The main program loads the parts of the game as modules into the memory area that starts at 800A0000h. FIELD/FIELD.BIN and BATTLE/BROM.X are stored compressed: each file consists of an 8-byte header followed by gzip data, and the first word of the header gives the unpacked size. The field module therefore occupies 264008 bytes in memory, and BROM.X grows from 1142 bytes on the disc to 1740 bytes when it is unpacked.[^d1]The main program loads the parts of the game as modules into the memory area that starts at 800A0000h.

+The menus are separate files in the MENU directory, and the main program loads each of them to 801D0000h by its number. Each entry of the table at 80048F60h gives the sector and size of one menu file; entry 11 is PATYMENU.MNU and entry 12 is BGINMENU.MNU.[^d1]

−Square left part of its development code in the retail program: the event debugger of the field module ([Field Script Debugger](/games/final-fantasy-vii/field-script-debugger/)), a battle-test screen and four extra main menu commands. The routines and their text are still on the disc; however, the calls, flags or menu entries that would start them are missing or held at zero, and the player therefore cannot reach them.[^d1][^bench]+Square left part of its development code in the retail program. The routines and their text are still on the disc; however, the calls, flags or menu entries that would start them are missing or held at zero, and the player therefore cannot reach them. The largest is the event debugger of the field module, which is described in [Field Script Debugger](/games/final-fantasy-vii/field-script-debugger/). The others are described below, together with the GameShark codes that open them.[^d1]
### Battle-Test Screen (BROM.X)### Battle-Test Screen (BROM.X)
Line 44:Line 46:
The main program selects the module to run next from a mode word at 8009C560h. The code at 800146A4h tests this word for 2 and for 4, and a value of 4 loads battle file 3, BATTLE/BROM.X, and starts it at 800A00CCh. However, no store of 4 to the mode word was found in the main program or in any module, so the battle-test screen cannot be opened in the retail game.[^d1][^bench]The main program selects the module to run next from a mode word at 8009C560h.

However, no store of 4 to the mode word was found in the main program or in any module, so the battle-test screen cannot be opened in the retail game.[^d1][^bench]
−BROM.X calls the main program function at 80025174h from 800A0328h, and no other module calls this function. This function reads controller 1, and the button that is held determines whether it opens the main menu, a shop, the naming screen, party formation or the save menu. When it opens the save menu, it also fills the last 30 inventory slots with 99 of each Source item.[^d1][^bench]+BROM.X shows the word SCENE and a battle number over the title logo. The number starts from the last battle of the field (800707BCh) and is held between 0 and 1023. When a button is held for 9 frames, it repeats every frame. The buttons are read through the main program's controller routine at 8001C808h. This routine places the first data byte of the controller in bits 8 to 15 and the second in bits 0 to 7, and the buttons of the screen are shown below.[^d1][^pad]
−### Unused Menu Commands+Table: Battle-test screen buttons
−The names of the main menu commands are stored as a table at 80049248h in SCUS_941.63. The table begins with the 10 commands that the retail menu shows (Item through Save) and continues with four more names: Uso, Beginner, Uso and Uso.[^d1] Because the menu builds its cursor with only 10 rows, the four extra commands can never be selected. In addition, the Beginner entry is given menu number 0, which is the main menu itself, so even if it were selected it would open no screen.[^bench]+| Button | Action |
+| --- | --- |
+| Up, Down | Battle number +1, -1 |
+| Left, Right | Battle number +10, -10 |
+| Start or Circle | Fight the selected battle |
+| Triangle | Menu test launcher |
+| Select | Return to the field |
+The Triangle button calls the main program function at 80025174h from 800A0328h, and no other module calls this function. The button that is held on controller 1 determines whether it opens the main menu, a shop, the naming screen, party formation or the save menu. When it opens the save menu, it also fills the last 30 inventory slots with 99 of each Source item.[^d1][^bench]
+
+The two lists below open the screen from the field. List 2 places a routine in the unused main program code at 8001CDA4h that corrects the texture page of the SCENE text, holds the number to 0 to 999 and skips the scenes 16 to 19, which hold no enemies. List 3 needs list 2; when L2 and R2 are held on the field, it changes the field's battle request from mode 2 to mode 4 and starts a battle. In the StationX emulator on 1 November 2026, L2 and R2 opened the screen with SCENE 0000, Up gave SCENE 0001, and Circle started the battle.[^bench][^sx]

