Building a MBC30 4MB FRAM Flash Cart (Part 2)

It looks like the documentation on the MBC30 chip was not correct. Alex from insideGadgets found out that two of the pins have been swapped in the documentation. Swapping these pins over on my prototype might be good enough but it looks like there is still something else that needs to be done. At least it doesn't crash when trying to save. That's a step in the right direction. The next PCB looks very promising. 

Here is the corrected pinout for MBC30 chips: https://cdn.discordapp.com/attachments/586059516328542218/700864048631382086/mbc30_fixed_pinout.png

Do note that the current version (v1.3.1 as of this video) IS WORKING! Thanks Smelly-Ghost for confirming!
