Jeremy Rand	7382a7f4aa	Just do writes to the DOC when initializing the sound without a read check. The read check seems to fail for the size register for some reason. Bump the version number.	2021-01-24 14:04:49 -05:00
Jeremy Rand	13f8602048	Finish changing the sound code to adopt the new method for modifying registers.	2021-01-23 11:39:01 -05:00
Jeremy Rand	9d42dd3c59	Move to a table based approach for setting up the DOC registers, still have some more sounds to move to the tables.	2021-01-22 17:44:13 -05:00
Jeremy Rand	a7b404c676	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.	2021-01-22 14:41:05 -05:00
Jeremy Rand	25765e6975	More rework from last night of the sound code to adopt new register writes.	2021-01-22 14:15:22 -05:00
Jeremy Rand	0d681e3571	Move more sounds to the new modify and verify method of writing to the DOC.	2021-01-22 00:52:41 -05:00
Jeremy Rand	a4a4b9ae4d	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.	2021-01-22 00:34:07 -05:00
Jeremy Rand	cf85ec4cb3	Update the version information.	2021-01-20 22:33:09 -05:00
Jeremy Rand	14cef25d9b	Mark this build as 0.9.3 beta. I think this project is now feature complete for release.	2021-01-20 22:20:43 -05:00
Jeremy Rand	2a52b21f8a	Fix bug where the flea sometimes would appear before the second level actually started.	2021-01-20 22:14:59 -05:00
Jeremy Rand	815758f3ff	Rework the game logic to support one and two player games.	2021-01-20 00:06:32 -05:00
Jeremy Rand	3a77ba1367	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.	2021-01-18 00:34:50 -05:00
Jeremy Rand	1b7d2e240b	Fix a bug where it was possible for the player to collide with an exploding bug and then die. Change explosions so they are drawn using background colours which do not result in player collisions.	2021-01-18 00:18:31 -05:00
Jeremy Rand	678a9ee104	Add code to keep track of two separate screens of mushrooms for player 1 and player 2.	2021-01-17 14:51:36 -05:00
Jeremy Rand	230d1f344c	Fix the message to print the right player number when there is a high score.	2021-01-14 23:18:52 -05:00
Jeremy Rand	384a9ea233	Make more globals per player and index into them with the player number at game time.	2021-01-10 23:17:05 -05:00
Jeremy Rand	1cd4ccea3a	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.	2021-01-06 23:27:51 -05:00
Jeremy Rand	4700bd9cff	Fix a bug where the collision and collisionAddr writes went to the wrong bank, leading to memory corruption and crashes.	2021-01-06 22:21:31 -05:00
Jeremy Rand	e2e4da9e37	Modify the build to also put a copy of the disk image on my webserver so it is easy to get onto my real GS for testing.	2021-01-05 22:43:00 -05:00
Jeremy Rand	b8ab0d80aa	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.	2021-01-04 22:34:45 -05:00
Jeremy Rand	50c924e1ff	Look at two pixels wide when detecting collisions with a shot. I believe this solves the problem of shots passing through a centipede.	2021-01-03 23:57:21 -05:00
Jeremy Rand	a84d135819	Mark managing a local high score list as done.	2021-01-01 23:15:11 -05:00
Jeremy Rand	3bb4572eb8	Prompt for the initials of the player when they get a high score.	2021-01-01 23:09:46 -05:00
Jeremy Rand	767a8ba9ab	Fix bug in how the old scores are pushed down. They must be copied backwards.	2020-12-31 15:03:08 -05:00
Jeremy Rand	4c7e52af58	Scores are now added to the top ten list of high scores and saved to the settings file. There seems to be a bug with moving all of the other scores down but it is a start. The initials are hard coded to my own for now.	2020-12-31 14:04:20 -05:00
Jeremy Rand	4d6f8d39f1	Change the prompt when the stereo channels are swapped so the user gets some feedback. Display the high score list. Still need to add the code to update the high score list.	2020-12-30 23:10:22 -05:00
Jeremy Rand	6947d8762c	Add a way to swap left and right stereo channels and save the value in the settings.	2020-12-30 02:31:18 -05:00
Jeremy Rand	1cd301548a	Validate the magic number and the version of the settings file. For now, I am not trying to handle backwards compatibility of settings file but it will be possible to do that in the future.	2020-12-30 00:01:58 -05:00
Jeremy Rand	9228f247e5	Add code to load and save a settings file which will hold high scores and some other information.	2020-12-29 23:56:51 -05:00
Jeremy Rand	aee2b26fea	Add some info about how to start a game and quit and make space for showing the high score list.	2020-12-29 14:15:25 -05:00
Jeremy Rand	10a1d075fd	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.	2020-12-29 00:00:39 -05:00
Jeremy Rand	24bce50a6e	Update the todos and the aknowledgements.	2020-12-28 00:52:47 -05:00
Jeremy Rand	acfb7bec13	Add the new icon from fatdog.	2020-12-28 00:48:49 -05:00
Jeremy Rand	8963a9d76c	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.	2020-12-26 15:26:19 -05:00
Jeremy Rand	cdded307f9	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.	2020-12-26 15:03:29 -05:00
Jeremy Rand	3f0578d142	Fix the crashing bug when the previous game ends with the player colliding with the last remaining segment.	2020-12-26 00:31:54 -05:00
Jeremy Rand	dbbdd156e3	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.	2020-12-25 23:59:09 -05:00
Jeremy Rand	a5296ee1b8	Fix the bug where shots can pass through a mostly destroyed mushroom, this time for real.	2020-12-25 22:26:13 -05:00
Jeremy Rand	929343aead	Add a bug for the muddy sound on real HW.	2020-12-25 01:19:19 -05:00
Jeremy Rand	917c5b97f0	Also change the volume to 0 for looping sounds which are to be stopped.	2020-12-25 00:38:58 -05:00
Jeremy Rand	58cc259d67	Track whether the looping sounds are or are not playing with some boolean values.	2020-12-24 23:50:17 -05:00
Jeremy Rand	e80579f983	Add some TODO items and remove the sound TODO.	2020-12-24 00:45:34 -05:00
Jeremy Rand	493473724b	Add some more bugs to the list based on tonight's play testing.	2020-12-24 00:31:39 -05:00
Jeremy Rand	91ce6ada31	Extend the length of the flea sound and describe the spider junk bug some more.	2020-12-24 00:15:50 -05:00
Jeremy Rand	d65a4ca307	Fix the high pitched sound at the end of the flea sound. It was an off by one leading to an extra frequency being played.	2020-12-24 00:02:41 -05:00
Jeremy Rand	9f74cb46b2	Hit the sound GLU registers directly instead of calling the ROM routines for setting DOC registers.	2020-12-23 23:26:52 -05:00
Jeremy Rand	ea49a5d11c	Add the scorpion sounds.	2020-12-23 14:54:17 -05:00
Jeremy Rand	b952d42427	Some cleanup of some dead code for flea sounds.	2020-12-22 23:43:17 -05:00
Jeremy Rand	b432cf654b	Implement stereo sound. Sounds now come from the left or the right speaker depending on where the sound is coming from on the screen as much as possible.	2020-12-22 23:40:21 -05:00
Jeremy Rand	d4d511ee4f	Fix the bug where the "can shoot" indicator was sometimes not cleaned up. The real problem was that the mouseAddress was incorrect on the first frame of the next life. It still pointed to where the player died.	2020-12-22 21:25:20 -05:00
