NES Programming #44 - Adding attributes back

Quote:

After getting the map code working, I rewrote the code to load the attributes into the memory buffer. This involved updating the asset tool to properly remap the metatiles to properly allow for attribute value lookup. In the end, we’re still running with too many cycles in NMI, but we’ll get that fixed on Thursday. Thanks for watching!
