Watching registers and other info

Trace allows you to step through the DVD in order and watch how it proceeds and how things change.  On the Trace menu, click Watch and check which options you would like to view.  The options are:

·         Input (see below)

·         GPRMs

·         GPRM labels

·         SPRMs

·         SPRM labels

·         PUOs

·         Registers (GPRMs, SPRMs and Input)

·         All

 

“Input” shows the effect of a command and how many times the register has been set.  At a break in the playback, or if you are tracing in “step mode”, you may also input your own value in the input box to see the effect of a change in a command before you actually change it (note that you must press ENTER to accept the change).  You may input in decimal, hex, ASCII (for language codes) or button numbers.  Illegal/invalid inputs are rejected by PgcEdit.

 

This watch is more comprehensive, adding the registers and SPRM labels.  At the start of your session, the SPRM registers will reflect your virtual player setup.  During the trace, the registers are updated as each command is executed.  Registers not yet used are greyed out.  You can see that GPRM(12) was the last set (it is in yellow) and was set to 0, while GPRMs 2, 3, 5, 6 and 7 haven’t been touched yet.
