This game is a pretty impressive piece of CGA programming, but there's one thing it doesn't do: exploit NTSC quirks to get 16 colors on a TV/composite monitor, instead of the familiar 4.  Here's how you can change that with a patch and a custom set of converted graphics.

Historical exhibit: a set of 25 floppy disks documenting IBM's creation of an in-house bitmap typeface for the RT PC project (code-named Olympiad).  Contains the original material as received, plus TTF and PNG conversions of the fonts and images.

An archeological riddle: these very early public domain games all have similar title screens, which say "IBM" although they were clearly homebrew creations.  Where do they come from, who made them, and what is that cryptic "mystery code" all about?

Presenting the world's biggest collection of classic text mode fonts, system fonts and BIOS fonts from the DOS-era IBM PCs and compatibles.  Contains TrueType (TTF) and bitmap (FON) versions of the original character sets, and some unicode expansions as well.

Is it possible to get Windows to display TrueType pixelfonts in a crisp bitmap-like fashion?  Technically, yes.  Practically... not really.

Compact just like Windows' Terminal font, but based on the EGA/VGA text mode character sets.  Comes in TrueType and bitmap versions.  Besides good ol' codepage 437, it also supports an expanded unicode charset.

Most Apple ][ emulator screenshots out there completely misrepresent the color and resolution of that machine's composite video output.  Here's how to fix that.

IBM officially discouraged PC programmers from exploiting hardware-specific tricks, since that came at the expense of compatibility.  Then, they went and released a game that did just that.  Here's why it was (artificially) prevented from running on color systems.

Another installment on CGA display tricks - covering the final version of 8088 MPH, determining the model of your CGA card in wetware, the extended 1024-color palettes supported by both models, and some artistic considerations.

Not so new anymore.

Can you take the original IBM PC color graphics board, and force it to display 32 times as many colors as it's officially capable of?  Believe it, comrade!  Here's the in-depth write-up on how we did that in the 8088 MPH demo, complete with illustrations.

Back in 1981, this was part of the original set of software available for the IBM PC on launch.  As it turns out, its roots go even earlier than that - and there's also the easily-bypassed copy protection, and a mysterious check for a BASIC error code that isn't documented anywhere.
