Re: v13 released!

As for the OpenAL32.dll, It also performs badly here. A direct replacement is removing it and placing msys2 libopenal-1.dll in PCem's dir (not even needed to rename it).

Re: PCem 13 first impressions

omarsis81: I suggest you to try the openGL (either the normal, or the GL3) video modes instead of the older ones.
Then, use the scale filtering, output-stretch mode and maybe even the output scale options from the Video menu.

Re: Floppy does not work

I don't know if it is really a bug, but in order to make it work now, you need to go to "integrated peripherals" section of the BIOS, and there, Enable "Onboard FDD controller".

Re: NT4 could not logon after SP6a installed

I can only confirm that there seems to be some type of problem. In my case I have an original Windows NT 4 Workstation (bought in 1997 which came with Windows 95 too. I never used any of them, because they sent me an Italian version instead of Spanish). I tried installing it in PCem and works, but a...

Re: [Linux] GUI discussion

@szadycbr : There were some changes to the floppy controller. I also experienced problems running it under a windows host.
My solution consisted in going into the guest bios , there into integrated peripherals, and there enable onboard FDD controller.

Give it a try.

Re: Latest build - Cannot setup HDD/FDD/CDROM

Recently, PCem has an option to configure the IDE controller. It is required to be setup (currently it doesn't have a default setting) and you need to do so from the new wxwidgets interface (the older interface is going to be removed for v13). Alternatively, add this line to the config file: hdd_con...

Re: Windows 10 problem

Re: floppy.
Some revisions ago, I had to enter into the bios setup and enable the option "Onboard FDD controller" under integrated peripherals. Else, it would show a warning on boot up.
To me, the pcem-emulator repository sources are working with that option.

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

Mmm.. curious...

If I use the FDOS driver, with or without the cdrcache.sys, it works.

If I load the GSCDROM with the cdrcache (either with mscdex or shsucdx) it works, but if not (either with mscdex or shsucdx) it crashes.

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

When loading, they say " E-IDE/ATAPI CD-ROM device driver ver 1.25" "Copyright LG Electronics Inc 1997. All rights reserved"
Filename is GSCDROM.SYS, loaded with Microsoft's MSCDEX.

I'll try now to load it with FDOS's SHSUCDX to see if it is the loader or the driver.
