Are you trying to use this for Pokemon? If so, it doesn't work.

 

[timrid2000]

yea i am want to use it on pokemon is there one out there that work with pokemon

 

[DeMoN]

Nope sorry. It's not the converter that's incompatible, it's the Action Replay.
The Action Replay save backup/restorer will not work for any game that has a 1MB game save, like Pokemon.

 

[timrid2000]

action replay lets me back the file up and when i take it off of action replay and put it on my computer it is 517 kb

The key is in the extra 5 kilobytes- as I recall duc is just raw sav with a nice header. I have long forgotten the contents of said header but it would not be too hard to pull apart.

cory1492 made an app once that did conversion but he seems to have updated his site and I can not get at it.

Try with a couple of duc saves from gamefaqs or something to figure out the format.

 

[timrid2000]

my problem is when i convert the .sav back to .duc the file size is wrong it is 256 kb and it needs to be 517kb for action replay to load it back in to the game

 

[FAST6191]

I do not doubt it is the problem, that tool should allow you to figure out the format though and allow you to manually correct for it.

 

[timrid2000]

all it does is make a copy of the file and put a .out at the end of it.

That is my chosen save for this example.

Looking at it the main save starts at 1F4- everything before that is the action replay's header section.
The simple way would be to grab a save file (any save file) from the game you want to fiddle with, grab that header and stick it on your raw save (you can just do a "copy /b header.file+save.sav actionreplay.duc if you do not want to use a hex editor beyond the intial grabbing of the save).

If you wanted to go a step above then you can make your own header- the first line looks important while the other two are just the game name and a comment in first unicode and then plain ASCII (two very common encodings), that is as complex as it gets by the looks of things.
