Opcode reference

138 opcodes are installed in the dispatch table. All 138 have a located handler and recorded evidence; 123 are exercised by at least one script in the game, and 15 are installed but never used by any shipped script.

__sinit_r_script.cpp at 0x003A6AA0 initialises CRadiScript::pfnTable. Symbolic execution of its copy sequence reconstructs the BSS table at 0x003B2D70; the function pointer is the third word of each 12-byte entry. Every installed entry points at a CRadiScript::Command_XX, and every gap points at the shared no-op CRadiScript::Command_xx at 0x002E2E30.

Families

Range	Area
0x00–0x1F	Script control, flags, event values, scene state, windows
0x20–0x3F	Characters: loading, movement, rotation, animation, expression, collision
0x40–0x5F	Background, map, landscape, camera, vibration
0x60–0x7F	2D primitives, textures, sound, movies
0x80–0x8F	Vibration data, dialogue, text output, windows
0xA0–0xD6	Person/schedule system, battle setup, special effects
0xE0–0xE2	Character placement: life flags and group queries
0xF0, 0xFF	Markers and immediate return

Two carry more weight than the rest: 0x14 is the general-purpose expression command and the single most-used opcode, and 0x02 is every branch and jump.

Addresses across builds

Click an opcode for its handler address in each build. Coverage is uneven, and the reason matters:

Build	Handlers with an address
Debug (SLUS-21262 prototype)	138 of 138
ENG (USA release)	133 of 138
JPN (SLPM-65800 release)	133 of 138

The debug build ships a real linker map, so every handler is named and placed. The release maps are derived from it: 85 handlers have bodies that match the debug build byte for byte, and those agree exactly with the addresses recovered independently from each release’s dispatch-table dump; the rest were placed by matching the surrounding code, and the ones checked by hand for these pages (0x04, 0x06, 0xC5) match the debug build instruction for instruction. A missing release address means “not placed in that map”, not “absent from that build” — the handler is installed in the dispatch table in all three.

Opcode	Command	Evidence	Handler behaviour
Script control, flags and values
0x00	end_script	proven	Releases related data in some cases, clears the 0xE0-byte SCR_DATA slot, returns 1. This acts as a script end/stop for StepProcess.
0x01	script_start_stack +1	proven	Script start helper with local stack script data. The low handler-argument nibble is the start mode and bit 0x10 enables an explicit character selector. The first operand word contains the target script id in the low halfword and an optional condition id in the high byte; conditional starts consume the normal two-word condition payload before any explicit character selector. It can check a condition, construct/copy script data, call Command_00 on a target slot, and call SetScriptNumber.
0x02	branch +5	proven	Reads a branch word at SCR_DATA+0x0C. The high byte is a condition id. If nonzero, it reads the next 8 bytes as condition payload and calls CRadiScript::CheckCondition(unsigned char,unsigned long,const SCR_DATA*). If the condition passes, or if there is no condition id, it sign-extends the low 24 bits of the branch word as a relative word offset, writes the new cursor to SCR_DATA+0x0C, and returns 2.
0x03	trigger	proven	Builds an RVTC_DATA-like trigger record from the command stream. Depending on handler_arg_byte >> 6, it registers a trigger in the eight SCR_DATA+0x80 slots, calls CVariousTrigger::Checking(RVTC_DATA*), or clears matching trigger slots.
0x04	script_start +1	proven	Script start/inline-call helper. It can check a condition, call SetScriptNumber, set default character/object names, copy script data, and run StepProcess.
0x05	conditional_end +1	proven	Conditional script end helper. It optionally calls CheckCondition; if the condition passes, or no condition is present, it calls Command_00.
0x06	load_script_file	proven	Reads one script-file operand, optionally forces bit 0x8000, converts zero to -1, and calls CRadiScript::LoadScriptFile(int).
0x0A	change_game_mode +1	proven	Calls CRadiScene::ChangeGameMode(int). If that succeeds it sets a run of config/event flags with CRadiApp::SetConfigEventFlag.
0x0B	script_stop +1	proven	Script stop helper. It can check a condition, resolve a character abstraction, search a script slot, and call StopScript.
0x0D	marker_seek +1	proven	Marker seek. Selector bits in the handler argument choose where the marker index comes from — a direct operand, a run of config/event flags, an event value, or the in-game clock. The marker is located through GetMarkerAddress and the resolved address is written to SCR_DATA+0x0C.
0x0E	WAITING_SETUP	traced	Saves the cursor to SCR_DATA+0x30 and the two argument bytes to SCR_DATA+0x24/+0x25, then calls the callback pointer stored at SCR_DATA+0x2C with (step_arg, extra_word_count, handler_arg, cursor) when it is set. Consumes no operands itself.
0x0F	nop	proven	Immediate return 0; no handler-side behavior.
0x10	clear_flag +2	proven	Reads one u32 operand at SCR_DATA+0x0C. Low 16 bits are the first config/event flag id. High bits are boolean values. Number of flags is (handler_arg_byte & 0x0F) + 1. Calls CRadiApp::SetConfigEventFlag(flag_id, value) for each bit.
0x11	scene_save_env +1	proven	Scene environment save/restore helper. It creates CRadiSceneSaveEnv as needed and pushes or pops radi time enable, map animation, camera halt, ambient, light, character halt/disp, map disp, camera system, and window status.
0x12	time_schedule_value +1	proven	Time/schedule/event-value helper. It can call CRadiApp::SetRadiataTime, SetEventValueForScript, GetEventValueForScript, GetAbstractionCharacterNumber, and CCharacterPerson::TraverseScheduleList.
0x13	radiata_time_enable +1	proven	Radiata time enable helper. It updates time-related bits in Radi and calls CRadiApp::SetRadiataTimeEnable(int,bool).
0x14	expr (assign and calculate) +11	proven	Evaluates two typed integer operands from the command stream, combines them with an arithmetic/logical operation selected by low command bits, then optionally writes the result to config/event flags, script event values, character data, item data, or script-local float slots.
0x15	script_defaults +1	proven	Sets script defaults. It calls SetDefaultCharacter, optionally sourcing the character id through GetEventValueForScript, and can call SetDefaultObjectName.
0x16	battle_acquisition_setup +1	proven	Battle/acquisition setup command. It initializes a global command buffer, writes battle-result/drop fields, and calls CBtlAcquisition::AddDroppedItem.
0x17	battle_character_entry +1	proven	Battle/acquisition character-entry command. It resolves a character id, builds a 0x14-byte record from an optional character selector plus three entry words, and inserts it into the same global buffer used by Command_16.
0x18	party_membership_control	proven	Resolves a character abstraction and changes party membership through CRadiApp::ReleaseParty or CRadiApp::AddParty; one branch edits party slots directly.
0x19	personal_inventory +1	proven	Resolves a personal data record and calls CPersonalData inventory methods including SetPossessionItem, GetOneItemNum, GetItemInfo, GetSpecialItemNum, GetNormalItemNum, and DeletePossessionItem. Can write a result to a script event value.
0x1A	character_equipment +1	proven	Resolves character and item abstractions, then calls CPersonalData::SearchItemInfo and CCharaEquipmentManager methods for equipping, displaying, and reflecting equipment.
0x1B	window_message +1	proven	Large window/message dispatcher. It resolves character, item, and event-value abstractions, may call AttachMessageData, constructs battle parameter objects in some branches, and repeatedly calls CRadiWindowManager::SendMessage.
0x1C	stand_context +1	proven	Stand-position/current-context helper. It reads stand-position data, calls GetAbstractionStandPosNumber when an operand requests abstraction resolution, and writes position/posture fields into the current global script context.
0x1D	FADE_SPEED	traced	Reads one float operand and stores it to the unnamed global at 0x003B266C (next to the Command_1f global 0x003B2678).
0x1E	packing_file_load_or_release +1	proven	Arg bit 0 clear: reads a halfword id and calls CRadiDataCenter::LoadPackingFile. Bit 0 set: calls CFileObject::ReleaseFile on data-center slot arg>>4 when below 8.
0x1F	PAUSE_SPEED	traced	Reads one float operand and, if CRadiApp::WhetherCanPause() is non-negative, stores it to global 0x003B2678.
Characters

