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 $e2ca
    call $ff99 ; POKE 58059,153: POKE 58060,255

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

    org $ff99
    ld iy,$5c3a ; POKE 65433,253: POKE 65434,33: POKE 65435,58: POKE 65436,92
    call $03b5 ; POKE 65437,205: POKE 65438,181: POKE 65439,3
    di ; POKE 65440,243

  • 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:
    org $eabd
    defb $bb ; POKE 60093,187
