does anyone know
how to convert SAV files offline
with a PC app without internet
also
that can detect a SAV type
so i dont need to know where it came from

anyone??
thx!!

Prior to Shuny's site (others reading I am sure you know the site but http://shunyweb.info/ if not) there were several tools boasting conversion abilities although their names escape me (I do remember enough to know that none were as in depth as Shuny's site as I recall Shuny pulling apart the DSx and no$gba formats), cory1492 did some for action replay/datel formats if you poke around his site: http://nds.cmamod.com/download.html
I prattled on about some save formats the other day as well if you feel like swinging a hex editor:

edit: It was outphase's tool that I was mainly thinking of: http://forums.maxconsole.net/showthread.php?t=26252 aimed mainly at the GBA slot G6 devices but it is a start.

thx fast
i tried to download shuny converter to PC
but it doesnt work without internet
!!!

i wish i could like save the whole site to PC
or find some other offline converter
oh well

also

i still want to figure out the 6 formats:-
EZV\RAW
CycloDS\M3\R4
Ninjapass\NCard
DS-Xtreme
EZFlash IV
No$GBA

when i open them in winhex
theres almost no diffrence
i cant see what makes them diffrent!?

how is it possibly to ever know what SAV it is???

there are no difference if your looking for that

you can use a sav thats from an r4 on an ezflash V and vice versa. all uses the same type of sav file there is no main difference of its .sav its an .sav and nothing else and therefor can be used on any unit that uses .sav files to save.

sorry if i sounded abit angry in the post but im not angry just tired.

there must be some diffrence
becuz SAV that works on EZV
dont work on cycloDS
and vice versa
tried already
and then why all the options at shunys?

I know the different cards use all manner of naming options (rom name in FAT, rom internal name, bastardisations of serials, list of names) and extensions (.sav, .duc, .gss, .0, .01, .2...) but as you asked

Exceptions are for things like the second daigasso game with Flash - 64 Mbit.

EZV\RAW
Two types of EZ5 save- the 512K padded save used by most other cards (see below) and the savelist era which are just padded saves without the sometimes quite considerable (64kbit (8kbytes) is not a typo) padding.

CycloDS\M3\R4
As far as I was aware all three are the same (M3 and R4 certainly are) as the padded 512K save.

Ninjapass\NCard
No comment as I am entirely unsure about these.

DS-Xtreme
They are noted for having compressed saves (standard LZSS if memory serves- quite a thing when you consider 25 games can easily waste enough space for another game) but it is able to accept raw saves if you give them to it. I saw something about a compression tool in a few of my casual searches earlier today.

EZFlash IV
See R4/padded saves but replace 512 with 256. Same with most other GBA slot era devices (pokemon was the first game to be shown to use 512K and so things changed for the upcoming DS slot devices).

No$GBA
I am told it is a very odd format (one requiring at least some thought to reverse engineer) and I am unaware of any public specs on it.

Datel and the like: usually just some padding at the start of the saves, cory1492's tools are open source if you need specifics.

Oh and for the record Shuny's site runs on PHP so you likely have to have PHP running anyhow. You should still be able to run a reverse engineering exercise with it though.

okay thx fast
i figured out there are 2 types of SAV
and these 2 types only vary on how much padding
i took FF3 SAV and converted to each type from shunys:=

CycloDS\M3\R4\No$GBA
padded up with FFs
CRC32:(B30EB6FF)

EZV\RAW\Ninjapass\NCard\DS-Xtreme\EZFlash IV
padded up with 00s (or not padded?)
CRC32:(189C3C49)

padding:=
EZV\RAW -> 512K
CycloDS\M3\R4 -> 512K
EZFlash IV -> 256K
Ninjapass\NCard -> 256K
DS-Xtreme -> 256K (/compressed)
No$GBA -> 512K (/binary?)
Datel ??? (padding before header?)

thats about it!!



you mean i need to create some local server on my PC to run the site??
i just tried to save the site from Firefox and IE
when i try to convert offline
it just tries to access itself online

really need a universal offline converter
or figure out how to easily trim/pad with hex editor

couple more things too

i downloaded a Sonic Rush SAV that is 8kb
it appears to be padded with FFs up to 8kb
but it also contains a lot of FFs and 00s in the file

when i convert it back from a padded one (cyclo)
its still 8kb again
leads me to believe among EZV\RAW\Ninjapass\NCard\DS-Xtreme\EZFlash IV
that some of these can have unpadded SAV files
but like a ROM it MUST be padded to 8 16 32 64 128 256 512

this is where it gets confusing
otherwise i could just do it with winhex
convert a SAV with just winhex
