Difference between Super Everdrive and Super Everdrive v2

I've post similiar thread about Everdrive MD so it's time to ask also about Super Everdrive.

Krikzz site does not give any difference information. What I can tell from picture FRAM has been replaced by SRAM. Any information why?

Compatibility increases with games? Faster flashing ?

 

KRIKzz posted a thread at his forum.

This thread does not answer my questions I'm affraid.

I was thinking about replacing previous versions of MS and Super Everdrives, question is - is it worth ?

 

I think this thread should clear up any questions.

So now I have explanation about changing RAM type for saves. Now I would like to know which games are working in V2 that do not work with V1.
