It wasn't until 286 and 386s that that kind of side-scroller game started to be common, I think.

4.77 just isn't a lot of horsepower, especially if you want color.

      Honestly, I was expecting it to become a slide show seeing that it "should" go down to 4.77MHz if it's off IIRC. Maybe it dropped from 50MHz to 25MHz instead? (Just cut the CPU speed in half?)

          I was just thinking 4.77MHz because a lot of the games on the IBM PC/XT time weren't controlled by anything besides CPU speed so they ran at light speed once MHz started to increase. I thought turning turbo off tried to re-emulate that speed to make those programs work correctly again. I might just ... more
          • There was also a utility called mo_so or slow down or someth - Puckdropper, Wed Jan 12 2022 3:28pm
            Thing similar. I had to use it for a game that was running to fast, but I can't remember what it was. So some systems just slowed the CPU down by disabling caches or skipping cycles. Others really did try to hit 4.77 mHz. I wonder if Delivery Rush can be played on an XT if the graphics were simp... more
