To compile a program (with 'a.bin' as the default program name), type:

zcc +ace -create-app program.c

The program can then be loaded with the following command:

0 0 bload a.bin

To insert the ANSI VT emulation, and change the default program name, type:

zcc +ace -clib=ansi -create-app -Cz--audio -o program program.c

The '--audio' parameter adds the creation of a 'wav' file in addition to the 'tap' format. Specifying also the '--fast' flag the audio file will be create in a sort of 'turbo' mode.

Setting '-subtype=rom" will provide a very primitive skeleton for a ROM replacement program, be aware that most of the I/O z88dk functions simply won't work, you need to provide your own.

z88dk provides multiple console implementations for the Jupiter Ace - the ANSI/vt100 driver, the VT52/ZX Code driver and a native handler if memory space is particularly tight.

For all versions, redefining the font is possible using the -pragma-redirect:CRT_FONT= command line option. For available fonts see the appropriate section for the ZX Spectrum.

Two graphics libraries are provided:

-lgfxace      64x48
-lgfxaceudg   64x72, currently limited to 64x71 due to a bug

Both graphic modes coexist with the generic console, 64x48 uses UDGs/character codes 17 to 23. The 64x72 mode uses UDGs/character codes 0-31.

Experimental support for the ZX Printer is provided, we supposed it could be attached to the Jupiter ACE via a 3rd party adapter:

To hardcopy the screen please call zx_hardcopy(). The UDG variant will save some memory by printing only the graphics elements, the standard variant will support all the standard text and graphics symbols, in direct and reversed mode.

The appmake tool can be run in "dumb" mode to generate the corresponding audio track of some external program.

C:\>appmake +ace --dumb --audio -b program.tap

The optional "--fast" flag will produce a non-standard audio track which, even if faster, should be still loadable by the real computer.

s l bsave `<name>` saves l bytes from the memory starting at address s as `<name>` 
s l bload `<name>` loades l bytes to the memory starting at address s as `<name>`. If s or l is zero will their value be taken from the file. 
addr call will call Z80 machine code at addr, should be terminated with a jp (iy) Z80 instruction. 

The newer TAP format features an autorun mode, so che 'call' is given automatically.

This target has mostly been tested using the EightyOne emulator, however Mame is also supported. To increase the amount of RAM available, launch with, for example:

mame jupace -ramsize 16K
