Just wanted to say that the patches you posted work wonderfully for Monkey Island EGA. No more divide error!

thanks for this. i will give this a try and see if Dave 3 and 4 recognize my PCI sound card without relying on setmul!

Glad to hear you found a workaround for the problems you were experiencing. I still can't think of a good reason why Keen Dreams would run fine while Dave 3 and 4 (with the 35 fps patch) have issues on the same system. But now that you mention Setmul, is this how you've been running Dave 3 and 4 …

That doesn't really make sense. With these patches applied, the basic frame timing in Dave 3 and 4 should be more or less the same as in Keen Dreams, and the code that updates the CRTC start and panning registers of the video card (i.e. what actually makes the scrolling happen) is exactly the same …

Alright, then you might as well try these patches for Dave 3 and 4: # Dangerous Dave 3 - Dave's Risky Rescue v1.00 (Rev 1.04): %exefile DAVE.EXE 207760 %patch $1451D $02 # set minimum frame time to 2 tics at 70 Hz (=> 35 fps) # Dangerous Dave 3 - Dave's Risky Rescue v1.01 (Rev 3): %exefile DAVE.EXE …

I also have the Dave Pack on GOG, so you don't have to send me any executables for those versions. Dave 3 and 4 should be easy 1-Byte-fixes, assuming that Keen Dreams actually does work fine on your system, anything else may take a little longer. Yep I went through Keen Dreams again and beat the …

The technology in Dave 3 and 4 is relatively close to what was used in Keen Dreams, but there are a few differences. I think the most important one is that Dave 3 and 4 will run at up to 70 fps while Keen Dreams is capped at 35 fps (as are Keen 4-6). Since you're using a relatively fast machine, …

How do you all deal with games that use CD audio? Some work when you're using Daemon and you turn on digital audio (believe that's a checkbox in Control Panel/Multimedia?), but many don't and I STILL have to use a physical disk to have CD sound (there's other hacks I've tried as well and still …

Hello and awesome work on creating a patch for the Keen games! I've always had issues running these games on my computers over the years but I've finally settled on a computer now on which I don't have this scrolling issue anymore with any of the Keen games (I'm using the Steam versions). However, …

Glad to hear it! The only situation where Setmul has given me problems is when I’m using a USB mouse in DOS using the USBMOUSE TSR.

I've tried the SoMI patch and kept getting divide errors. The solution I use for making these games work under MS-DOS is by using a utility called Setmul. You can use Setmul to disable the L1 Cache of your CPU which will slow things down enough to let you play these games properly. You can also use …

I use a Windows 98SE Pentium III for all of my retro DOS and Windows gaming. I use PowerISO to make images of my games. I use it on Windows 10 but it's also compatible with Windows 98 so if you're wanting to make the images on Win98 itself, you can do so. It just takes a little bit longer than it …
