I following the tutorial by NintenDUINO on youtube for the Multicart with save function The video is not in english so it was little hard to understand every step and things , I was able to burn the rom and soldered it according to the diagram with Mario Worls + Fzero bin and did everything my question is why we are suppose to use more SRAM PCB + i am using Mario All Starts PCB , And the SRAM is 24 pin one and everything i saw on video was 14 pin ones , I used the 2nd pin anyway.
Followed this.
I have made a simple repro before and it worked just fine.
Please help what am i doing wrong here.

Look here, I've already used the same flip-flop chip:

If you want to use it like 2in1 Hi-LoRom (2x16Mbit), just delate connection between pin 9 (flip-flop) and A19 (pin 42 of EPROM).

For 2in1 , connect only one wire of flip-flop chip (pin9 or pin5) to 27c801 pin1 (A19).
Have a great new year !
