 I really like LaiNES: it's very minimal and compact — but it has several dependencies, so I try to write the shortest NES emulator possible, in a single source file.
 
 ### There's no sound!
-I'm working on it right now.
+I'm working on it right now. You can also check out the `sound` branch, although it's still in a very early stage right now.
 
 ### What do you mean by "nearly complete"?
 I'll say it's complete once I finish implementing the APU.
 
 ### This game doesn't work!
-Check to make sure BadNES implements its mapper. Also, Mapper 7 is known to be especially buggy.
+Check to make sure BadNES implements its mapper.

+### Mapper 7 / Savestates / etc. doesn't work!
+Those features are still in `beta` right now so expect bugs.
