Okay I'm having the same problem as you and it is EXTREMELY frustrating.Take your .sav file, reName it to the samething your Ez-flash iv calls it, put it in the saver folder and click overwrite.
I play roms on my DSTWO and No$GBA, when I want to play on my Ez-flash, I just look at that the ezclient named it (i'm not sure why but if I have a fireRed.gba file, when the ezClient adds it it changes it to something like Pokemon - Fire Red.gab I think it's just reading something out of the meta data, but w/e if it works it's good. I just don't like the long file name on my computer, old habbit, camelCasing is an old habbit too). Anyway so I take my fireRed.sav off of the DSTWO or out of the folder No$GBA is using, I rename it to what it's called on the EZ-Flash. In this case I rename it to "Pokemon - Fire Red.sav" no quotes. Copy that to the saver folder (it might be all upper, SAVER, either way that folder)on my ez-flash and when the game boots it loads that save file.
What happens when you shut your EZ flash off is it stores the games save state somewhere on the card (not sure what part of the cards memory) using the battery, when you turn on; that message, "hold L to skip saving" what it's doing is over writing the save file. So if you do it, the card knows no difference and boots w/e save file it has. Just make sure you were not playing that game last. Like if you were playing fire red. Turn on your system. Let it do it's saving dance. Then shut off and put yoru microSD/miniSD into your computer, and over write it with the save file you want.
I've done this b4. Playing fire red. Want my DSTWO's save on it. Copy that over, overWrite. Turn on EZ-flash, it starts overWriting the save I put on with the save it was storing to write when it turned back on >_< Took me a few tries to figure it out.
@constantgamer247, thanks but I have the same problem and your answer didn't help me.
The problem is that I was playing with the "NO PATCHED ROM" of Pkm Fire Red with VBA. So VBA created a flash 1024k .sav file.
Then, I patch the rom with the EZ Client to play it with my EZFlash IV.
So I have a 1024k SRAM patched save in the "saver" folder
-First Problem: I can't use my Flash 1024k .sav with my EZFlash IV.
-Second Problem: I tried to convert my Flash 1024k save file to an SRAM save file. But now, it's size is 64k and my EZFlash IV says the save was erased everytime I want to play with PKM.
If someone have the solution...
How can I use a .sav generated by the EZ-Flash IV of a patched GBA ROM in a PC? I don't care if it is VBA or NO$GBA, I just want to have the possibility to moves saves from the flashcard to the PC and backwards.
I have managed to run my EZ4 savegame on the NO$GBA. But when I do it backwards the EZ4 doesn't recognize the .sav. Help, please!
1. Either use this program to change the no$gba.ini, or load it yourself in notepad.exe and do the following:
Scroll down the list until you see this:
"SAV/SNA File Format == Compressed"
and change it to this
"SAV/SNA File Format == Uncompressed"
I would suggest using VBA or the VBA-M version, that way you just copy the save file directly to the miniSD in most cases.
