"Silhouette is an awesome SNES emulator, supporting full sound, transparency and great compatibility in their first release! Although not as fast as SNES9X, it is playable on most recent machines. It is also a project shrouded in mystery--the developers, former Nintendo employees, have chosen to remain anonymous in order to protect themselves from legal action."
Fact or fiction? Some say that this might have been John's way of releasing a new version of SNES 9x before v0.9.5 came out... form your own opinion...
