Turn on optimizations on the C code to make it smaller. Ran out of code space in the main 64k bank. More changes to the sound register accesses.

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.

Start work on supporting two player games. When the user starts a two player game now, two scores are initialized and the number of lives of the two players are independently tracked. Also, all of the score code has been updated to increment the player one or player two score correct. Still need to implement the logic to save the game state per player and switch between the players on each death.

Add support for pausing the resuming the game. Now, any key pressed during a game pauses the game. Pressing q from the paused game will quit the game and any other key will resume the game. So, quiting with a game in progress takes two key presses. One key press to pause the game and then the user must press q or Q to actually quit.

I believe I have fixed the invisible mushroom bug. I have inspected all of the code which sets a tileType to something that didn't mark the tile as dirty. I believe the problem occurred because the code in update which placed/changed mushrooms assumed that the draw code which then mark the tile as dirty because the bug which caused the change which dirty that tile. But that is an assumption. If the bug is shot, perhaps the draw routine will not mark the tile dirty. So, now the tile is always marked dirty right at the point where the mushroom is placed. I believe this will fix the problem but more play testing is required to confirm I don't see it anymore.

When looking for collisions, treat the lowest collision as the one that counts. Before this, if you had two stacked mushrooms, it was possible to shoot through the mushroom below and "hit" the mushroom above. This happened because the first collision found was the one that the game handled. If the shot ended up being draw across both mushrooms, then the upper mushroom would record the collision. Now, the collision we care about most is the lowest one which should ensure that the bottom mushroom records to collision always with stacked mushrooms. This is similar to the "shoot through a partial mushroom" problem but is restricted to just when the mushrooms are stacked.

Fix the bug where the tiles on the RHS may be marked dirty and accumulate garbage if the player dies on the RHS. Add some more debug for the crashing bug I am chasing. It looks like more than 12 segments have been added so I am adding debug to detect when the number of segments exceeds 12.
