I've begun working on a number of retrogames -- old school DOS games written using Turbo Pascal 7 and assembly, leveraging many modern tools and using DosBox as the testing environment...
But here's the catch... the target minimum system? a 128K 4.77mhz CGA equpped 8088... as in the real deal, genuine hardware. Basically I want these games to work on everything from a modern octa-core monster inside DosBox right down to the original IBM 5150 circa 1982.
The first part was how to handle the graphics -- let's face it, 4 color CGA SUCKS -- but there is the 'undocumented' 160x100 16 color mode. Problem with that is EGA/VGA support, but after investigating I found one solution that was OK... so I expanded it with a big of my EGA knowledge to work almost perfectly on newer cards. The unit I created to handle that ended up being my entry into the 2011 Retrochallenge "winter warmup"
I took that unit and ran with it to make a pac-man ripoff... which in the past five days has gone from 1.0 to 1.3 as various bits got swapped around and optimized (lowering the system requirements from a 8mhz AT back down to my original target).
Includes the full TP7 source code, a readme file in HTML, etc, etc...
Here's some screencaps of it in it's 160x100 16 color glory.
changes from 1.2 to 1.3:
1. Added Joystick Support
2. Tracking of five most recent high scores
3. Saving of high scores to disk
4. New font renderer uses less memory and sped up menu.
5. Fixed bug with MCGA detecting as VGA
6. Fixed audio 'buzz' on PS/2 speakers
7. Fixed PC Jr. blink/intensity not being set right (maybe)
8. Memory footprint down to 67k
System Requirements
4.77mhz or faster 8088
128k of RAM (67,584 bytes free in DOS)
CGA,Tandy/PcJr, EGA or VGA video
System Recommendations
Tandy/PcJr, C/MS Game Blaster
or Adlib sound
Enjoy.

Of course I feel like a right stupid twit -- been promoting the game on various sites for days, and who do I forget to even mention it on? A PASCAL GAME FORUM that I've been a member of for years... DOH!
Had several people comment on how hard it must be to work in such a low resolution -- which is funny because for me 160x100 is high resolution compared to the 128x48 of the Trash-80 Model 1 or the 128x96 of the TRS-80 Coco. (sure the coco could do 128x192, but it was too slow for anything with more than two or three sprites). Hey, if 160x96 was good enough for the Intellivision to be entertaining, why not?
Oh, and if anyone has suggestions -- particularly spots where I could speed up the code I'd love to hear it... or if anything just go over my adlib support, which is pretty dodgy. (while my Tandy/Jr Sound and C/MS support is spot-on)
