I really wish I knew how this worked in the actual demo. Here's my guess as to the fastest way to do it:

Three pages in VRAM, one for the background, and two for the draw/visible pages.

Steps to draw a frame:
1. Add a row or column of tiles to the background page as needed
2. Fast copy the ...

I am still waiting for an image that shows me what the "wrong" colors actually look like.

Do I still owe you more info on this? Sorry man, I have been very busy with moving to a different state and now getting married, and currently my AT with EGA is a bit taken apart. I have my XT set up with ...

FITF works with real EGA but the colors are wrong.

Thanks. Glad to see you back.

Interesting. :garg What game are you working on?

Not a real game currently. Just an engine. 16 bit, EGA/VGA, OPL2/OPL3, smooth hardware scrolling, tile-based. Like the Keen engines but with VGA and OPL3 support considered from the start. Targeting XT class machines, even though it probably will ...

Putting this here since it may be of interest to the community.

Wrote a bunch of OPL2/OPL3 code for a game engine I'm writing, so I'm releasing this as a standalone player that plugs into that code, since it's rather useful.

Supported file types are IMFv0, IMFv1, DROv0.1, k1n9_duk3's KMF (see ...

Vanilla Keen 1-3 runs fine albeit a bit choppy even on an original IBM PC with EGA, but it should have a turbo XT.

Vanilla Keen Galaxy runs on an 8088 but really needs a 286 to be enjoyable.

With mods, YMMV. FITF in particular tries to run at 70fps by default, which I've found bogs down even a 386 ...

I could do it with enough practice. Maybe I should attempt

Who's going to vote "no" on that? Do it!

I'm not the creator of this tool, but I think the Keen community will find it useful. I tested it on an IBM Thinkpad T41, one of those ubiquitous 2000s era laptops that's completely DOS-compatible *except* for the sound card, making it ...

I return to the forum to announce a discovery I have made.

You can play NetKeen on real DOS hardware over WiFi.

Your WiFi card just acts like an Ethernet packet transport mechanism from the perspective of your software. It doesn't care what medium the packets are transferred over.
