Hi there, I want to use a MAX795 chip on my new SNES cartridge board that uses new chips. Although the game works 100% OK on my cart, it crashes completely at the time when the console wants to read from SRAM. I used MAX795 chip for this purpose and I suspect this is the problem. I checked several SRAM chips and the effect is exactly the same every time...

Here's how I connected the MAX795 chip. Is this correct??

It works completely random with random glitches but it almost never works and I'm really out of ideas... At least BA6162 chip worked fine but unfortunately I ran out of them and I only have MAX795 right now that doesn't work. Here's the datasheet just for the convenience: ... AX795T.pdf

Anyone have any kind of suggestions?? Please for reply. Many thanks in advance!!

I'd be interested in such logic, too.
I want to make my own board with this as well.

As for your problem, I cannot help much but maybe try this:
Original Pinout:
                 __  __
            OUT |01\/24| BATT
            VCC |02  23| /RESET
        BATT ON |03  22| /CE OUT
            GND |04  21| /CE IN

Pinout for SNES:               
                 __  __
       SRAM VCC |01\/24| 3V BAT w. 1k Ohm Resistor
            VCC |02  23| NC
             NC |03  22| SRAM /CE
            GND |04  21| Cart #26
