Post by jman »

mjvegasa and mjvegas don't have any cheat codes in the database based on 0.259.
And mjveas will work in 0.260 because of dumped internal ROM.

  • "clear credit" : This game saves current credit in nvram. If you use this code, turn off "infinite credit".
  • "winning hand" : This code works in your turn. Not opponent turn. So "tsumo" is available and "ron" is unavailable.
  • "inifinite donden" : "donden" exchanges player tiles and opponent tiles when you press start button.

Thanks added, though I did change it into the same format as used for some other mahjong cheats as it was quicker/simpler to add.
