Re: PCem v18 News (Was v17 Notice)

I guess tk421 choose a poor example of a game from that era to make his point. There are other games from that era that require a machine faster than PCem, and are not compatible with contemporary Windows, and are worth playing. Fans of those games would look to alternatives, a physical retro PC fr...

Re: PCem v18 News (Was v17 Notice)

I really hope the 13th gen Intel laptop CPUs can do the job. Unreal Tournament (1999) is always fun to play, but it would be nice to get it running at 100% in PCem. VMWare runs the game fine, but PCem is so cool. Just curious why would one want to use PCem for this game, aside cool ? It does run na...

Re: How to Detect PCem Programmatically?

Why not invert the question? Try to detect the others by intrinsic or otherwise unique devices/features, and if it's none of them it has to be PCem.

Not sure if PCem is what you should aim for, since you seem to mix up parallel (LPT) and serial (COM). I have used physical COM ports with vanilla DosBox to quite a degree of success, regardless if the host bus was ISA, PCI, PCIe or USB. https://www.dosbox.com/wiki/Configuration:SerialPort If you th...

Understood.

Sound Blaster PCI128

There's still that Direct3D 6-7 primary device gap that VM software can't touch. Also as for VirtualBox, they're retiring the video device that brings 2K/XP OpenGL passthrough pretty soon.

Indeed. You'll never solve this problem within Win9x, no matter how you turn it.

Those will likely never get a connection nowadays due to lack of TLSv1.2 support. TLSv.1.0, SSLv3.0 and older are outdated and usually no longer available. Most providers have also removed abilities for unencrypted connections alltogether. You can try to change your POP3/IMAP/SMTP settings to SSL/TL...

Re: Possiblity of implementing cache emulation

I think perfect cache emulation is something we all like to have with PCem Why? There is no speed gain from it. On a physical computer speed gain with cache arises from the fact that cache memory is several orders of magnitute faster than DRAM. In PCem all emulation is taking place in it's host DRA...
