The typical Phantom development flow is

development of the title -> compilation -> creating the disk structure -> mkisofs -> blessiso -> sign

all steps are obvious besides, may be, creating of the disk structure.

here is the sample disk structure

/
|
+---Phantom.sys
|
|
+---foo
|    |
|    |
|    +--- foo2.elf
|
+--- autostart.cmd

where -- Phantom.sys is directory, supplied with Phantom SDK, just copy it to the root of the disk; foo -- sample directory, foo2.elf -- sample file executable file, autostart.cmd -- script, executed upon disk booting.

In order to sucessfully initialize Phantom SDK one should include following lines in the begining of the autostart.cmd

 !kernel.complete
 !graphics.load
 !sound.load
 !hardware.complete
 !hardware.authorize
 !device.load
 !device.createevents
 /foo/foo2.elf

where foo2.elf -- is name of your main executable, which should start upon disk boot-up.

And here is the sample "Hello world" program.

#include <phantom.h>
#include <stdio.h>

int task1(void * param1,void * param2);

void main()
{ 
  int maintask;
  
  pg_init();
  pc_init();
  ps_init();

  maintask=pk_createtask(task1,100);
  
  while(maintask)
    pk_yield();

  pk_destroytask(main);
}

int task1(void * param1,void * param2)
{
   int m_vbl;
   int m_bitmap;

   m_vbl=pg_createvbl(VBL_DEFAULT);
   m_bitmap=pg_createbitmap(320,240,16);
   pg_attachstream(m_bitmap,stdio);
   pg_vblattachbitmap(m_vbl,m_bitmap);
   pg_applyvbl(m_vbl);
   
   printf("Hello world\n");
   printf("(c) 2006 Felix.\n");
   
   while(pc_padhit(0)==0)
     pk_yield();

   pg_attachstream(m_bitmap,0);
   pg_removevbl(m_vbl);
   pg_vblremovebitmap(m_bitmap);
   pg_destroybitmap(m_bitmap);
   pg_destroyvbl(m_vbl);       
   
   pk_destroytask(task1);
}
