This is not so suprising since P3 was used as the baseline for Core 2 technology and P4 was dumped entirely.

Yeah Windows XP does require Pentium, because it checks the processor type and refuses to run with anything lower, it won't however use pentium specific instructions. So it would work with 100MHz 486 if it wasn't built in a way that it doesn't allow the use of 486 processor. Windows 2000 does work …

Wrong GM port?

I looked at your link and someone already was complaining that the card doesn't work with XP SP3 😒

I can't even find 486 parts any more, Pentiums are rare too 🙁 I have 100Mhz Pentium I for retro gaming, altough I run most of the games emulated with my Core 2 machine.

I have a nice Yamaha made MIDI board with 26pin connector on my SB16 ISA. Is there any way to use it in modern computers and operating systems (well not too modern, Windows XP).

Is there a list of games that are improved significantly with the new version?

I think it could be an issue with the gameport? If it's not in a soundcard but integrated to the motherboard. I never got it to work properly in XP but 98 it does.

Thx!

I completed the game with 40Mhz 386, not sure about how much cache.

What joystick is it?

I think X-COM music was originally written for Roland cards and General MIDI support came with a later patch.

I have a high end Core 2 duo machine but still X-COM runs slow, except when in the map part it runs allright. What can I do to try to make it faster? I think Master of Orion II has the same system requirements and it runs better than X-COM. This is the original X-COM Apocalypse from 1997 by the way, …

I tought for a moment it hanged on me too, but it worked after 5 or so minutes. The problem was in the part where it checked cdrom speed.
