Subject: Re: The explanation for a class of Quirky Features, and POKEs for m

 

All you have to do is NOP out the "RET Z" instruction and you can
have all these quirky features working in both directions!!

i.e. POKE 37032,0 (for Jet Set Willy)

And it's a similar story for Manic Miner, where wall-blocks at head-
height are detected in both directions:

POKE 36032,0 enables these quirky features going left in Manic Miner
POKE 36091,0 enables these quirky features going right in Manic

Miner

Is there, by any chance, a POKE to turn the leftwards headheight bug
OFF in JSW? I would really like that when making games without quirky
features (i.e. in the purely classical platformgame style).

Also, will this be the same for JSW64? Since I might like to have the
symmetrical headheight bug in Strangel II, to make more scope for
puzzles :)

Anyway, I hope to release a JSW patch for vertical conveyors in a
matter of weeks. I'm about to strip the ramp-handling instructions
out of Willy's horizontal-movement routines - and I might just get
rid of that wall-block detection-code while I'm at it! :-)

Amazing. Do you think you will have one vertical conveyor per room,
like the ramp? Dark Tower (which I plan to make a sequel of)
has 'conveyor ropes' which animate like conveyors and pull you
up/down when you hold onto them. They are quite fun.

Incidentally, here's a map of Dark Tower (the C16 version, which is
the same as the C64 version, only split into 3 sections due to memory
restrictions).

Really well designed rooms it has, doing a sequel is going to be
great fun when I get 'round to it.
