SA-1 / SDD-1 To Maskrom Snes Wiring help (Translation)

[Ziggy]

Do you think the 36pin maskroms to tsop48 will work in 40pins maskroms e.g yoshi’s island the screenshots i shared above.

I said, if that adapter lines up and is pin for pin compatible then I don't see why you couldn't use it. Baring any fitment issues, such as not being able to lay flat due to a surface mounted cap or interfering with a neighboring IC.

Double check this, but I believe the pinouts match up...

SNES 40-pin SOP mask ROM pinout:


SNES 36-pin mask ROM pinout (I believe it is the same for DIP and SOP, double check this):

Thats right pinout is the same and yea there is one surfaces mounted cap but its not a problems i can easily move it out of the way.
Just waiting for the new tssop compatible adapter i hope it works out
Also ordered those sdd1 and sa1 boards to from pcbway.
