Mapping Shamus

eslapion · Post by **eslapion** » Sun Nov 09, 2008 5:05 pm

I am trying to map all rooms of the game Shamus.

Recently I have used my 16/1 slow down solution to sort of cheat the game in order not to get killed so often but it would still be much easier if I could have infinite lives or even better, a way to altogether disable the effect of enemy "bullets" and become invulnerable.

Anybody could help me with that?

Oh well...
I guess I made it without help...

Here it is! The complete map of all rooms of the game Shamus.

There are 32 rooms in all, numbered 0 to 31.

If you make it to room 31 with the blue key then you simply get sent back to room 0 and level is increased to 2. From what I saw, the rooms remain identical on higher levels.

Enjoy!

If you are still interested, the control of life is $87 decimal 135.

The routine who control the decrement of lives is in $A469 (Zone ROM). If you want to remove it, use a hexadecimal editor to change the first group of bytes you find in the file with the valours $C6 $87 $A5 $ 87 for the NOP operator $EA $EA $EA $EA, and you can live for ever

Thank you very much, I LOVE maps since the C64 days (remember adventures and platform games mapped in ZZap?

).

This is cool. I wonder if Shamus could be hacked so that custom maps could be made for the game with a map editor.

I think Shamus it too hard as it is. I can barely make it through 4 or 5 rooms. I need a training version.

In case you succeed in modifying it, it would be nice to save this hacked version for people with low reflexes like me

I did succeed, however it is little help for people with low reflexes like me too.

Because you don't die, the enemies take very little time before becoming very very fast.

You have to die everyone once in a while because the pace of the enemies increase every time you change room without dying. Dying slows them down.

I think the routine which reduces the number of lives also has the instructions that reduces the pace of the enemies.

I believe in order to make Shamus more "explorable", a few more tools would be needed.

Formater's fix in assembly language:

> DEC $87
> LDA $87

replaced with:

> NOP
> NOP
> NOP
> NOP

I would suggest you only replace the DEC instruction (two first NOPs) but leave the second as it is. Otherwise the next instruction whatever it is will pick up the accumulator value from what it was prior to decreasing a life. I haven't investigated, it could be the same value but better be safe than sorry...

This was posted a few years ago.

I thought it might be nice to make this thread more visible to newcomers who like this game.

So... * BUMP *

It would be nice to have a new link for the infinite life hack.

Seriously. I wish someone would make a more playable hack of this game. Unlimited lives!
