Hey there everyone

Recently I came across a game with a battery issue... that would be Ayrton Senna's Super Monaco GP 2. Since the battery has those terminals already soldered to it and I couldn't find one to buy around, I decided to solder one of those CR2032 sockets onto the cart, making a future battery replacement easier. Did all the things, put a new battery and tried saving the options (like control type, language and unit for speed...). However it is sill not saving. I tried with two different new batteries and nothing!
So my question is:
1) Is the game supposed to save the options? Or just lap times?
2) If it is supposed to save game options, what else can I check? The RAM chip?

Thanks!
