22a5feb2a1 level loading colors with memory saving
loading colors was done in a dummy way by reading color of each tile
from the RLE array; but actually a tile always have the same color, then
this info is redundant; anyhow the character set had to be reshaped
properly in order to make easy infer the tile color from the tile value

68456fe39e Memory segments relocation and exposed bugs
- Declared uninitialized segment in zero page: used assembler directives
to reduce errors probability and improve code maintenance; now zeropage
variables addresses are automagically computed by assembler
- Added other debug messages, and rewritten some cycles for good readability and good software engineering
- Fixed more uninitialized stucture bug (maybe I had some sawdust in my
brain when I did this?)
- Fixed concurrency bug in home screen

299eee1257 Reorganized memory
Now program takes less space in RAM.
All variables, costants and Lists are moved before the SID song,
in a previously unused space (BASIC RAM).
SID song edit has been changed:
	- same song but slightly different
	- takes up a bit less than 4k
	- more catchy :-)
	- perfectly fits in $1000-$2000 and allows...
...the new custom charset to be put at $2000!
	- Taken TGGS font and properly customized with tiles
Now actual program starts at $2800.

Also added some useful code for assembler to output debug infos when
assembling with -DDEBUG=1

In the meanwhile discovered tremendous subtle bug due to uninitialized
structure (listX and listY). Fixed.

Memory map now is:
	+-------------------------------+
0000	| things in zero page		|
	|	and low RAM		|
	+-------------------------------+
0800	| BASIC autostart		|
	| then data (variables,		|
	|	costants and strings)	|	<-- this can be done better using segments. Reminder for the future.
	|				|
	+-------------------------------+
0E00	| listX				|
	+-------------------------------+
0F00	| listY				|
	+-------------------------------+
1000	| SID song			|
	|				|
	|				|
	+-------------------------------+
2000	| TGGS Custom font charset	|
	|				|
	+-------------------------------+
2800	| ACTUAL CODE			|
	|				|	<-- plus some garbage data, see above (segments TODO)
	.				.

70b041cf14 Improved graphics
- Added multicolor graphic mode with custom charset, for text and tiles
- Added some debug options in Makefile

NOTE: code is functioning and correct, but really needs a big cleanup a
logical reorganization!

0932566285 Edit status bar text
- Removed debug infos (commented out)
- Added score label

a1382611bc Joystick support (port#2) 2018-09-05 22:53:18 +02:00
a15c924d53 Added skeleton for multiplatform development
Just added some preprocessor instructions and some sample code to show
how to use them. This should be useful for the future port on C16.

e177fdcd86 Added techniques of good software engineering - well, use of costants instead of magic numbers for statuses, sort of enum 2017-12-27 18:12:18 +01:00

ceeea2deb8 Added a lot of useful comments to document this code for future reviews, for future me, and for other mads who still code for the 6502 inside a CBM64 2017-12-24 17:26:33 +01:00

c81b92c960 Improved intro.
Improved introPrint.

Adjusted gameover routine to work with the new intro.
This needs to be further improved anyway to give a sensible delay before
clearing the screen (to allow player to see her/his score)
2017-12-24 15:57:37 +01:00
1d7226df45 Reorganized code with statuses, to introduce an intro scene.
Added routine to print text during intro; things needs to be developed.

207cbfd3cf That old X,Y coordinates generation using that ugly way was a real sh*t.
Now it is ways better (it simply does `random number` modulo `screen rows`
- or columns, depends).

There also was an error in comparing snakeX,Y with new piece of food's X,Y
Now really fixed (I hope, at least, since the bug is terribly difficult to
reproduce)

Also improved printing routine: now it can print general hexadecimal numbers,
and can locate them everywhere across first line (and beyond also, since it
is not checked, but if you do, you are a moron). Simply put byte to be print
in accumulator, column in Y index, and then jsr.

61a1c140f4 Probably fixed rare bug:
the pseudo-random routine pseudo-randomly generated X,Y for new piece of food
that corresponded to immediately next snake head position.
This X,Y resulted empty when checked in the routine, but suddenly after it
is overwritten with snake head, so food simply disappears.
This leads to impossible game play, because no new pieces of food are
generated if no food is previously eaten, but there is no food to eat, so...
Hope to have fixed.
