Re: Would like to add my own ROMs to PCem for personal use.
sorry for hijacking this thread .. I found a lot of ROMs for vintage computers .. is it possible to add them by my own or are the emulated machines hard wired in PCem?

Re: Schneider Euro PC

Re: Schneider Euro PC
btw. in terms of accuracy .. comparing topbench results with pcem (v13) shows that the emulated machines are about 25% faster than the benched real machines, mainly because of faster memory access, cpu speed seems to be nearly exact ..

Schneider Euro PC
Hi folks,
I can't save BIOS settings, the machine always starts with "cleared" BIOS settings, especially with 640 kb memory, no disc drive and at 4.77 MHz clock speed.
Do you have any suggestions? I didn't discover that with other machines. Where does PCem (linux) save the BIOS settings?

Re: Using special machine types
I see the point, but in most cases standard software won't see any difference?! .. how will the special machine types perform compared to the real machines? Can I expect that for example the Commodore PC30-III emulation will (nearly) have the same performance like the original machine?

Using special machine types
There are a lot of special machines emulated. But what is the advantage/disadvantage of using for example an AMI 286 clone vs. Epson PC AX or Dell System 200 ? Are the special systems more accurate emulated ? And if it matters, which one of the 286s models would you recommend ?

[BUG?] VGA - color brightness
Hi,
seems, that DOSBox and PCem (linux) render the colors differently .. colors look too bright in PCem for the 18bit RGB values ?! It doesn't matter, if software or openGL rendering ..
