By the way, there's a possibility that I think would be quite useful : to 
be able to use Hatari's variable as breakpoint condition.

The 2 variables I'm thinking about for now are nVBLs and nHBL, as 
sometimes you know a problem will happen after a certain time, or only at 
a certain line, so doing something like :

VBL=30 && HBL=263 && ( $ff820a ) = 0

would be really cool.

Certainly some other variables could be exported this way, with a simple 
table to associate a string to a pointer to that variable (we could assume 
it's always 'int' size).

Would change the parser and the breakpoint evaluation function, so I'm not 
sure if it could be done before release (Eero ?)
