Hello
what following async memory interface is used for in top ?
output wire mb0_addr[18:0],
inout wire mb0_data[7:0],
output wire mb0_oe,
output wire mb0_we,
output wire mb0_ce,

output wire mb1_addr[18:0],
inout wire mb1_data[7:0],
output wire mb1_oe,
output wire mb1_we,
output wire mb1_ce,

at first ,I guess it is for the rom in cartridge before I saw the rom data located at src/core/games

do these interfaces for cpu ram and ppu vram?
