486 DX2/DX4 now misreport speeds in SiS496

Both AMD and Intel 486 DX2/4 processors misreport their MHz on bootup. iDX4/100 is now 50mhz, etc. Didn't try Cyrix.

Don't know which commit did this. AMI486 seems fine from what I can tell.

Re: 3DFX emulation

As much as i'd hate to bump old threads, i've recently failed an attempt to up the taps of the bilinear filter to 128 hoping for just enough precision to be appropriate for the color depth and the lightmap blending (which is currently reminiscent of the 4-bit precision of a PowerVR PCX2's alpha text...

Re: [REQUEST] CD-ROM speed

The appropriate whirring noises would also have to be emulated. Don't know if there can be an organized effort to sample the hardware we have for sound, like getting a drive to record a cd/diskette being copied and going through the insert/eject cycle etc.

Re: [REQUEST] CD-ROM speed

A slower CD-ROM speed would probably benefit......certain games' installers that give out game lore by sound as the installer goes. Activision titles come to mind (Interstate '76, Battlezone, etc) some selectable speeds like 1x, 2x, 4x, 8x, 16x and MAX It doesn't have to stop at 16x. We could go all...

Win3.x splash image appears too fast?

I recall around 93-94 this would smoothly draw from top down as the OS loads and would take a few seconds on a slow 486SX-33, in PCem it appears instantly even on 386SX VGA systems.

Re: Paradise Bahamasw 64 (S3 Vision864)

Re: v14 feature freeze end of Saturday 17th of March

I don't think it does. You're probably creating an image over some fragments. For me, it didn't take 2 minutes to make a 40gb today. what takes longer though is moving all those smaller images into the bigger ones since there's no real easy img-based tools to do so and WinImage drag-and-drop isn't r...

Re: [Patch] Packard Bell Legend 300SX

It could also help if you tried different software to dump your image to see if that's a factor. I've had some better results on 91-95 software dumped through CloneDVD (with .cue creation enabled as well).

Re: v14 feature freeze end of Saturday 17th of March

A higher cylinder limit could help. There are times I wish I had a bit more space so I wouldn't have to make 15 8gb images to test across many configurations. Most of the games dumped in them are from hard drive migrations and often have redundancy

MegaPC Tseng slowness

Noticed the last commit and wanted to try that out immediately. When ET4000AX is used in a MegaPC it'll be slow in many games (i.e. Major Stryker). Doesn't affect AMI386 in the same way. Built-in video (VGA) is fine. Real behavior? DISCLAIMER: I'm only using the MegaPC for the working Phoenix 386SX ...

If there is one it should be owned by Sarah. I'm not a fan of fan-owned emulation discords for the general grief they bring and would liekly serve as a huge distraction towards time spent working on the emulator.

Re: I know it's technically too late to add new machines

Having Pentium II emulation would mean a recompiler rewrite first as the P6 architecture is wildly different on how it treats instructions and cache. You can't just take Pentium and clock it up and change a few CPUIDs around to emulate a Pentium II.

Re: SB16 MIDI in Windows ME

WinME always ate the autoexec.bat in a desperate attempt to remove all real-mode drivers and enforce WDM. This also affects SB16 emulation TSRs on the SB Live for example
