SRAM formats between different emulators

Hi, has anyone documented different formats in which emulators write the SRAM?
I'm trying to convert SRAM files from MASSAGE to Kega format, if anyone has any information regarding that it will save me quite a lot of analysis time.
Thanks and advance!

I don't imagine any emulator writes it any differently, it should be a raw block of data.

That's what I'd expect as well, however I've been hex checking both and in Phantasy Star, for example, while Kega only writes 8K, my old saves from Massage writes 32K and some bytes are written way past the 8K boundary.
I'll continue the investigation, there must be some data format difference... but so far I cannot identify it.
Thanks.

Well Massage writes too much whereas newer emulators attempt to detect how much SRAM the game actually use and/or remove the empty 8 KB chunks.
