I would like to find where a ram adress is used in a rom (SNES) is this possible ? since the ram adress is always the same I guess it is because it is constant in the rom so this would be possible... but I searched with the adress and got nothing...

It doesn't really work like that. Different areas in code access RAM in order to do different things. After all... if the RAM was only accessed at one point in the ROM, there'd be no need to have the RAM at all.

I'm not familiar with the SNES hacking tools... but I'm under the impression that there's a debugger or tracer or sorts for SNES9X (Evil Peer made something of this sort, although I've never used it... not really into SNES). Perhaps it could help you track down what areas in ROM reference the desired area in RAM.

Could you be a little more specific? For example, what is the address? so we have some point of reference. Also, what methods have you used to search for it so far?

what he probably means is how does the things a game appear in RAM when they are needed by the game. that question i have a vague answer to but I am going to refrain of putting my response...

Look for references to the address. Usually a bank isn't specified (unless it's SNES and not bank 7E). If you know ASM it'll be a huge help.
