This is just so beyond impressive. Y'all rock!

You can bet there are not enough CPU cycles left for any game logic.Would it be possible to make it interactive? In other words, would it be possible to make a full port of the arcade machine?
- What mode is made with? Is it also "ANSI from hell"?
- How did you do the vertical scroll, and specially the horizontal scroll, without side glitches (like in Prohibition or Boulder Dash)? Does it has something to do with the overscan? AFAIK, the CGA controller doesn't have a logical width register, like EGA/VGA's, which allows to update the next scroll's column in advance while hidden from sight. So, while CGA lacks this feature, how can this be done horizontal scroll without seen how the columns are being updated on the fly?
The per-frame code really doesn't take all that much CPU time - IIRC no more than ~20% in this version ("profiled" using border-color changes). Should be plenty left for game logic, but the real problem would be all the writing to video RAM, which has to fit in vertical blanking for a 'snowless' display. Combined with the scrolling I don't think it'll handle more than 2 additional sprites of a respectable size. I'd like to make it slightly more interesting in the planned final version, so we'll see.You can bet there are not enough CPU cycles left for any game logic.
Also, the CGA port of the game didn't look that bad. They made good use of the colors.
Glad you liked it!Just got a chance to see the demo in action. I downloaded it Saturday but didnt try till just now. Good thing I D/L it Sat as today the link wouldnt work for me. Dunno. Truly incredible Demo. You guys do great work keep it up!
And maybe its me the but initial chip tune music that plays after the initial Text/color portion in the beginning sounds very similar to Life of a pixel. I know I have spent a ton of hours playing that game. Im not saying anyone stole the music, It just sounds similar and my ear caught it.
Yes those of us that bought the first release got the updated "Super" version free. Its a nice trip down memory lane with graphics and sound from all the vintage computers and consoles. Each "Zone" is themed after the aforementioned equipment. Worth downloading the demo at least.Glad you liked it!
Ha- never heard of that game until now, but apparently there's a 'Super Life of Pixel' now which includes a "CGA"-styled world...

I think Area 5150 will partially run with 512kB but (from memory) it'll stop rather than skip parts when it runs out. I'm not sure how much of the demo you'll be able to see - it may depend on how much memory the version of DOS you use takes up.

*IBM PC 5150 Rev.0 (04/24/1981) BIOS
*IBM PC 5150 Rev.1 (10/19.1981) BIOS
I don't think that people should be referring to the IBM 5150's BIOS' as rev 0 and rev 1 and rev 2. It's just going to cause confusion. For example, in another thread, someone may refer to the "rev 1" BIOS, and a reader interpret the "1" as the first BIOS. I think that we should only use '04/24/81' and '10/19/81' and '10/27/82'.if someone has a Rev 0 or 1 BIOS
Was that in question? 8088MPH ran well on it too.Some good news on the non-IBM front. Area 5150 runs correctly on a Compaq Portable all the way through:(ignore the TV).
Most parts are expected to run well enough on clones, but sections like the end credits are more sensitive to inaccuracies than anything in 8088 MPH was. Some later clones (chiefly ones based on custom chipsets) are already known to have issues. Compaq's are some of the most compatible out there, but it's good to have confirmation.Was that in question? 8088MPH ran well on it too.
