? My favorite for 90s VGA / Windows era is still "crt-lottes-fast.subtle+gain" but for CGA/EGA I think the original lottes shaders have an edge. The only problem is that the colors do appear more …

Are you really sure that A-10 Tank Killer II runs on Windows 3.x? I thought it was one early DirectX game... I don’t have the box anymore, but my manual is dated 1996 and contains instructions for installing in both Windows 95 and 3.1. Unfortunately, there are no trouble shooting tips, and the …

Thank you. That certainly gives me a few leads to investigate. I’ll try locating the older version of Alcohol first, then DOSBox-X. I knew it supported the virtualized optical drive, but I’m unsure how/if it handles mixed mode CDs with CD audio tracks.

The other thing I have realized is that in Skate or Die, the intro music needs the "sampleaccurate" feature enabled, but the in-game events use standard PC speaker music. So if you use that feature you will get distorted music in the main game. Seems you cannot have accurate music for both at the …

You can get Skate or Die to play its samples properly in a fork of DOSBox which has the sampleaccurate patch applied. If the patch is complied into the fork, it works well when set to "true" with samples which play back on the Tandy or Adlib sound chips. It will corrupt PC Speaker sample playback, …

Generally, I find that the Tandy sound emulation in DOSBox is very good, although I have to admit that it has been many many years since I heard the output from a real Tandy PC. However, in Skate or Die, something has always sounded off, and so I got around to testing the game in PCem (v17) as a …

After all that, I only just realized that control-esc does work in Windows 95 and 98, so I can still use that to access the task bar in most instances (and hence swap the images using the Virtual Clone Drive menu bar icon). Not as quick or user-friendly as a key combination, but it gets the job …
