Rockman 8 Trial Version

This is a sub-page of Proto:Mega Man 8.

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Find differences with final version. Also, what exactly paramters in FLAGCHANGE and WORKVIEW do?

The sample version of Rockman 8 appeared on a Special Trial Disc which also contained demos of Rockman X4 and Rockman: Battle & Chase.

Debug Menu#

Use the following GameShark code to open a debug menu:

80106038 E4AC
8010603A 0804

Once used, pause the game to open the debug menu and select one of the following options, or press Select to exit the menu:

FLAGCHANGE#

Changes certain parameters.

WORKVIEW#

Displays the current coordinates of the player as well as some parameters.

VABVIEW#

Your typical sound test menu.

POWERUP#

Allows Mega Man power-up parts (those normally purchased from Roll's shop) to be equipped.

PARTS#

Allows Mega Man's special weapons and some of Rush's stuff to be equipped.

Object Test Menu#

It seems that this menu was developed in a pinch for the Trial Version specifically, as all objects' sprites appear broken in it normally, and all of the sprites also appear to be slightly dithered here (likely owing to the object viewer's video mode not being initialized correctly, or the wrong one being used). Odd because the game had already been completed at this stage, with this version being compiled 6 months after the Japanese PlayStation final version had released.
Use the 2nd code in combination with the 1st one to fix most of the objects.


Use the following GameShark code to open a object viewer:

8010602C 0000
8010602E 0000
80106038 EDBF
8010603A 0804
8010603C 0000
8010603E 0000

Use the following GameShark code to fix most objects in the object viewer (excluding Mega Man, Rush, and the major bosses; player-like objects):

Like the debug menu, pause the game to use it. For some reason, there is a purple box where some text pertaining to status of the object would be shown, but it is always empty.

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: How to display debug text, or rather if there's any debug text display code left in the executable.

Object Names#

The Trial Version contains two lists of object names in the executable R8.EXE, neither of which are present in any final versions of the game:

• The first list (starting at 0x98C38) matches up with the 169 objects that are present in both the Trial Version and all final versions of the game.
• The second list (starting at 0x99538) contains 25 objects that don't appear to be present in any finalized versions of the game, possibly being development objects or placeholders that were removed later, or still existing but not used or referenced by any code in the game.
  

Mega Man Legacy Collection 2 also contains both lists in the PC version's executable despite its version of Mega Man 8 being based on a final version, but the lists there are scattered throughout the executable and placed out of order (though a pointer list could possibly reference them in order).
