Build requirements:
-------------------
- gcc or clang (for `mksums` and converting a checksummer to BASIC)
- ca65 / ld65 (for building the individual checksummers)
- petcat (for creating .PRG files from BASIC sources)
Build instructions:
-------------------
To build everything:
make
make is expected to be GNU make, so e.g. on a BSD system, type `gmake` instead
of `make` everywhere.
To build only the `mksums` tool:
make mksums
To clean up:
make clean
To clean up AND remove the targets:
make distclean
make variables:
CC command to execute the C compiler (default: cc)
CFLAGS flags for the C compiler (default: -g0 -O2)
C64AS command to execute ca65 (default: ca65)
C64LD command to execute ld65 (default: ld65)
PETCAT command to execute petcat (default: petcat)
Usage:
------
For creating checksums:
mksums [-s] < input.prg > checksums.txt
creates checksums for the input.prg BASIC program in checksums.txt
-s: allow shifted spaces in input.prg
For typing a BASIC program with checksumming:
- Load the .prg for your target platform
- Type `RUN` and `NEW`
- Start typing your program, checksums appear in upper right corner
- When finished, SAVE your program to disk (never use the datasette!!)
- Reset or turn of computer to deactivate the checksummer
- Load your typed program and enjoy.
