Add the hash toolset to the baseline disk image. Add md2teach so the build can turn a markdown file into a Teach text file at build time. Introduce the Read.Me from the distribution to the GitHub repository as a markdown file so it can be translated to Teach.

Major rework because I am out of code space in the main segment. Move some stuff around in the C code to get them into other segments. Change the network code so that most of its globals are actually allocated dynamically when network functionality is detected. Change the network state machine so the connection is closed and re-opened on each transaction rather than trying to hold the connection open. It was failing during the game because the network is not being polled. Provide some visual feedback if there is a network problem in the game itself.
Re-opening the connection isn't working for some reason but this is getting pretty close to working.

Bump the version to 1.9 since this is work towards v2.0. Add the structs for the messages to a server side high score list. Add the hash tool to the boot image for network testing. The requests will use hashes to validate that they come from the game.

Add the source wav files that I used for the sound samples and add a script which I used to convert them to a raw format that can be played on the GS. That should make it easier to modify the sounds if necessary in the future. Converting the sounds from wav to raw is not part of the build. The raw files themselves are committed in the repository although the build could be changed to generate the raw sounds at build time.

Change the build to put the executable into a 800k disk image and have a separate boot image. This will make it easier to distribute because the 800k disk image is the release. Bump the version to 0.9.1.

This build has the player moving in X and Y directions and with cleaner handling of the dirty tile to remove the inefficiencies. The good news is that there is no longer any performance problem at 2.8 MHz now that the inefficient dirty tile handling has been removed. The bad news is that they player leaves garbage behind indicating some kind of problem with dirty tile marking. But it is close.

Replace the C code which built tables at game launch time with a script which generates these tables at build time. This reduces the start time of the application and saves code space and is a necessary step before adding some new tables to handle the mouse efficiently.

Implement the code to add spiders to the game. From my testing, it looks like 2 seconds after a spider leaves the game (either shot or off the screen), another one is added. Also, once the score is about 5000, the spiders added will be fast. The only spider behaviour I know of which is so far not implemented is as the player reaches higher levels, the spider constrains itself closer and closer to the bottom of the screen.

Hook up the score. Shooting fleas, spiders, scorpions or segments will increase the score. We track the score in two ways. One is just as a 32-bit unsigned integer for doing numeric comparisons on the score (say to the high score list to be implemented in the future) and secondly as a series of numeric digits displayed in a tile. Both are updated.

Add some global data to have a bit mask of tiles which contain a centipede segment. This will allow the update code to figure out if centipede segments are colliding and if so, change direction. Still need to write some codegen for this global constant data rather than building it at runtime in C.

Finish the spider sprites and the explosion sprites. Remove "and" masking from the spider and scorpion sprites because they will be drawn first and will not overlap with anything on the foreground. Split the sprite.s file into a series of smaller files for each type of sprite. Add a file to describe the overall plan for the design of the sprites.
