ROM Hack Problems sending save file with SavSender

[loathsome]

Hi there,

I'm using port 5311 and I'm 100% sure it's open.

Anyway, so I open up SavReciever and then start sending my save file. At first it says

Resolving host...
Resolved to Â10.0.0.4
Connecting to server...
Sending EEPROM contents......
.............Done!
Press A to dump, or B to restore. *PRESSING A*
Detected EEPROM of type 2, size 65536
Reading 65536 bytes from EEPROM...
Resolving host...
Resolved to 10.0.0.4
Connection to server...
Error!

It seems like it cant connect the second time, wtf?

I'm trying to dump my FF3 save-file.

Thanks for your help!

Try using netcat instead of SavReceiver.

 

[loathsome]

Yeah, I've been trying that - or at least, I've been trying to download it ... Please provide me with a link to netcat for Windows, and I'll give you a free cookie. It's impossible to find.

This is from http://www.vulnwatch.org/netcat/ (the site seems to have problems right now)

Awesome, many thanks kazumi213!!

That went freaking fast

Okay, so I have my save file

.. now, how the heck do I get my DS-X to recognize it?

(The save file is located at this link)

I'm feeling that I'm very close now

-wrong,delete-

To quote from the savsender web page:

Once you have the data, you'll need to convert it to your card format, and then install it on the device. This I leave as an exercise to the reader, though, for the R4, I can tell you that you must simply pad the file to 512KB and then copy it to your device.

Okay. I figure I need to convert it to "your card format" - in other words, DS-X format. How the heck do I do that?

 

[kazumi213]

Here you can download your save ready to use on your DS-X. I've included 2 sizes:

If you're using FW 1.1.2: you can use any, but you should be using the 512 kbytes one.
If you're not using FW 1.1.2: You must use the 256 kbytes one.

In any case remember to rename the save exactly as your ROM in the DS-X.

A couple of pics: Your "Continue" and your "Load Game->Slot 1"

Oh my, that is SO DAMN FREAKING AWESOME! Thank you ever so much!
Your save files worked flawlessly.

Please tell me how you did that, as I've got some other games I'd like to do it with as well.

SWEET!

It is very simple.

Just open your dumped save in a Hex Editor and add as many "00" bytes as required to reach the desired size (256 or 512 kbytes).

Example: Your dump size was 64 kbytes, 64 x 1024 = 65 536 bytes. You want to convert it to a 512 kbytes save, 512 x 1024 = 524 288 bytes. Then you need to add 524 288 - 65 536 = 458 752 bytes of 00s (zeroes).

However, be careful next time you dump your save: your FF3 save was underdumped to 65 280 bytes (was missing latest 256 bytes). Usually this is not important (they're just zeroes or FFs that you can reproduce), so you just use the actual size you dumped (the Hex Editor should show the exact byte size) to calculate the required number of bytes to add (in the previous example it would be 524 288 - 65 280). However, those latest 256 bytes you missed in your FF3 dump were CRITICAL for your save to work, specifically the last bytes:

Without those last bytes, your save would be erased upon ROM loading.

 

[Wolfsclaw]

Btw, is there any way to _write_ a .sav file to an original game card?

Thanks a lot, I'll give it a try later

I really appreciate your help.

Yep! SavSender can do that as well. I've tried it, and it works flawlessly.

Hi there, kazumi213!

I just tried to add lots of 00s so my save file ended up as 512KB, but that didn't work. What am I doing wrong?

Thanks!

 

[Wolfsclaw]

So basically I could go out and buy a legit copy of Pokemon Pearl and transfer my .sav file from the illegal rom (175hours spent) onto it?
very cool

Loathsome> Can you put your save file here please ?

Wolfsclaw> That's right

Hi there, kazumi213!

Thanks!

What save are you trying to convert? Is it the same FF3 save you already posted? Because I said that your save was underdumped. It was missing the latest 256 bytes (shown in my previous post). You must add those to your save, then add the required 00 bytes to reach 512 kbytes size.

If you don't add those 256 bytes, your save is erased ("initialized") when loading the ROM.