0x24	character_virtual_24 +1	proven	Character command with one unresolved virtual call. The handler resolves a character through GetCharacterID/GetCharacterClass2, dispatches a character virtual method, and touches a character sub-manager. The vtable target still needs a dedicated trace before a higher-level label is safe.
0x25	character_sub_anim +1	proven	Resolves a character and performs sub-animation control through CCharacterAnim; one traced branch calls CCharacterAnim::StopSubAnimation().

0xD2	character_script_param_holder +1	proven	Builds or reads a per-character script param holder: battle-team member lists, free stand positions, or child characters, with the result count/element written to an event value.
0xD3	battle_copy_character +1	proven	Resolves a character, calls CCharacterManager::CopyCharacter, and writes a result with SetEventValueForScript.
0xD4	battle_volty_distance +1	proven	Resolves character abstractions, calls CbtlEtc::Script_CalcVoltyDistance and CRadiApp::ProcessTaskReady.
0xD5	special_effect +1	proven	Builds special-effect parameters, resolves up to two character abstractions, and calls CSpecialEffectManager::ExecuteSpecialEffect_Main or CSpecialEffectManager::AbortSpecialEffect.
0xD6	BTL_PLUGIN_MSG	traced	Resolves a character and calls CBtlCharacter::SendMessage with a constructed CBtlChrPluginMsgParam.
0xE0	chara_put_attach_life_flag +1	proven	Resolves a character abstraction and calls CCharaPutManager::AttachLifeFlag.
0xE1	PUT_QUERY	proven	Calls CCharaPutManager::GetGroupTotalFlagNumber, GetGroupLiveFlagNumber, or GetGroupDefaultLiveFlagNumber and stores the result with SetEventValueForScript.
0xE2	PUT_EVENT_VALUE	proven	Reads a group halfword and a value (optionally through GetEventValueForScript) and calls CCharaPutManager::SetGroupLiveFlagNumber.
Markers and return
0xF0	anim_frame_trigger +4	proven	Special opcode whose default cursor behavior consumes only the header. It branches on the command word mode nibble (word >> 28) & 7. Sampled mode 0 records are used with marker_seek; mode 2 resolves a character/person and calls CCharacterPerson::SetSchedulePercent(bits 8-27). Mode 7 sets bit 0x20 in the active SCR_DATA byte. Mode 3 is a no-op to the script stepper: it is an **animation frame trigger** consumed by CCharacterAnim::ChangeFrame_sub (0x002A4A20), which walks the character EVD's marker table, reads each marker's first word, extracts a signed 20-bit frame from bits 8-27 (mode 7 = frame infinity, the end sentinel), and when the playing animation reaches that frame sets the script cursor to the marker and runs AnimationSeqProc(). Bit 31 is the standard keep-going bit. EVDSRC spells these marker id=N (mode 0), anim_frame_trigger frame=N (mode 3), set_schedule_percent percent=N (mode 2) and anim_script_end (0xF00000F0); the remaining modes keep the raw special_f0 form.
0xFF	NOP	proven	Immediate return 0; no handler-side behavior. Because StepProcess already consumed the command header and skips default extra-word advancing for opcodes >= 0xF0, this consumes only the header.
