Bugfix provided by Bandit:

  • Certain memory areas are overwritten due to interrupts activated at the wrong time. Because of this, the location of an idol is always lost (thus making the game unfinishable) and the game may also crash randomly. The following patch fixes this problem:

    org $f908
    call $ff99 ; POKE 63753,153: POKE 63754,255

  • Enemies on screen are stored in a data table starting at address $e470, using 15 bytes per enemy, for a maximum of 5 enemies. However the current room number is stored at address $e4ba, which corresponds to the last byte of this table. If there are 5 enemies on screen (which is more likely to happen at the last room), the current room number is replaced with data about the 5th enemy. When it happens, the screen gets corrupted and the player reappears at another room. This problem is solved storing the current room number at address $e4bb instead. The following patch fixes this problem:
