I've been stalled out on that for a month or two. The PPU has been quite tricky. I'll probably take inspiration from [nesemu1](http://bisqwit.iki.fi/jutut/kuvat/programming_examples/nesemu1/ http://bisqwit.iki.fi/jutut/kuvat/programming_examples/nesem...) for the next rewrite. Related (with screenshot!): http://blog.redlinernotes.com/posts/So-Close-and-Yet-So-Far.html http://blog.redlinernotes.com/posts/So-Close-and-Yet-So-Far.... If I can wind up with a NES emulator that is "fast enough" and 2500 lines of code instead of 75,000 (Fceux) or 150,000 (Nestopia) then I'll be happy.
