Handler behaviour

Branches on handler_arg_byte & 0x1F; calls CRadiSound::LoadEventSeFile or CRadiSound::LoadBattleVoiceFile, and one mode writes a computed value to CRadiSound+0x74.

Encoding

The command header is one 32-bit word, as described in §3 Instruction encoding:

 31            24 23            16 15             8 7              0
+----------------+----------------+----------------+----------------+
|  flags         |  argument byte |  extra words   |  0x74          |
+----------------+----------------+----------------+----------------+

Bits 8–15 give the number of 32-bit operand words that follow. Bits 16–23 are handed to the handler as a bitfield; on character commands bit 0 normally says whether a character selector word is present. Bit 31 is the keep-going bit.

Operand fields

4 documented fields. input fields are read from the command's operand words; derived fields are computed from other fields rather than stored separately.

Field	Role	Meaning
`mode`	input	Handler path selector taken from the argument byte. The meaning is specific to each command.
`resource_id`	input	Identifier selecting which `resource` to use.
`table_offset`	derived	Offset applied to `table`.
`yield`	derived	Pause the script here for one game frame; the next command runs on the following update. Lines without it keep running immediately.

Engine calls

Engine functions this handler was observed calling:
