Hmm, I guess I got confused by the forum title which says "Getting old DOS games working". Sorry. Anyway, I spoke too soon. It still crashes. When I run it in Windows, instead of the computer getting locked up I get a "This program performed an illegal operation" message and it gets shut down. But, …

I think all of this stuff is slowly starting to make sense! I've been tinkering with the EMM386 RAM I=[values] and discovered that on my system, B000-B7FF are safe. C000 and D000 are not, and when I attempt to use them, the game won't run, or show graphical glitches. Although the upper memory …

Setting EMM386 to RAM makes EMS possible. TO access the EMS Memory (your memory above 1MB) a 64KB Block in the upper Memory is USED! These 64KB are not available for uploading drivers anymore! But I do not use NOEMS Option in every of my systems, it is simply USELESS. Games that need EMS will not …

You need more UMBs and fewer loaded drivers. EMS consumes a 64K page frame in upper memory, which wipes out an entire segment into which you would otherwise load modules, and there aren't that many segments to go around. You don't need SETVER or DISPLAY. If Arena doesn't run from a CD then you …

Try MSD and look for fragmented upper-memory. OK, started MSD and selected the memory. It gives me an overview of the memory blocks in 640K to 1024K, and I guess I kinda see what it's all supposed to mean. This is what I can gather, based on the legend (EMM386 set to RAM): F000 - FFFF = ROM E400 - …

If memmaker does not work for you there must be something with the machine. What machine is that and what cards (ISA/PCI/AGP) are already in it. It's a (relatively modern) Gateway Solo 5300, PIII 600 mhz, with 192MB's of ram (although I've removed 128MB just to see if it's not the amount of memory …

I think your main problem is that your system has too many (or too big) ROM modules or other hardware that take up most of the low-end 1 megabyte address space. In other words, there aren't really any free upper memory blocks (UMBs) that you could use to load stuff into high memory. Please check …

... Do you have a dos=high,umb at the beginning of your config.sys ? If not, add it and reboot . I saw a separate dos=umb and later on dos=high in there. Probably not at the beginning, I guess! Will check tomorrow, spent way too much time on this tonight (again), and if I wake up either her or our …

Hey everyone, I've been lurking around on this site since forever, because more than once I've been able to find a solution or workaround for a retrogaming problem I have been facing every now and then. Decided to create an account now, because I'm having a problem that I just can't wrap my head …
