Honoo no Toukyuuji Dodge Danpei (Genesis)


 * Before using any patch code, use 356:60 (Gens/GS) to bypass the checksum check.

Pattern Check Mode (パターン チェック モード)
This is a sprite viewer for player sprites. Apply patch code 450:0018 (Gens/GS), then reset the game. On the first screen, use Up and Down to select a team to view and hit Start to choose. On the second screen:
 * Up and Down scroll between the possible animations
 * B and C selects different players on the chosen team
 * Start returns to the first screen
 * The other buttons appear to do nothing? (TODO)

Parameter Chousei Mode (パラメータ ちょうせいモード)
This allows you to adjust team/player statistics. Apply patch code 450:0030 (Gens/GS), then reset the game. On the first screen, use Up and Down to select a team to view and hit Start to choose. On the second screen, use the D-pad to navigate and B and C to change a value. Each group of three rows represents a character; what each cell represents is unknown. Hitting Start has Danpei's team ("Tamagawashou"? たまがわしょう) go against the selected team on the Easter Island court (apparently with both teams consisting entirely of their captain in every position; see picture), but once the players assemble, the game locks up (TODO).

The other buttons appear to do nothing? (TODO)

Unused Region Lockout
At $474 is an unused routine that sets the initial game mode to the Sega screen on a Japanese Mega Drive and a (unique to this game) error message on other region systems. The routine will only work properly if it replaces the instruction at $44E, which sets the initial game mode. The following patch codes (all at once, and compatible with all patch code systems) will re-enable the routine:

44E:4EB8 450:0474 452:4E71

Applying patch code (Gens/GS) and resetting will start you up on the region error screen without checking the region. Interestingly(?), the region lockout text does not mention the game not working in Europe.
