I've read in Emulatronia about a new PC Emulator, PCEm. It currently emulates PC and XT computers. It seems it is in early stages, so some devices are not emulated (some PCs fail to pass test). Have anyone tested it?

I am going to test it just for the sake of it. Too bad it doesn't emulate EGA/VGA (yet).

Thanks for the link.

I tried it and after the interface started and the emulation started (got into the BASIC thing) I couldn't do much else. It got my computer stuck 3 or 4 times.

AMD Athlon XP 2400+ 2.0GHz
1.50MB RAM
Windows XP Professional

Had to hard reset my computer each time in order to regain control of the machine.
Doesn't look bad though but I guess it's resources hungry.
Waiting for further tests

Same here. I started as AMSTRAD PC1512, did the POST sequence, and after the message "Insert a SYSTEM disk" showed, the emulator got stuck as soon as I press an option from the menu.

I _think_ I've tracked down these problems. I've updated the copy on the PCem site, can someone give it a try?

Now it doesn't freeze anymore. I tried only a game on the fly to test it after the author updated the emulator and it seems to run quite fast (playable).

According to the author, the bug only affected non-dual-core machines.

Bubble Bobble, one of the hardest games to make work in Windows XP (Only DOSBox had made it so far), not only works, but the game also recognizes an inferior processor and/or a lesser amount of RAM, making you face a few less enemies on some levels, which happens if you play it on an actual 8086/8088.
Needless to say that it's playable, although some almost imperceptible delay occurs between keystroke and reaction of the character but currently I'm testing it on my notebook which, obviously, doesn't have the same performance as my desktop PC.

Scopa, an Italian card game, on the other hand, doesn't work. It's an extremely "simple" version of the game since it works on CRT, without a graphics adapter. When I have to select the necessary points to win a game (usually 21, 11 or 37) it doesn't hang but it looks like it won't accept any value. http://anonym.to/http://en.wikipedia.org/wiki/Scopa

CPM/86 operating system seems to work. I couldn't do much testing because I didn't learn how to use it yet. Anyway as you can see it succeeded in booting!

I'm bumping this old thread because there was a release in July of this year and this emulator is interesting just for emulating the AMI BIOS alone! I think it needs more attention because although the 486 emulation is very broken, it's noneoftheless very promising.

How the July release missed anyone's radar here I don't really know.

So how does this compare to Bochs?

Also, is there an updated link to the author's site, now that Geocities is kaput?

After my post there was a 0.41a release

BTW can anyone verify the accuracy of the speed of the 486SX 40MHz emulation? I had a crappy ISA video card back then so I don't really know, I don't remember Doom running that fast on 40mhz.

Run 3dbench (1.0) which you can find attached at the start of the 3dbench database thread!

I get 21.2 with 486 40MHz, which matches 5u3's 486 40MHz result. So YES!

Excellent!

PS: I knew that database would come in handy one day Laughing Out Loud

That's the kind of thing I was hoping people would use this database for...

Hi TomWalker, Can one use any Bios or does the emu check the crc?

I've been wondering where I'll find the bios for each system.
Googling didn't help for 386/486 Sticking Tongue Out.
Is it illegal to distribute one?
