Thanks for the offer, but as I wrote in my patch description:

Given the limited amount of space in the original rom, an exact translation would not be possible. Every piece of text needed to be appropriately abbreviated in order to fit the character limit and maintain cut-scene synchronization.

Nevertheless, I'm planning to add apostrophes by creating special characters (such as 's), so I shouldn't run out of space. I'll also fix some translation mistakes. I'm not sure how to completely get rid of synchronization problems though.

No problem! I'm planning to fix some of the remaining errors if there's enough interest.

In general, I only changed the names. The rest of the translation isn't literal, but the meaning of most sentences is preserved.

Hi,
I've recently created a full English translation patch for the Kyatto Ninden Teyandee game released for NES. Preview and download link available here:
