Fix the last known bug. The "Game Over" screen is now shown when the first of the two players in a two player game runs out of lives.

Start to change the sound code to wait for the doc to be free and to write and then read to verify that the register write succeeded or try again. That seems to cleanup the sound on real HW. I have only done this for the bonus and the firing sound but probably all register writes should be done this way.

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.

Add the ability to use mame as the GS emulator. The mouse works better under mame than GSPlus for this game. For now, I have both options in the launchEmulator script with one of them commented out. It would be good to put this into the base Makefile infrastructure so mame could be selected as the emulator to use.

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 the flea at the right time. This includes tracking the score in multiples of 20,000 and adjusting the number of mushrooms required in the infield before a flea will appear. Simplify the other score based thresholds which are based on multiples of 20,000 to use this test. Add debug which allows me to add 20,000 to the score whenever I want so I can test these thresholds more easily.

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.
