Re: FredPJ's feature suggestions

Startmenu, that game in your screenshot looks hauntingly familiar but I can't quite place it. What is it?

(Also, I agree that a 4:3 windowed mode, preferably with window resizing enabled, would be a fantastic addition to PCem.)

PATCH: Correction in loading of Endeavor BIOS

Attached is a patch for mem.c which corrects a minor error in the loading of the Endeavor's BIOS. The current code seems to presume that the Endeavor uses the same size BIOS as the Batman's Revenge, which is wrong. Of course, in actual hardware terms they both use similar 128 KB Flash ROMs, but in f...

Re: Dynarec execution rate plummeting drastically at DOS pro

Good to know. I had been confusing the HMA with one of the memory areas just below the 1 MB boundary. Realizing now that it's just above that boundary, what you say makes sense, and probably does explain what's going on here. It's not a big deal, but it would be nice to get that code sorted that's s...

Re: Dynarec execution rate plummeting drastically at DOS pro

For me it's definitely not related to the cache setting. There's something else going on. Are you using EMM386 or similar? If so, try disabling it. I've found that EMM386 triggers another entirely unrelated bug in PCem that drastically slows down the emulated PC under certain conditions, thereby art...

Re: Dynarec execution rate plummeting drastically at DOS pro

Sorry to bump this, but I've now noticed something else of interest in relation to this. Regardless of how the emulated system is configured, when DOS is loaded "low"/"noumb", the dynarec doesn't choke at the DOS prompt at all. The execution rate never dips below 100% at all, even when emulating the...

Re: v10 released!

It's been years since I actually played with one of these boards, but I could have sworn that that particular BIOS managed to detect the presence of serial mice as well. I might be thinking of a different board, though.

D'oh! There are actually two issues, one of which was entirely my fault, and I appear to have conflat...

Re: v10 released!

Sorry, should have been more clear--the Advanced/EV is currently unusable, because the BIOS detects no mouse at all. Battler seems to think that fixing this will be as simple as switching the mouse init on that machine over to PS/2. Been so swamped I haven't had a chance to verify that, and alas sti...

Re: Dynarec execution rate plummeting drastically at DOS pro

That was a clean boot of DOS 6.22, on a Winchip 240 (the fastest CPU emulated when I started the recompiler, somewhat slower than the Pentium MMXes you can emulate now), on a 3.6 GHz Ivy Bridge Core i5. If your setup differs from this at all then I'd expect the performance to drop somewhat. Thanks ...

Dynarec execution rate plummeting drastically at DOS prompt

In general, I've been getting great performance out of the dynarec, but I've noticed that the execution percentage plummets strangely while idling at the DOS prompt, in ways that suggest that something other than the usual issue of an idle loop hitting one of the dynarec's weak points may be the cul...

Patch: Fix for error in re-ordering of ROM set enum

An oversight in the re-ordering of the ROM set enum in r346 has caused problems for the Phoenix 386 and the DTK 386, which have now lost their 386 classification. Actually, the problem was worse than that, as there were several misclassifications even before the re-ordering in r346 (IBM PS/1 Model 2...
