Jurassic Park - possible to 'rip' level maps from the game? - Page 2

laffer · 09 February 2011, 10:52

Very cool, I never expected anyone to do this so quickly!

Thanks!

Would it be easy to grab the rest of the maps now that you know how to rip them, or would it still be a lot of hassle?

Joe Maroni · 09 February 2011, 22:52

no...there is just only one value left that needs to be changed for each map but i´ll explain it later..

look at HOL....next map done....

it would be helpful to get savestates of the levels to rip the maps...but only from AGA version first...i didn´t checked if the ECS/OCS version work the same way....

These are the level codes for the AGA version.

02-"E54C67AA"
03-"B5A48352"
04-"D5F4AB62"
05-"95B48B42"
06-"85A4834A"
07-"85B48B42"
08-"F54C6FAA"
09-"C57C77B2"
10-"D56C7FBA"
11-"A5149F5A"

Some of them are indoor 3D sections like level 3.

Awesome

By the way, I just noticed the Amiga 1200 Jurassic Park box has 2 screenshots from the SNES version on the back, and only one that looks like the Amiga version (in the middle) -

i know the levelcodes, but i worked with the AGA TOSEC version cracked by Fairlight
after typing the correct code for level 5 it requests for disk 4. inserting the disk, load some tracks and after displaying the title screen the game ends up with a guru....

some working savestates would be useful....

EDIT: tried level 10 and saw it is a 3D section...ripped the overview map of the section with gfxrip...should it be added to HOL ??

PM me your email address and I'll send you the IPF file. The cracked version is buggered!

I think the middle one is from the PC version. There are no Amiga screenshots on the back of the Amiga box. Scandalous! lol.

One thing about the first level of Jurassic Park - it actually consists of two maps, the outside map and a 'sewer' map.

Joe Maroni · 12 February 2011, 19:29

Can I get a savestate of the sewer level?

laffer · 12 February 2011, 22:54

Oh I should have thought of that, I'll get right on it!

Joe Maroni · 12 February 2011, 23:29

i thought to find out the right format that JP use, but i stuck on level 5 and 6 now...

the method i used for level 1 and 3 worked fine, but the next levels seems to work in another way....

never saw this....

Steve · 12 February 2011, 23:31

Sewer Level is in the zone.

Joe Maroni · 15 February 2011, 22:05

hmm...i thought to get it, but it looks like the game works in another way...

map data was found at 890584

i´ve run the data through this code:

Quote:

source$ = RequestFile$("","",0,"")
dest$ = RequestFile$("","",1,"")

s = ReadFile (source$)
d = WriteFile (dest$)

For i = 0 To FileSize(source$)/2-1

value = ReadShort (s)

value = swap_bytes (value)

;;;;
;this is the part that is used to change the format that lvlrip can use it
;;;;
value = value Shr 2

;level1 = $BA
;level3 = $130

If value => $BA
value = value -2
Else
value = value -1
EndIf
;;;;
;end of main part
;;;;

value = swap_bytes (value)
WriteShort d, value

Next
End

;read a short and swap bytes to get the right value
Function swap_bytes (word)
byte1 = word And 255
byte1 = byte1 Shl 8
byte2 = word Shr 8
mod_word = byte1 Or byte2
Return mod_word
End Function

it works fine for level 1 and 3, but at level 5 it won´t work anymore...even the sewer level looks bad....

but i´m still working on it...didn´t tried all methods....

laffer · 15 February 2011, 22:44

Glad to hear you haven't given up

But even if it turns out to be impossible, it's still much better than nothing to have two of the maps

Joe Maroni · 16 February 2011, 09:57

I don't said that it is impossible. It needs only more investigation.

r0ber7 · 17 February 2011, 19:30

wow, nice work on the map for the first level. i remember playing this game, i then drew the maps using the old pencil + paper technique.

well, actually, i remember the sewer level drove me crazy and i gave up, heh.

Joe Maroni · 17 February 2011, 19:42

you could restart playing the game when the sewer level map is available..

EDIT: i´ve added a savestate of level 5 without any tile collision. you can walk on every part of the level. have a look and of course fun with it....

laffer · 18 February 2011, 07:08

Tried out the savestate, nice

This game has quite big maps.

Recording a longplay of the PC version these days, so I had to draw a map of the sewer level (again, I keep losing my old maps

), did it in Paint this time so I won't lose it again.

Steve · 19 February 2011, 17:49

I have just created a couple of maps for Level 3. First is the Ground Floor Level. Second map is Sub Level 1.

The white dot on the first map shows your starting position.

The white dot on the second map shows the level exit.

I will be making more maps of the other 3D sections when I get to them.

Steve · 19 February 2011, 20:51

Why does it say Level 3? Its Level 2.
