I finally started hacking this game. So far, i was only able to find two codes.
Dice/Movement Modifier
043F77E3 000000XX
Turns Remaining Modifier
043F77EB 000000XX
Unfortunately, the code has some unexpected results (possibly because it requires a button activator)
for example, landing on multiple spaces in one turn, landing on an empty space to get treasure then landing on the minigame space, allowing the player to claim the minigame space as their island, etc.
Also, with the Turns Remaining Modifier code, it makes it Infinite play, unless you save and continue without codes. This too, also requires a button activator for better results.
i'm currently searching for the values to the Helper cards.
