Re: [Patch] Packard Bell Legend 300SX

I must correct myself, I've only tested with Windows 95. The GD5434 Win3.1 drivers are not working, even with today's MMIO fixes. The attached screenshot is from the Win31 Program Manager with a menu open.

[Patch] OAK Oti-037 VGA

While the Oti-037 has fewer capabilities than the already emulated Oti-067, its BIOS is somewhat pickier and did some tests that PCem didn't pass yet with the Oti-067 code, including enabling/disabling the controller, color diagnostic reading and reading from undocumented registers. The diagnostic t...

Re: [Patch] Packard Bell Legend 300SX

With the commits in the past week, PCem now emulates every system (sans some vgas and sound cards) that I've had contact prior to ~1996, this is wonderful. The PB520r is working perfectly with my HDD & BIOS dumps. EDIT: Just a quick note: most GD5434 were just 1MB with expansion slots for 2MB (the t...

Re: [Patch] Packard Bell Legend 300SX

By the way, I don't know what's different between the Cirrus 5429/5430/5434 other than bus width and other stuff that should affect only speed, but the 5429 code worked fine with the BIOS files I've extracted from two of my cards (two 5434 and one 5430 - one of them is onboard a Intel Premiere/PCI o...

Re: How music is emulated in PCem (MIDI)

I've seen it happen in real hardware, but not with the AWE32. Wrong and/or missing music and even sounds in Duke3D under Windows. Generally a reboot would fix it.

Re: v13.1 released!

Doing test releases before (for what was released as 13.0, for example) is also a good idea to warn users that there are a lot of new features and a bugfix release may be needed. Even with all the testers, some small bugs always pass (like what happened now).

[Patch] Intel Advanced/ZP

This patch adds support for the Intel Advanced/ZP (Zappa) motherboard for Socket 5. It is similar to the Advanced/EV (Endeavor) board, but has a few nice differences like the BIOS supporting CD-ROM booting (only in the First Boot Device position) and having no non-emulated on-board video/audio clutt...

286 12Mhz clock speed is slightly different

According to every datasheet I could find, the all the -12 80286s were actually 12.5MHz. This is a small difference from the round 12Mhz value currently in the code, but I thought I would report it anyway.

The screen is not redrawn when switching virtual desktops on Linux. This is worse if emulating a system without mouse, because then we can't just move the mouse to force the screen to be redrawn.

I've built this card (along with all the other cards by him.)

Re: Mach64 VT2

Rage Pro would be a very sweet card to have! Despite being known for bad driver quality, it never let me down in any game I tried between 1997-2001. Very good to hear about the (small? big?) possibility of emulating it some years in the future.

It turns out it also happens with the Endeavor, but the BIOS simply doesn't strictly check the configuration. I know that PCem mostly ignores Super IO settings in some emulated systems. In this case, a UM8669F Super IO device is emulated while both the Endeavor and Zappa use the National Semiconduct...

It's trilinear filtering, not triple buffering.

From the screenshot it seems that one of the problems with LOD is that it isn't "smooth". It seems to only change after an entire texture repetition, not mid-texture.
