Battery saves (.sav) type and transferring between different emulators

Sad Battery saves (.sav) type and transferring between different emulators
I'm trying to transfer some saves from Fire Emblem 6 to my Android device using the Gameboid emulator. Gameboid has not been updated for around a year now, and I fear the dev has since left the project.

As such, I turn to you guys for support and help on this issue. Tongue

Gameboid gives savegame options of SRAM, Flash, Flash 128K, and EEPROM. FE6 is detected as SRAM, and selecting SRAM in Gameboid saves the file as 32K in size (if a new game is started from Gameboid and there is no .sav file already present in the directory). This is not compatible with the VBA-M saves that are 64K in size.

In VBA-M, if I select SRAM + Flash (128K), it still saves as 64K. These 64K size saves can be *read* properly by Gameboid, but they cannot be saved to. Any attempts to save will simply not work; the game will not crash or anything, but the save will just not be overwritten.

Attempting to load the game with the 32K savefile in the same directory via VBA-M results in VBA-M overwriting the save, even though it can load from it properly.

Is this something that can be resolved relatively easily? Any help would be greatly appreciated.

Seems we are creating a 64K Sram file whether the game actually needs that much or not. by the looks of FE it only needs 32K

Thanks for the reply. I did apply an English patch to this game using IPS-Win. Could that be part of the cause?

No, this game uses SRAM in any case.

OK. Now when can we expect a fix? Would this be prioritized at all?

there are worse issues that still haven't been fixed heh.... but a hex editor and trimming off the extra 32k should work

Hm. That would have to be done every time I want to switch around saves right?

RE: Battery saves (.sav) type and transferring between different emulators
I made an account just to post this thank you to both killazys, for making this topic, and Squall Leonhart, for providing the answer.

I had a similar situation as killazyz. I found that Gameboid 2.4.7 could only read Fire Emblem: The Sacred Stones .sav files created from VBA 1.7.2, but could not make new game saves.

Taking Squall Leonhart I used Hex Workshop to delete the last 32,768 bytes of data (they were all 00s) of the .sav file that VBA created, and it worked! Gameboid can now create new game saves.

RE: Battery saves (.sav) type and transferring between different emulators
made an account just so i could post this.

I've been playing Pokemon Fire Red in GameBoid and wanted to move my gaming experience to my pc in VBA.

Using Gameboid ver. 2.4.7
and VBA 1.8.0.600 according to file properties and 1.8.0.511 according to the file name.

settings in gameboid are automatic

and VBA are automatic and 128k.

i copied the rom and .sav file from the sd card and pasted them together on my pc. changed the .sav extension to .sa1 and opened the .gba file. reverse to go back to Gameboid. not sure if this will work with other versions.

an account to post about emulators unrelated to this project?

gj

we don't -ever- provide releases named like that.
