Re: PCem 13.1 HDD problem

Not sure if it's related at all, but I've noticed that the BIOSes of all machines behave exactly this way (completely failing to see that any HDD is installed at all) if the HDD image file is read-only. I ran into that once and was tearing my hair out for a while until I figured it out. PCem should ...

Execution rate at DOS prompt, menus, etc.

Finally getting a chance to play around with PCem 13.1, and sure enough, it looks like some of those recent dynarec tweaks have MASSIVELY improved execution rates at the DOS prompt, game menus, and other idle-loop areas that previously brought the emulator to its knees. These loops do still cause no...

Excellent work, EluanCM! This is great to see, and something I've been looking forward to ever since you first brought up your interest in it many months ago. Thanks for sticking with it. Hopefully Sarah will commit this patch after she returns from her much-deserved break... :)

Re: Destruction Derby for DOS slows down a lot under Windows 9x

Does this same commit improve the issue of the recompiler choking at the Windows desktop, DOS prompt, etc.? Can't compile the latest version to check at the moment, but I'm curious. If so, that's a huge step forward!

Re: FPU on emulation of pre-486 machines...

Count me as yet another who would love to see this! I really do hope that at least some level of basic 8087/287/387 support gets onto the to-do list for v14. Also, does anyone know if the FWAIT issue Scali mentioned above has ever been fixed?

Re: [Patch] Epson PC AX3

Are you saying that the number entered is being treated as MB despite being labeled KB? For example, in your screenshot, would PCem improperly attempt to give the system 512 MB of RAM instead of the expected 512 KB? Or are you just saying you find it strange that the AMI 386SX asks for a RAM amount ...

Be careful! 386 SX models count memory as KB in the configuration dialog where it should be in MB

Re: [BUG] System shock crash on launch on specific cases

Even if it's just caused by a poorly patched ISO, isn't it still a bad sign that PCem itself is crashing/fataling? The failure should be contained within the emulated system, so there's still something amiss to troubleshoot here, right?

Re: Patches for wxWidgets/SDL2

I'd think that the UI should certainly make it very obvious to the user which settings will be applied globally and which will be applied per-machine. Lots of potential for confusion there.

Re: Development screenshots

The render thread count is per-card, so you can have 4 render threads in total (plus 2 FIFO threads). So you will need at least a Core i7 to run it flat out. If you just want the resolution though, setting 1 render thread per card is often fast enough on quad core systems. I'm a bit confused by the...

Re: Olivetti GO481 video card

If the Olivetti GO481 only came in a 256K version, then it's not unreasonable to expect the user to know that or look it up. The fact that the PVGA1A itself supported 512K and 1M boards doesn't really seem relevant here. In any case, if we were to decide that it's worth making the memory size explic...

The amount of memory is surely 256K B , not 256K b (32KB), right? I know it's a minor detail, but I can see some potential for user confusion here, so it should probably be corrected. And for that matter, isn't it a bit inconsistent to be listing the memory amount right in the displayed name of the ...

Something I've always wondered about: why is the video speed user-selectable? Won't there always be a single most sensible value for that setting for any given board choice and machine configuration?

Apologies if I'm missing something obvious here, but why is the IBM ESDI Fixed Disk Controller marked "is_mfm" for PCem's purposes, while the Western Digital WD1007V-SE1 ESDI controller is not? Is this related to what was mentioned a bit upthread about the IBM controller being limited to two drives?
