It's 1994 and I've just got myself a brand new IBM Thinkpad 755C! It has an incredibly fast Intel 486DX4 CPU running at 75 MHz. I'm impressed. The 20 MB of RAM are plenty for all of my programs. I like the snazzy Windows 3.1 interface. The high resolution 640x480 screen is really nice too. This new ...

Woah, Borland C++ 3 works perfectly! So now I can get to coding. I grabbed a copy of the latest (1.3) Atroxian Realm source code. It also compiles fine and works properly. Right now I'm not looking to do anything huge with the code. I just want to poke around in it, familiarize myself with the struc...

Hello everyone who knows something about cksrcmod: I am going to try to dive into this code and figure out how it all works. I figure I may as well just get my hands dirty. It was easy enough to get it compiling. I'm using Borland Turbo C++ 3, and TASM 5. It compiles just fine. But after compiling i...

OK, so I tested this trick on my 486 and my IBM PC AT (286). On the 486 it works! But not nearly as well as your results, K1n9_Duk3... I wasn't able to get it to surpass 500K. It was grabbing enough memory for any of the big mods to function properly, but only barely. My best results came with JEMME...

Woah!

I vaguely suspected the UMB thing might affect it, but I was not prescient enough to actually try to remove it.

Thanks for figuring this out, K1n9_Duk3. I'll test it on my machines soon.

I guess the memory manager was originally targeted at an earlier DOS version and might have worked with XMS at some point. As I mentioned earlier, I can't get XMS to work either. OK this is interesting. I know Keen has stuff in the help files about "if you run DOS 5.0", probably expecting that the ...

Put this at the end of your patch file and don't use any of the .COM files: ... This patch overwrites unused parts of the old VW_SetScreen, so don't use it without my customized screen update code! This is only to be used in Ocflore, anyway. Thanks! This worked perfectly. After much banging of head...

Yup, COLR.COM uses 386 code.

OK, so... what could be done to make those things work on a 286?

I'm testing the game on my 286 right now. So far: Palette commands don't work on a 286, I guess they require a 386. So I have to run the game manually with ck4patch ocflore.pat, and all the colors look off. Game runs out of memory trying to load the first level. Not a surprise as I have only the def...

Wonderful! I've been waiting for this one.

I'm happy to test for you on real hardware!

Wow... How's that even possible with the doom engine? Since this has become like a really big thing on it's own, I think this needs to become its own thing instead of being an easter egg.

Yes, please, please! I would LOVE to see this as a standalone game!

I've been largely inactive here for a long time, not because I've lost interest in Keen (in fact, I just finished reorganizing my room with a large space reserved for my 486, the only computer in the house that can run Commander Keen the way it was intended), but because life interferes. A lot has h...

This is crazy. Is this something that could be made into a standalone game instead of just an easter egg?

I wish moving TVs about wasn't so physically exhausting.

Granted. This is because your TV has shrunk to the size of a quarter.

I wish for a tree.

@K1n9_Duk3, I'd like to bring to your attention that AR 1.2 now fails to load without a "low on memory" error on real DOS. I've tried with JEMMEX too, which gives me the largest free amounts of conventional, upper, XMS, EMS, etc. Well, I think I found a solution for that. --- Wow, holy crap, man! G...
