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) . . . . |
