File: Takahashi Meijin no Bouken-jima III (Japan)_test_menu.ips (269 B) (info)
Current version: 1.0
Apply the above patch to a Japanese v1.0 ROM. At the title screen, press B to enter the debug mode (only available with patch).
In the US and EU versions, at the title screen set RAM addresses 0xD430 and 0xD431 to the values 0 and 8 respectively (GameShark codes 010030D4 and 010831D4; disable codes immediately after enabling). The debug menu's text will be glitched if accessed this way, however it is otherwise fully functional.
Next to the word Password on the title screen a two-digit hex number will appear. Using D-Pad buttons, you can change number value, and run an option corresponding to this number by pressing Start. Press B to be invulnerable during gameplay. Press Select to exchange the in-game pause menu for a reset to title screen when pressing Start. Both buttons will play jingles. To return to the regular title screen, press A (only available with patch).
Numbers 45, 47, 50, 55, 56, 57 and everything above or equal to 60 is filtered from input, except FF.
|00–3F||Regular levels from a table.|
|40–44||Bonus stages accessible through a hidden egg.|
|48–4F||Hidden(?) levels with goodies and two partners.|
|53||Dragon bonus room.|
|54||Stage advance screen.|
Set number FF to enter the Test Mode menu. All messages are in standard ASCII encoding, but due to lack of font data, there is no regular display on these menus. The patch above fixes this issue by reorganizing the title screen data. This likely means that the early title screen used regular ASCII before the logo was finalized.
There are three options available in this menu: the first is a Tileset Test, the second is an Object Test and the third is a Sound Test. The fourth menu option has no functionality.
Select the tileset number with D-Pad buttons, then press A. Choosing an out-of-bounds index will crash the game. Some tilesets use more tiles than there is space available, so they will overwrite the border. Press Start to return to the Test Menu.
Select the object by pressing on the D-Pad then press Select to display it. While an object is shown, press Left or Right to select animation phases for the current object. Press Select to return to the object selection mode. Press Start while in object selection mode to quit to the Test Menu.
All objects have a constrained number of animations. However, particularly for the player sprite, invalid animations can be selected - which will crash the game.
Select the sound effect/music tune with the D-Pad and press A to play it. To stop the music, select 00 and press A. The first 64 entries are sound effects, while the music starts with index 4x.
