Hudson Hawk demo - is this even completable?

MethodGit · 23 January 2005, 03:53

I'm talking about the demo that came on The One round the arse end of '91. It has to be a strong contender for most irritating game demo of all.

You're racing against a strict time limit *and* you've got to grapple with the game's complete lack of inertia control, slipping and sliding round platforms and making pixel-perfect jumps and timing your ball throwing tactics carefully. I did get quite far and went as fast as I could but it looked like there was still a good deal of the level left when the timer got to zero and the Amiga gurued (like it always seemingly does when it's time up - an unfinished build perhaps?).

Tell me, has anybody EVER managed to beat this bloody thing? Is there an actual ending?

why not get a replay rom and train the game to stop the timer decreasing

If I had any knowledge whatsoever of Action Replay and how to patch games with it I would.

Perhaps you could teach me how to disable collision detection in the demo as well?

right I managed to find the location in memory and to disable the timer

All I need to do now is figure out how to save it to disk

The main .exe is compressed but I'm not sure about what with...

Maybe one of the experienced programmers can briefly explain how I go about finding out where in memory the program first loads so I can save it to disk/edit it and then re-pack it

Usually it's simpler to leave the original file alone and add a different loader:

1. LoadSeg the file
2. Patch the part after the decruncher so it returns to your code
3. Let the original code run - it'll return to you after depacking
4. Alter the bytes you need to disable the timer
5. Restart the game code

Depacking and repacking the files is a pain and this principle is used by most trainer makers. They often copy their code to very low memory like $c0 or $100 and that is pretty safe. And it means you don't have to change the original file, repack etc...

Well I got absolutely no programming (asm) ability so until I figure that out this is a no go (and this is something i'd like to learn

)

Anyway Meths if you get yer ass on IRC sometime I'll go thru with you disabling the timer with the replay

Well
I have finished Hudson Hawk with no cheats.

So.. erm... it's not all that uncontrollable

. But I have never played the demo, so I dunno
