Double dragon 2 AGA fixed

[Mrz]

as I want to create 1 floppy disk of this game ,I was trying several cracks in floppy disks for my A1200 and none of them works, not even using relokick 141
there is a ECS fixed version but not works on AGA neither, it seems only works on the A500+ or the A600



does a fixed flopppy AGA version exists?

[Lizard]

Maybe you could use the WHDload package on a floppy?
As I read here http://www.whdload.de/games/DoubleDragon2.html the copy protection actually caused the game to non working on AGA Amigas.

I made a couple of adfs of the AGA fixed WHDLoad version (Zoned).
Please test.

The bad news is that at least 1MB additional fast ram is required on A1200.

It's a tight fit, only 1kb left on the disk.
I had to compress the title mod and use JST to load the slave into RAM as WHDLoad takes up too much space on the disk.

Oh and bloody hell, I didn't know LZX 68000 version can't use -9 parameter for max compression...
Installed 1.21 020 Y2K version instead and managed to squeeze the lzx down so it fits on a standard OFS disk, just barely..

Excuse me, what purpose does it have to create adf versions of a game that then requires more memory than it normally would if loaded from floppies ?

A standard A1200 2MB user will never use that floppy.

[Retroplay]

OP asked for an AGA compatible floppy version, that's all.

And since none of the available cracked versions work on A1200 this is the best I could come up with.

Maybe WHDLoadCD32 could also work on the A1200? Since it's meant to be used for an unexpanded CD32?

good work master

I have been checking your disk and was a good idea to decrunch the game to RAM in lzx then launch it from there
works fine in my A1200 I tested it

btw, for the game to use less memory perhaps there is a way to crunch the game using xpk, whdload support load xpk files , but the program JST you used don't support it

anyways I doubt this game will fit on 1 disk, because also you need to add to the disk xpkmaster.library and whload is larger than JST in size
but who knows. maybe is possible

nope
whdloadcd32 works only on the original CD32 console
Wepl did so on purpose,who knows why

Data files alone wont fit on a standard 880kb floppy, OFS or FFS.
I did try to compress all data files with RNC Propack but that resulted in unsupported or damaged files in WHDLoad.

IIRC that was back when WHDLoad wasn't free and "nagged" for a key but WHDLoadCD32 didn't.

People would just have used CD32 version instead to avoid coughing up the measly 20 quid it cost to register.

data files alone fits on a disk crunched,
I crunched all the files in the dd2_data directory and according to dopus 5 the directory contain now 757.621 bytes
I used the gzip packer from xpk library to crunch all the files
I tested the game crunched running from workbench and works ok

the problem is that whdload and xpkmaster.library must go also on the floppy, which both files adds about 150k to the disk
this game requires whdload v17 which is around 130k, is there a tiny version of whdload?

Maybe combined with http://aminet.net/package/util/pack/PPLoadSeg ?
Then you can pack the xpk lib as well.

this is another good idea , thanks for posting,
I have been testing and it seems pploadseg works for generic files not for whdload

the main problem is that whdload v17 is 130k and don't crunch very well,around 10% only
I copied tha data files to a floppy FFS formated floppy+ xpkmaster.library which is 16k , and left 60k free on disk ( whdload don't fit)
existing a whdload clone with xpk support < 60k :this could work

I finally done an AGA fix for double dragon 2, it works now on a 2 meg A1200
is based on retoplay disk but boots faster and boots like the original floppy
however it comes with a little surprise

[DanyPPC]

That's ok !

So a standard A1200 can play this game.
