Michael Chiaramonte shows us once again how to do some NES Programming.

NES Programming #25 - Status bars and proper scrolling


In this episode we took a page from The Guardian Legend and got a proper status bar working (although there’s no actual data there right now). From there, we started working on how to load rows from the map data as the level scrolled and ran into an issue when I incorrectly thought we had to divide by 8 instead of 32. Oops! Makes a big difference as it turned out. We also covered how some basic 16-bit operations work on an 8-bit processor like the 6502. Thanks for watching! See you next time.
