> If you are interested in making smaller files or faster decompression than aPLib, you might look at a nibble-based system. Instead of aPLib's bit-encoding and fixed bit allocation for literal len vs RLE/match len vs match offset, allow the bit allocation of literals vs runs/matches to vary based on the frequency characteristics of the data being encoded.

I'll take a look, but just from the description, the CPU usage might be too high.  At least with aPLib, the CPU time is comparable to the number of sectors that would have been read, so the timing is close to the original.

> I liked your writeup on Conan. I remember playing it quite a bit growing up, but I don't think I got as far in the game as you did. Conan, Bruce Lee, and Dig Dug were the Apple ][ games which influenced me to join Datasoft's engineering team in 1987. Oh and the ray-cast texture mapping they were doing for Alternate Reality.  :)

The first three were favourites of mine, too.  I have Alternate Reality somewhere in the collection, but I've never played it.

The original shows the title very quickly, before performing I/O to load the game.  The 32k file shows nothing at all until it's loaded completely.  It's quite a jarring experience.
