This is a list of how hotspots in RLST match to cursors. "Hints" as to what cursor to use.

short	record_count
variable	records

The record structure is:

short	record_index
short	cursor

If cursor is -1, however, it is like a switch statement, and follows this structure:

short	var
short	num_states

Following num_states is:

short

cursor

The variable is the index of what to use in the table.

-''record_index'' starts at zero and goes up.
-The ''u1'''s all appear to be one of 0, 2, 3, 200, 300, 400, 500, 600, 904, 905, 999, or 0xFFFF (-1).
-However, there are exceptions: sometimes there is sligthly more data than specified by ''record_count''. This seems to only happen when the resource contains a record with ''u1'' = -1, as if that record was a bit longer than 4 bytes. Probably ''u1'' = -1 gives a special meaning to the record and implicitly sets a new record size (which seems to be 12 or 14 bytes). Other records in the resource seem to be regular ones.
