Skeleton C (sdcc) project for MSX binaries

Skeleton C project for MSX

Will create a "hello world" program running on MSX Z80 platform and emulated hardware. Following packages are required:

• make
• hex2bin (1)
• sdcc

(1) To compile hex2bin on OSX, download the source. Extract the archive and delete the hex2bin, mot2bin and hex2bin.1 files (they are for Linux). Then go to the directory on the command line and rebuild the binaries for OS X by typing: make To do a system-wide install: make install MAN_DIR=/usr/local/share/man/man1

Compiling

make all      ;Compile and build
make compile  ;Just compile the project
make build    ;Build the final file (ROM|COM)
make emulator ;Launch the final file with openMSX

Check the makefile to select the correct startup file (ROM/COM). Current supported startup list:

• ROM 16kb (init: 0x4000)
• ROM 16kb (init: 0x8000)
• ROM 32Kb (init: 0x4000)
• MSX-DOS COM file (simple main)
• MSX-DOS COM file (main with arguments)

Thanks

• Avelino Herrera Morales for providing the basic files needed to create a MSX-DOS executable.
• Laurens Holst for helping with hex2bin.

skeleton-sdcc-msx's Issues

Possibly missing `bin` directory creation on `Makefile`

First make run output:

mv: rename main.bin to bin/main.com: No such file or directory
make: *** [build] Error 1

After creating a bin directory it's clean:

Binary file start = 00000100
Records start     = 00000100
Highest address   = 0000037C
Pad Byte          = FF
Done.

Possibly misspelled ADDR_CODE position on Makefile for selected CRT0

As seen in 'crt0msx_msxdos_advanced.s', ADDR_CODE must be 0x170, and if 'crt0msx_msxdos.s' is used, ADDR_CODE must be 0x106.
With the current Makefile, hex2bin show 'Overlapped record detected' warning.
