Hacking Back up SRAM.BIN of EZ 3in1 please!

[MetalMarZ]

--Ok ... it's not the SRAM.bin ... sorry


Here is my problem with my 3in1 Expansion pack and R4 Revolution, Wood; SRAM BIG PROBLEM!: (edited, I already made many attempts)

--"Current SRAM Save (Empty or new state)"; "SRAM save data not found. Can`t process to SAV file"

and I think the most important part since before turning off the console or trying a game the sram shows me that it is not writing the .sav or that there is no .sav file and it will not be able to save.

--Result of Sram Test2:

"Nor Flash id=0x227e2218."

"start SRAM verify."

"verify Err: Add=0, S=74, D=81 (sometimes is 83 or ff here)"

What does it mean? Where or how do I check these error codes?


-- Every time I start gba loader it asks me to put slot 2 as default
--I can not use the slots of the sram for more than pressing the buttons and only starts with the B. Games like Zelda to Link to the Past are damaged slots and I can not continue to play.

-- SRAM.BIN donated : injected clean also did not work

-- The Battery: I replace the battery with the manual tape method which I think is making a good contact and the pins are ok.

The battery is checked and tension is lifted. What I do not know is if there is any program to verify the battery in the 3en1... there is?


--- I clarify that probe things like changing the R4, SD, good formatting, the different programs to verify everything. Patch for games with the EZ CLIENT and GBATA programs; but nothing at all. Also check the RAM with MEMTESTARM and it's ok! (unlike the SRAM error ...)

Yes plase thanks!

@Destructobot uploaded it in a thread but no longer exists that link.

Sorry but could someone upload a copy of your 3in1 SRAM.BIN ?. Since mine is corrupt! please! My model is EZ5C11

I need restore My EZ 3in1!

sram.bin is just save data I think. Getting one from someone else won't fix a bad SRAM.

Like @The Real Jdbye said, the 'SRAM.BIN' is just a full 512k (4Mbits) dump of the EZ 3-in-1's Sram (which is used for saving and some configuration). I posted a file ('SRAM.BIN') to blank the EZ 3-in-1's Sram a couple of years ago. Use 'GBA ExpLoader' to flash it:
https://gbatemp.net/threads/new3in1-works-with-ez-v-menu-but-not-homebrew.403584/#post-5820535

But to be honest, I'd check your EZ 3-in1's battery if you've started to have save trouble. Also read the 'Sram Test' section on this thread:
https://gbatemp.net/threads/how-to-tell-which-version-of-the-3in1-you-have.130659/

...and get the 'Sram Test v2' prog here:

"Ni flash id = 0x227e2218."

msgstr "iniciar SRAM verificar."

"verifique Err: Add = 0, S = 74, D = 81"


and the battery is new. Place it with the tape method. And it is tested in the watch shop. (the pins will be the cause? will not make the contact well on the plate? I doubt it)

the link you passed me sram.bin is down please can re-upload it? (although I honestly thought that .bin image was injected into the 3in1 chip)

talking about the error codes of sram test2 ... I have not seen anywhere that the errors mean ... I just saw that they uploaded the program and tested them ok! .... and the error codes? How can I know that he has my 3en1? does my error code mean?

 

[MetalMarZ]

anyway this message is what is important:
"Current SRAM Save (Empty or new state)"
"SRAM save data not found. Can`t process to SAV file"

you see that the problem comes from this save sram data file ... even perform the ram test with MemtestARM and found no problems in my ram pack ... apparently I have the corrupted files of my sram ..


and I add that I can not select any slot in the sram even if I press A nothing happens. with B loading new game but never recording the game. every start gbaloader asks me if I want to start my cartridge 3in1


it will be the hardware should I give up already?

The link is fine. The 'SRAM.BIN' is attached to the post. Anyway, looking at that error, it's unlikely blanking the Sram will help. Plus the fact you have used the tape method to attach the battery doesn't fill me with confidence, it's just too unreliable. Can you not get someone to solder the battery properly?
There's a couple of users here with the 'EZ5C11' and the same problem:

I can try it but it would cost time money and maybe not change anything like happened to many. And in case of result you believe that all these errors are fixed?


Another message of interest in Pokemon for ex: Change the security memory ...

As soon as you pull the battery, the Sram is cleared, so it's not like you could have permanently corrupted files sat in there. Those messages in GBA ExpLoader can also happen with a depleted, missing, shorted, or badly connected battery. MemtestARM tests the PSram not the Sram. I'd get a proper tabbed CR-1220 soldered in there before abandoning the card. It's just a couple of minutes work for someone who can solder.

 

[MetalMarZ]

I totally agree with you. I'm going for the battery ...

Then we can assign all these errors to the same thing. the battery ... (including the error codes of sram test2, in fact when putting hand in the battery the final error numbers oscillated between 81-83-3-ff for both the option verify and to write, a shame not these numbers can be checked). Besides that I failed my attempt with the SRAM.bin. We made it clear that nothing is stored here so adding files is useless.

I will keep you informed of what is happening. Now look who can weld it.

Thanks guys.

Sorry for the inconvenience once again but is there any way to save the game without needing the battery, directly write to the micro SD? As would be the example of Ez Flash4 with its soft reset with the sequence of buttons and consequently to the writing of the SD card? Thanks

Unfortunately no, you can't soft reset in-game from an EZ 3in1 back to a slot-1's menu to write the save. You need to power toggle the DS/DS Lite to get back to the menu. And without a working battery present, the Sram is lost the moment you switch off.
