I'm trying to repro Crisis Force using Racer Mini Yonku. I need to add a 2K SRAM chip.
The PCB has a spot for SRAM which I intend to use. I have a MB8464 DIP28 chip from another dead cart that I wouldn't mind rewiring to work in the DIP24 location, but I can't find the datasheets for either the MB8464 or the DIP24 MB8416 that actual VRC4 carts like Gradius II and Crisis Force use.
Some questions:
Can someone point me to the datasheets for these chips? I found some PDFs on Google but they're not exact matches so I don't really trust them.
Can I just use the MB8464 with some simple rewiring if the pinouts don't match?
Does it matter that the MB8464 is an 8K SRAM?