+### Unused Main Menu Commands
+
+The names of the main menu commands are stored as a table at 80049248h in SCUS_941.63. The table begins with the 10 commands of the retail menu, from Item to Save, and continues with four more names: Uso, Beginner, Uso and Uso. The routine at 8002368Ch builds the menu cursor with 10 rows, so the retail menu stops at Save.[^d1]
+
+A command opens the menu file whose number is stored for its row in the table at 80049450h. Rows 0 to 9 hold 1 to 10, row 10 (Uso) holds 11, which is PATYMENU, and row 11 (Beginner) holds 0, which opens no file. When the row count at 800236ACh and the cursor limit at 80023378h are raised from 10 to 11, an eleventh row named Uso appears under Save and opens PATYMENU. This was done in the StationX emulator on 31 October and 1 November 2026.[^d1][^sx]
+
+
+PATYMENU is a party editor that reads the main program's button word at 80062D7Eh. Up and Down move between the three party slots; Right and Left step the character number of the slot at 8009CBDCh through 0 to 10 and FFh, which marks an empty slot. Circle reverses bit 0 of byte 20h of the character record, which moves the portrait 24 pixels to the right, and Cross returns to the main menu. The file begins with Square's development file paths, and the first of them is x:\master\menu\data\choco.tim.[^d1][^sx]
+
+### Bugenhagen Materia Menu (BGINMENU)
+
+BGINMENU.MNU is the menu file of the master materia trades with Bugenhagen. The field script command menu (49h) stores its type to 8009ABF5h and its parameter to 8009ABF6h, and the main program loads BGINMENU for types 15h, 16h and 17h. Types 16h and 17h, with parameters 0 to 3, are used only in room BUGIN1B; type 16h checks whether the materia of a set are held and mastered, and type 17h takes them and gives the master materia.[^d1]
+
+Table: BGINMENU trades (type 17h)
+
+| Parameter | Materia taken | Materia given |
+| --- | --- | --- |
+| 0 | 21 magic materia | Master Magic |
+| 1 | 16 summon materia | Master Summon |
+| 2 | 7 command materia | Master Command |
+| 3 | None | Bahamut ZERO |
+
+Type 15h calls a third BGINMENU routine at 801D027Ch. Only the debug room BLACKBGB uses this type.[^d1]
+
+### Masamune
+
+Weapon 127 of the KERNEL.BIN weapon table is the Masamune, and its description is empty. The main program loads this table to 800738A0h, 2Ch bytes per weapon. The halfword at offset 0Eh of a weapon holds one bit for each character, and the Equip menu lists the weapon only for the characters whose bits are 1. The Masamune is the only weapon whose bit 10 (Sephiroth) is 1, which gives 0400h, while all 16 of Cloud's weapons carry 0201h. No field script gives item FFh, which is weapon 127, and no shop in SHOPMENU.MNU sells it.[^d1]
+
+The two codes below give Cloud's bit to the Masamune and place one in the last inventory slot. In the StationX emulator on 1 November 2026, the Masamune then appeared in Cloud's weapon list, and when equipped it showed Attack 99 and Attack% 255.[^sx]
+
+```
+80074E82 0601
+8009CE5E 02FF
+```
+
+### Old Character Records
+
+NAMEMENU.MNU holds 11 character records of 84h bytes from offset 904Ch on, and their character numbers run from 0 to 10. They name Cloud "Ex-SOLDIER" and spell Cait Sith as "Cait Seith", while the list that the naming screen shows, at 8EB4h in the same file, spells "Cait Sith". Record 10 is Sephiroth and record 9 has no name.[^d1]
+
+### Test Enemies
+
+The first scenes of BATTLE/SCENE.BIN contain enemies 0 to 9 (without 3). Their names begin with the bytes 70h, 7Ch and 79h followed by the enemy number, and these bytes do not form English text in the US character table.[^d1][^bench]
+
+### Chocobo Race Editor
+
+CHOCOBO.BIN, the chocobo race module, contains a routine at 800A9A94h that reads controller 1 and works on the bytes at 8009D488h. No jal instruction, pointer or address load in the module refers to it. The word at 800A03ECh is jal 800A9D94h, and the bench notes give 0C02A6A5h (jal 800A9A94h) as the change that would call the editor.[^d1][^bench]
+
+### Unused Dialogue
+
+Every room script of the three discs was walked command by command, and a line of text was counted as shown when the mes (40h), ask (48h) or mpnam (43h) command uses it in any room. The 2325 room files hold 12329 distinct lines, of which 643 are never shown, and 554 of these are outside the debug rooms. Of the 554, 345 are close variants of lines that are shown, and 209 have no close variant. Text shown by other routes, such as battle or the menus, would also be counted as never shown.[^dlg]
+
+Among the lines that are never shown are "This is the end of the Test Play." in TIN_1, a document search in the Shinra Mansion in MTNVL6 ("Look, this letter could be in invisible ink"), and the counters "scenario =" and "number of defeats =" of the Fort Condor battles in CONVIL_2.[^dlg]
