Re: How do you get GUS working in pcem?

I didn't get it working, I just read that post to help you. If the problem is the memory, move something to the upper memory. Load HIMEM.SYS on the config.sys file and then add the line DOS=HIGH in the same config.sys If you can't get it to work, google "load DOS into high memory", also, there was a...

Re: Hardware SID boards emulation

Nice to see a good programmer around here!
I hope your code your code could be put to a good use!

If you know x86 architecture, I think PCem needs some optimization there, maybe you can help there too!

Re: [PATCH] CGA improvements

After watching this video https://www.youtube.com/watch?v=niKblgZupOc I decided to try CGA Composite mode, but I found it look very different from what we can see in the vid.
Did this patch fix this? I tested PCem 11 official release without any patches

Re: Tandy 1000 Fun!

Welcome to the forum!
And while still not perfect, I also believe this is the best emulator out there.

Since we have some 1000 models already emulated, I think it shouldn't be difficult in emulatin additional models.
Do you know that chipset drives the 286 in the TL/3?

Agreed, I'm running Windows 8.1 64 and and EGA works fine, Windows 10 should work too.

Re: [Feature request] LIM EMS support

As Blatter said, what you are looking for I believe is on the Award 286.
I can enter the BIOS screen, but I couldn't boot an OS with the floppy drives

Is this what you are looking for? Or you still need that card?

Re: [Feature request] LIM EMS support

I guess using XMS memory with HIMEM.SYS won´t do, right?

Just out of curiosity, what application or game for a XT or 286 uses more than the 640KB conventional memory? So far I know none

Re: Things that need to be twaked/improved: cache

The cache emulation is complete garbage, and I would have removed it if I hadn't had numerous people asking me not to. It isn't possible to do even remotely accurate cache emulation without destroying emulator performance. I believe the goal of every emulator is to be a close to the real thing as p...

Re: Things that need to be twaked/improved: cache

In my opinion, L1 should be hardcoded and shouldn't be allowed to be altered, 16+16 kb on the Pentium MMX. You can, however, provide different options for L2 motherboard cache, 128, 256, 512, 1 or 2MB.

Thank you, and sorry for the long post

Things that need to be twaked/improved: cache

I run SpeedSys in a real 430VX motherboard with a Pentium MMX 233 and then compared with PCem11. Big surprise! L1 is way out of scale compared to real microprocessor. Pentiums MMX have 16 kb L1 for data (what is measured by SpeedSys). PCem, reports 64 kb using "a little" cache; 128 kb using "a bit" ...

Probably a dumb question, but here it goes: could we get significant performance benefit IF PCem would be written in assembler? I know it´s almost impossible because of its difficulty, but I ask anyway
