PCem

Replacing the udvd driver with oakcdrom.sys (yes it's non-Free) on the floppy media seemed to let FreeDOS 1.2 install. Haven't dug around for any Free CD drivers that do work yet. FreeDOS 1.2 seems to hang on 8088s too which defeats the idea of FreeDOS with a Free BIOS (Xi8088) with XTIDE on CGA :( ...

I'm not feeling up to giving out EXEs anyway. It'd have some of my hacky stuff applied to it and be nowhere as optimized, and I have a feeling if I do, i'll have to make a huge zip with all the dependencies...

I'm using the version of PCEM datestamped 12/19/2017.

Upgrade. V14 recently came out and you'll likely have more support for that than a 6 month old build.

I'm still working a bit on this but decided to put it out early as I really need a break from this (4 trial and errory days so far). I'd prefer technical feedback on this. It's not ready for the tree in its current state (still have comments and the tabs/spacing isn't consistent as I code in a notep...

Oddly I get this bug with the release build from the site, but not in a self-made wx 3.0 gcc 4.7.2 build from the current revision. :S

Here's a naive attempt at recreating the double-sized dither, which apparently only should apply to the 4x4 dithered triangles when they are blending (2x2 dithering, mostly seen under 3dfx's Direct3D HAL, and UnrealEngine should not be affected by this patch at all). It's a slow implementation for t...

Still on a Midway sports kick NBA Jam Tournament Edition (DOS) has flickering issues no matter the speed and it occurs on Trio64 and Cirrus GD543x NBA Hangtime (Windows) runs perfectly. Same PMMX233 system above on AWE32/W95. Also Cyberbykes can have the same Magic Carpet VGA issue with Trio64 if yo...

A Phenom II 3GHz probably can only handle a P90 at best at this time (v14). I don't know whether the future recompiler rewrite will benefit it or not.

Still not a 100% method but good enough. (And the rips with different hashes had no audible differences anyway) Trial and error's always a huge part of the CD ripping process. Sometimes you'll desire some of these error corrections.... I've a particular older game (1993 Win3.1 CD game) that refused...

It is a very bad idea to preserve games with lossy audio tracks Tell that to GOG. About all of their CD image games are an obfuscated bin/cue with compressed audio tracks (and sadly some of them wipe the data track clean) I did once try to make myself ogg images (for similar massive space saving re...

It's totally possible to have it work within pure DOS with the Creative drivers. Some drivers/installers don't modify the autoexec.bat appropriately, but it's doable. Just call \progra~1\creative\audio\dosdrv\sbinit.com.

Doing the Soundscape emulation part however I still haven't figured out...

What motherboard are you using? If 430vx, have you tried to reset pci configuration within the BIOS and let Windows refind all the hardware?

I can Virge + SBPCI128 + V2SLI just fine.

It's already there.

Voodoo2 8mb = 4mb framebuffer, 2mb texture memory * 2 texture mapping units
Voodoo2 12mb = 4mb framebuffer, 4mb texture memory * 2 texture mapping units

(In case you're wondering, Voodoo2s with a 2mb framebuffer live in some arcade machines.)

More joysticks in general would be interesting, though only a few resemble the common DS3/X360 pad. Closest I can think that does in the emulated period is the SV262 and that's not a sidewinder so it's O/T .

Reddit's been positive.

Check your rom casing.

Not being able to use pentium roms means I can't use voodoo, which I really want.

Not entirely true... you CAN use a Voodoo/Voodoo2 with a 486 on SiS496

Probably a Core i5 that's not too old at least. Aim for 4ghz Serious Sam however on a real PMMX machine it will be slow . That game really demands more of a Pentium III 700Mhz at least to be playable to the end (or more at a minimum, a P2 400), all targets that aren't feasible to emulate with curren...

NFL Blitz 2000 also gives a CMDFIFO crash to Voodoo2 when using the Glide3x backend Bad CMDFIFO packet 3f49cb0e 0011f1b0 Bad CMDFIFO packet 433ad032 0011f1b4 and when using Glide2x, there's this fog bug: blitz2kf.jpg It'll also cause a bad LFB crash sometimes Swap buffer 00000000 1 0FA105B0 0 Swap b...

Don't delete then recreate your exact post to bump the topic to the top.

You can't do 800x600 with Z on a 2mb framebuffer. Up that to 4mb.

Escape to the main menu and click here
Also unrelated, the latest commit also fixes Rainbow Six's missing loading screen bug

It's not a PCem bug.

You'll have to configure Tomb Raider 2 to point to the Voodoo2 and not Primary Display Driver (in which it'll drop to software rendering otherwise), tick all the checkboxes, and then it'll look fine

On the double-sized blending dither argument I've noticed MAME's voodoo code does emulate it, at least for War Final Assault. Little clip of a flamethrower producing the overdraw necessary, sized up 300% bigdither.png MAME doesn't have the radial LOD bias or the screen filter though (and probably no...

Is DOSbox in machine=vgaonly?

I'm hearing crackles on CPU speeds that low (p75) on just a Sound Blaster 16 with F22 Lightning II (same sound system) so it could probably rule out the SBPCI. I just happened to try it on a fresh packard config testing run

The Earthworm Jim sound fix also fixes sound in the unreleased Super Star Wars DOS port

430VX PMMX233 Win95C AWE32. I believe i'm using S3 Trio64 drivers provided by DirectX 6. I'm running this from Win95 (as I did then because I didn't use real-mode CD-ROM TSRs all that much to play from within DOS)

Desktop res is 800x600x16 and it's a 1MB Trio64 card

Run the SB16 installation disks from dos starting from the first floppy and point it to your Windows folder when it asks. Then the next time you start Windows 3.1 it should immediately set up the card and add program groups.
