  • There's a digital clock in the game that doesn't work properly. The time of day reaches 24:59 (instead of 23:59) before returning back to 0:00. Also the day of month restarts at 0 (instead of 1) after reaching 30. The following code controls the clock:#
    9ec1 210000    ld      hl,0000h^9ec4 22c89b    ld      (9bc8h),hl       ; reset time counter^9ec7 21e99b    ld      hl,9be9h         ; clock address^9eca 3e3c      ld      a,3ch            ; minutes overflow at 60^9ecc cdda9e    call    9edah            ; increment/overflow minutes^9ecf 3e19      ld      a,19h            ; hours overflow at 25 -> SHOULD BE 24!^9ed1 cdda9e    call    9edah            ; increment/overflow hours^9ed4 3e1f      ld      a,1fh            ; days overflow at 31^9ed6 cdda9e    call    9edah            ; increment/overflow days^9ed9 c9        ret                      ; exit^9eda 34        inc     (hl)             ; increment minutes/hours/days^9edb be        cp      (hl)             ; reached overflow value for minutes/hours/days?^9edc 2802      jr      z,9ee0h^9ede e1        pop     hl               ; otherwise exit^9edf c9        ret^9ee0 3600      ld      (hl),00h         ; reset minutes/hours/days -> DAY SHOULD NOT RESET TO ZERO!^9ee2 23        inc     hl               ; prepare to increment next one^9ee3 c9        ret
    The time of day bug could be fixed just modifying the constant as indicated above, however this solution would not work properly for savegames that already store a time of day above 23:59. Also fixing day of month requires further changes. The best solution is as follows:#

  • The game stores all words as hash codes in order to reduce memory usage. According to this hash algorithm, code $4467 could represent either 'DESMANCHE' (scrap) or 'DESCREVA' (describe). In practice the game adopted the former choice, defining this code as equivalent to 'QUEBRE' (break). However it also defined action "QUEBRE LAGO" (break lake or scrap lake) which makes no sense, so it seems the author actually intended to choose the latter meaning as equivalent to 'EXAMINE', and also to define "EXAMINE LAGO" (examine lake or describe lake) instead.#Fixed using POKE 42429,11: POKE 47878,11##

    The correct implementation would be as follows:#

  • Function FUNC(53) handles attempt to kill 'COBRA', however it incorrectly checks for location POS(63)="igarape" instead of OBJ(63)='COBRA':#

  • There's no way to visit location "dentro da cabana". Since the word 'CABANA' is not even defined, it's impossible to define an action such as "ENTRE NA CABANA", thus the only possible solution in this case is adding a regular North-South connection to access it.#Fixed using POKE 58396,46: POKE 58433,37
