ugh checksum,thank you for your answer though,cearp.

if it's not obvious, try and find where the checksum is.
i guess your game saves the time played, so, play the game, wait a few seconds/few minutes and save again, the only difference will be the time and the checksum.

 

[Ranek]

Is there any guide on how to checksum fix? lol
and yes,the game saves the time played


In The Legends of Heroes Trails of Cold Steel (PCSE00786)
Even if I am able to change the stats and level.It will only be a display,and the value will change back to normal after a fight or equipment change...

That's the limitations of the game itself, I have the PS3 version and when I use GG to edit it, the same thing happens. Stats change back after equip/orbment/lvl up change. However it saves after a fight though. So as long as you don't change eq/orbment it should be fine.

Does the stats gaves you the power it should be giving once it saves after a fight?

At least in the PS3 version it does, so with 9999 STR i was doing 99999 damage with Rean. But there are a few battles you have to lose in game, and if you max all the stats, MOV, SPD, DEF etc, you will not be able to lose as the enemy can't defeat you, so I recommend maxing perhaps only STR, ADF, or smth.

oh,it worked ,nice!
Thank you UnfadingOnes

I want to backup my saves before removing my PSN from the Vita, so I can start using questionable apps when they're released. Can I use the guide on wololo to export the saves and then use them after I've removed my PSN?

Hitting big trouble editing Ys: Memories of Celceta. Only change was money, but when I attempted to load, corrupted save. What's more, restoring clean save resulted in dreaded error C1-6427-9, requiring a whole song and dance to get my old data back and working. Any ideas? It looked straightforward as hell, just a png and a dat file, but I stand corrected lol

 

[ness151]

but when I attempted to load, corrupted save

Could be a checksum. I might check it later.

 

[GryphonRider]

Cheers @ness151, I'm finding so many games with damn checksums that need bypassing! Driving me nuts. Thanks

 

[GryphonRider]

If you need a save, I can upload my clean working ones. Unless you've got the game yourself of course lol

 

[ness151]

I've got the game. I'm about to start.

The game has a checksum.

 

[cearp]

it would be nice if someone explained the check sum a particular game has.
i think the only time i had to do anything like that as with oot for 3ds, just something small and gamesquest1 helped me with it
but yeah, i doubt any of the checksums are so crazy. some hex programs are nice and let you calculate let easily.

 

[GryphonRider]

I mainly use Hex Workshop or HxD. I'll see if I can find a good tutorial or something on dealing with checksums

 

[hanseo]

does anyone have a save for god eater resurrection and tales of innocence r to share?

What is a checksum?

what role does it play?

how does one find and "Fix" the checksum?

sorry for all the Q's

a checksum is like...
say the game save data is '012345' (simple yeah)
the checksum could be 'add up all the numbers' - so we would get a checksum of '15'. (0+1+2+3+4+5)
so, the whole savedata, included the checksum would be '01234515'.
when the game checks the save, it does a check on the data and the checksum, so it checks if '012345' actually adds up to '15'. if so, good.
if not, the save is corrupt, maybe the memory card is bad... etc etc. it's not only to prevent hackers.

if we want to edit the game save, for example we change the first byte of data to '99' -> '992345'.
including the checksum, the whole save would be '99234515' - that '15' is the old checksum, we need to calculate it again!
of course in this example it is easy, just add up the number etc...

but it's not that simple for games, we might not know what data is used to calculate the checksum (all the game save, half of it?)
we might not know how big the checksum is and where it is located in the save
we might not know the method to calculate the checksum.

usually it's not too hard i think, many times it could just be some crc/sha/md5 sum i believe, but i'm sure sometimes it is not so simple.

Thanks for the explanation makes a lot of sense.


lucky for me then that none of the game saves i have edited use check sums

The new Vitamin is out.

Theoretically, the plugin module should allow us a great variety of cheats.
