Notes

Known ErrorsBugfix provided by pushHL: <UL><LI> The player is supposed to wake up at 7:54 after visiting 79 rooms, but it never happens due to a bug in the dream state routine. At 39% the second word should update to 'vision' but stays the same. It's very lucky that the game doesn't crash at this point which is down to the program reading $ff, one is then added to it to get $00 and this value points to the second word. $00 obviously points to first option of second word which is 'dream' and is why it stays the same. Here's the bug: <PRE>b102: ld a, (iy+$05) ;first word b105: inc a ;move to next word in list b106: cp $0f ;gone past last word (nefarious)? b108: call nc, $b110 ;yes b10b: ld (iy+$05), a ;no, so preserve word and continue b10e: jr $b0de b110: ld a, (ix+$06) ;second word <----Here is bug should be ld a, (iy+$06) b113: inc a ;move to next word in list b114: cp $07 ;gone past last word (frightmare)? b116: jr z, $b11d ;yes b118: ld (iy+$06), a ;no, so preserve second word, b11b: xor a ;set first word to beginning of list and continue b11c: ret ;player reaches ultimate dream state (nefarious frightmare) ;in normal game this code never runs due to bug b11d: ld a, $13 ;length =19 (nefariousfrightmare) b11f: ld (iy+$07), a b122: ld a, $06 ;set second word to frightmare b124: ld (iy+$06), a b127: ld a, $0e ;set first word to nefarious b129: ld (iy+$05), a b12c: ld a, $01 ;disallow any further changes to dream state b12e: ld ($b0cb), a ;message update b131: ld de, $5801 b134: ld hl, $5800 b137: ld (hl), $00 b139: ld bc, $003f b13c: ldir b13e: call $a6f5 b141: pop ix b143: ret</PRE>There's also a problem with stack so we need to find two bytes to get the extra POP in. The following patch fixes the problem: <PRE>org $b110 defb $fd ;fix original bug, iy not ix org $b0f9 defb $32 ;update normal jump (jp $b132) org $b11d dec a ;a=7 at this point so 1 byte saved here ld (iy+6),a ld a,$13 ld (iy+7),a ld a,$0e ld (iy+5),a ld a,1 ld ($b0cb),a pop ix ;now lose 2 bytes to clear stack with extra pop ld de,$5801 ld hl,$5800 ld (hl),l ;2nd byte saved here</PRE></UL> Modified "BUGFIX" file provided by pushHL (48K version) and Metalbrain (128K version compatible with +2A).
