Hacking Any slot-2 devices that don't use SRAM battery?

[Unchi-san]

I'm wondering if theres any slot-2 devices that don't use an SRAM battery for saving? I would ideally like to purchase something that you don't have to change the battery out every couple of years....

Thanks!

As far as I know, all GBA expansion carts use SRAM (volatile memory) to store saves, so they all require a battery. You might be able to find a more general-purpose slot2 device that can store the save to a microSD or internal NAND flash memory, but it would cost a lot more than a few batteries. The EZ 3in1 has internal NOR flash memory, but I'm guessing that's far too slow to store save files to.

Just for info.......

The original SC-CF and SC-SD don't have battery backed ram and relied on a button combo to be pressed to write the sram to mem card. But they are poor GBA carts, so forget it.

To add to sidneyyoung a lot of cards with good GBA compatibility feature soft reset and backups. Resoldering a battery is about as easy as soldering gets though (wire to wire is the only thing easier).

yeah... do you have to have tools to solder though? I have no experience w/ that
