Re: [Voodoo] Unreal

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.

Re: and... I have one more question about BIOS

Sent you a PM with a link to the PDF containing the description of the OTI-037C registers, sorry for the delay.

Re: and... I have one more question about BIOS

Sorry for taking over the topic, win3200, I hope that you get your PC working. The award 286 clone seems to be the right starting point to implement your machine in PCem. @Battler: Sure, I will PM you with both the video and system bios. Although I think that they are fairly generic. Also, in PCem v...

Re: and... I have one more question about BIOS

I was able to emulate another korean PC (Hyundai Super 286-TR) that uses the same 82C235/82C710 chipset just by dumping the bios and loading it on PCem. Works fine except for the occasional "Memory refresh error" on boot, which is skippable.

Re: Recommended configurations?

Just a quick note: when running at 100% with an emulated Pentium, anything less than Infinite cache makes peformance worse than in the real computers I own.

Re: Award286 clone

I dumped the BIOS from an old 286 of mine (Hyundai Super 286-TR) which used this chipset and it actually worked! Only problem is that sometimes "refresh timing error" is displayed after POST, but it is 100% stable after lots of testing. Thanks!

Re: v10 released!

I'm guessing that BIOS label only shows that a PS/2 mouse was detected, not a serial one (I doubt the BIOS tries to detect serial mice, because the ports are not dedicated)

Re: v10 released!

I'm am using Advanced/EV without any major problems, it is very similar to the Advanced/ZP board I've had in the mid-90's. Most of these intel boards didn't even have the PS/2 extension bracket installed anyway, I've never seen one until those cheap AT K6-2 boards appeared. Slight bug with MACH64/Pe...

Re: Security issues in PCem [possible emulator escape]

qemu, VMWARE, VirtualBox all have had security advisories.


Off-topic: ZSNES was great for its time and constrained resources, higan is best for modern machines simply because of accuracy (even after all the NIH syndrome problems)

Re: original resolution output?

There's also the problem of actually achieving resolutions like 320x200 on a modern operating system. Windows, its drivers and modern video card may get in the way, even if all is OK with the monitor. The way to do this is doubling pixels and having black bars when the native resolution isn't a mult...
