Could you elaborate a bit more on what you mean by "SF-memory"? Do you mean SD memory card? Or are you talking about the SNES's own RAM?

I made a cart that loads a boot with menu. if I have a 4MB file with several mapped roms, how do I do the boot menu do the snes start x game. maybe a soft reset after setting the address bus. but how? SF-memory is a cartride from Nintendo.

Oh right, I have one of those. So you've extracted the 512kB block that contains the menu software from one of those carts, and now you want to try to use it on some other flashcart that you're building? nocash has some info on those cartridges and their data layout. Maybe that can be of help to you.

I see u make a lot things with consoles. what i trying do is a simple menu who start a rom at $x address. I think need jump to the address at $FFFC after manually setting the CPU into the same state it was after reset (8-bit mode, carry flag set). This simulates a reset. but i dont know to do this in pvsneslib.
I alread got a menu, but no reset snes. or start call the game at $x location. ><
