To do: Patch might still be incomplete, i.e. missing some of the dummied-out language checks in the code.

The original game featured a complete English-language localization, activated by the game accessing certain I/O registers of the hardware, which was presumably meant for other Asian markets where the system was released. Ver. 1.5 still contains a full English localization, but it has been rendered inaccessible as the checks for the aforementioned registers have been dummied out. Just like the original game, the option to connect to D-Ark digivices is not available when running the game in English.

This patch for the Japanese version will make the game always use the English language mode, by modifying the remnants of said register checks.

Debug Menu

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Can the debug menu still be accessed somehow, or are these strings all that remain?

Beginning at 0x488420 are a series of strings suggesting a debug menu. Around half of these also appeared in the original game, while Ver. 1.5 adds some minigame-related options.
