So, the last one wasn´t the final version. (But this one might be )

What´s new in v1.1:

• added "mix more frames in GB mode" option
  - in Castlevania 2, in the first stage when sprites are in the water, their blinking looks closer to that on a real GB (not clearly transparent or blinking but something in between)
  - don´t know if this feature is useful for anything other than that
  
• added option to load GB1 battery save to GB2
  
• added save state support for GB2
  
• added option to select slower autofire speeds
  
• non-GBC game color palette switching works for GB2
  
• GEST won´t create empty battery save files anymore
  
• fixed Worms Armageddon freezing
  
• fixed Samurai Showdown (and maybe others) sound stuttering
  
• few other minor fixes and changes
  
• tried to reduce cpu usage further (hopefully there won´t be sound problems)
  
• removed a useless video filter
