more control of some sort.

internally used.


Well, I'm making progress.  I've gotten far enough now that I know at 
least which functions have return values, and how many arguments there 
are.  I built a .so wedge, so now I can watch the function calls as they 
happen while playing back a .rm file!  :)

However, I'm a little worried that the argument structures appear to be 
filled with code references.

Another strange behavior is that there appear to be 4 "CustomMessage" 
calls for every "Transform" call.  I don't like that...

If anyone wants to take a look at the wedge, let me know.  The quick 
summary of what I've learned is:

void (*rv20_init)(unsigned int * info, void ** handle);
unsigned int (*rv20_hive)(unsigned int * info, void * handle);
unsigned int (*rv20_free)(void * handle);
unsigned int (*rv20_custom)(unsigned int * info, void * handle);
unsigned int (*rv20_transform)
              (
                unsigned int input_size,  // +8       read size?
                unsigned int output_size,  // +0       write size?
                unsigned char * input,// +10      pointer test, readable
                unsigned char * output, // +14      pointer test, writable
                void * handle  // +18 esi  source? handle?
              );

transform is a total guess at this point.  And the info structures are 
totally unknown as well.  the init info structure has some obvious things 
like width & height, though.

Agk, sleeping time.
