90210 is our first demo for PC and it was finished at spring 1995. So it is bugged, and these bugs will be NOT fixed, because we are unable to compile these old sources. But it is still possible to run it, if you have some luck and skill.
Firstly, which operating system is needed: You need MS-DOS (5.0+ ?), or Win95/98. And QEMM or some other memory manager, which will give you 626.080 BYTES of free base (640k) memory. (If you have Gravis Ultrasound, you need 10.000 B LESS of free memory, at least we hope ;) )
This will be probably the biggest problem, because 614kB of free base memory is nearly impossible to get. If you will get over this point, than it is very likely, that you will run 90210 successfully. 90210 should work under W95 well, but we suggest you to boot pure MS-DOS.Now, check, if you have at least about 1.5MB of free EMS memory. If not, than the trouble with memory continues. (QEMM is commercial software, what's pity, because with QEMM it's just a piece of cake)
Now, check, if your environment variable for your soundcard is correctly set (ULTRASND or BLASTER, depends on type of card).
We are getting to the execution:
write "90210" and hit enter. The demo should do one of these 4 things:
If the demo does something else, than these 4 described things, than you have
either failed to follow the instructions correctly, or you have too much exotic
configuration to run this demo.
BTW, if there is someone, who is able to capture the demo in AVI file, we will be thankful for that (or even for some screenshots). Because we were unable to do it. And it will become harder and harder to run this demo with the time, so we want to have it in some viewable form.
