Talk:MMC1 pinout

Tying PA12 low

Based on the description of NES-EVENT (#105), it appears to tie the MMC1's PA12 input low and connect the cart's PA12 to A12 of the CHR RAM. --Tepples 08:31, 12 October 2012 (MDT)

Given the pictures I can find (kevtris, kevtris-via-bootgod; both are component side only), it looks like the PA12 input is likely still connected to the cartridge edge. I can't tell anything about whether MMC1 CHR A12 OUT goes to CHR RAM A12. And when I load NWC in FCEUX and trap all mapper writes, it looks like the game just uses 8KB mode anyway. —Lidnariq 11:41, 12 October 2012 (MDT)
