Doom8088 with the whole WAD file in XMS memory

This video shows Doom8088 on a 386SX @ 20MHz with the whole WAD file in extended memory. Once the WAD file is loaded into memory, the hard disk is not accessed anymore. This is good for performance.

The performance is really good! Also interesting idea caching all the WAD on memory, maybe I can do something similar in FastDoom.

Incredible! Incredible work! Nice job.

If you set up an old device, the IDE compatible CF card turns on its coprocessor to speed up the system. Doom demo screen, the intro turns it on after 20-30 watches, the computer will be faster if the cf card is in. Does not work with microdrive, it does not have a coprocessor. Old 256 mb card is good for the extra speed. Causes very fast file execution, copying.

I've tried using a CF card in this 386 computer, but it gave an error during POST. Then I thought "Why not use a RAM drive?" and then I thought "Why not build-in RAM drive support into the game" and that's how the XMS feature got started.

You should get in touch with Randy Linden, He made quake run on the GBA and Doom on the SNES. (He might be willing to help you)

[@DookNookim]

That's an interesting idea.

@@DookNookim Another suggestion is to add Mipmapping (If you haven’t already, I cant really tell due to the low resolution)

[@DookNookim]

@@MasterMadLad There is a little bit of mipmapping github.com/doomhack/GBADoom/issues/51#issuecomment-2198123732

THat's awesome

I wonder if this would run on a Compaq Portable II.

[@DookNookim]

Doom8088 needs a VGA or MCGA card and a Compaq Portable II has a CGA card, right? So that won't work. However, doomtd3 will run if there's enough memory in the Compaq Portable II. Doom8088 CGA support is on the To-Do list.

if he played like that on i286, then good. and on 386, regular Doom runs just the same, and with better graphics, and not so sloppy.

[@8-bitcentral31]

Not on a 386sx20. Such a CPU runs standard doom around 1-2 fps, completely unplable. You can run fast doom on a 386 like this but it looks about the same if not worse (does have soundcard support though). This: kzbin.info/www/bejne/gXbLeqqCj5VpmsU shows the performance of this port at lowest settings on an emulated 286, its amazing that it cann run at all on such a CPU.

[@DookNookim]

This 386 is the slowest computer I have that has a VGA card. I am experimenting with CGA graphics...

@@DookNookim Really! That would be awsome, its brilliant seeing how this project is continuing.

shareware WAD or full? That does make quite a difference.
