Re: Tips for newbies

I will be happy for some tips: 1. Which IDE are you using for windows? I'm using Dev-C++, but that's because I'm used to it rather than it being any good. 2. Is there any documentation for the code structure and main classes / functions? Not really, I'm not very good at documentation! It mainly dep...

Re: What computer processor to emulate pentium mmx and up with PCem well?

why not use one thread as a CPU and slow this thread accordingly without need of emulating that CPU? Because that would be a completely different project. Also how would you propose to slow the thread with a sufficient level of control to emulate the performance characteristics of the desired emula...

Re: Where Is The Donation Section For PCem Project ?

Correct. Quoting myself from another thread : I've tried accepting donations in the past on another project (RPCemu). My experience was that it just put pressure on me to force myself to work on the project when I was burnt out, or otherwise not in a state to work on it. That's something I really do...

Re: CGA / Hercules refresh rates

Hercules could either be that the emulated 6845 clock is a bit off, or that there's some bug in the 6845 emulation resulting in horizontal or vertical timings being too short. Or that the PIT is running slightly slow, maybe an one-by-one bug somewhere. Hercules software generally isn't timing critic...

Re: 768kB RAM on Generic Turbo XT

The extra 128kB should be accessible as conventional/base memory if you're using MDA/CGA/Hercules video. EGA/VGA and later will render it inaccessible.

Re: v15 compatibility & bug list (WIP)

You can see how much CPU time the Voodoo threads are taking in the PCem status window. The percentage before the frames/sec line is the FIFO thread (though I think this is a grotesque overestimate, and counts the time this thread waits on the render threads), the two percentages below frames/sec are...

Re: v15 released!

Not a lot for the most part; the main CPU load is the CPU emulation, and that's strictly single threaded. The only reason to go past 4 cores is if you want to emulate a Voodoo 2 SLI setup, as the Voodoo emulation can use up to 3 threads per card.

One of the problems with implementing timing for the K5 is that AMD never publicly documented what actually changed between the SSA/5 and 5K86 - and clearly there were some major changes, given how different the per-clock performance on the two cores is! At some point I need to sit down with both ch...
