zcc  +svi -lm -create-app program.c

This will create a .CAS file. Once compiled, run the SVI emulator and load the "tape" with the /r option.

If you are using the Jimmy Mårdell's "SVI" emulator, you can specify the autoload option: svi -tapa adv.cas

Other emulators, in example BlueMSX need the full BASIC command to be typed in: bload "cas:",r

A WAV audio file can be created too, with the following option:

zcc  +svi -lm -create-app -subtype=wav program.c

To run on a 16K machine, you need to move the code origin to the upper half. '-zorg=49200' should be a good option for you zcc command line. Any working address for the 16k model will still work on the 32k models.

A ROM cartridge for the SVI-328 can be generated with:

zcc  +svi -lm -create-app -subtype=rom program.c

and similarly for the SVI-318 as follows:

zcc  +svi -lm -create-app -subtype=rom318 program.c

It should be noted that the SVI-318 has a different memory layout to the SVI-328.

When generating ROMs, the firmware isn't available so to read the keyboard you must add the option --hardware-keyboard to redirect calls to the "inkey" keyboard reading routines.

An auto booting disk can be generated with:

zcc  +svi -lm -create-app -subtype=disk program.c

The .svi image created is a raw image file that is understood by mame. You can load it in Mame with the following options:

./mame64 svi328 -exp sv601 -exp:sv601:1 sv801 -flop1 a.svi

The SV-806 card is supported by the generic console. In a similar manner to the Einstein, switch to mode 10 using console_ioctl

You'll need to start mame with the following options (this includes the floppy interface):

./mame64 svi328 -exp sv601 -exp:sv601:1 sv801 -exp:sv601:2 sv806

Note, in this mode the standard fgetc_cons() driver appears to not work. So you'll need to switch to the inkey driver using: --hardware-keyboard

The SV-805 card contains an 8250 UART and is supported using the z88dk libraries using the API defined in <rs232.h>.

For Mame usage, start with:

./mame64 svi328 -exp sv601 -exp:sv601:1 sv801 -exp:sv601:2 sv805 -exp:sv601:2:sv805:rs232 null_modem -bitb socket.localhost:25233 -flop1 a.svi

Which will boot an SVI floppy containing your application. You can connect to the serial port by telnetting to port 25233

When z88dk uses the firmware to read the keyboard, to disable the click emitted when a key is pressed add the following pragma: -pragma-define:CLIB_FIRMWARE_KEYBOARD_CLICK=0.

z88dk provides a TMS9918a library that allows hardware access to the VDP chip. All graphical functionality supplied by z88dk uses these functions and such is hardware independent.
