As psx-place's own @kozarovv informed us the other day in the NEW section here "The Pulse" we learned of the upcoming changes to 6.61 Adrenaline-3 , which will unlock the power of the on board PSP emulator for your Vita devices with this powerful eCFW that now has full PS1 Support with the ability to launch PS1 Games from the XMB and does have full sound support . This makes Adrenaline a much more complete eCFW for HENkaku enabled devices on 3.60.

  What is Adrenaline? - Adrenaline is a software that modifies the official PSP Emulator using taiHEN CFW framework to make it run a PSP 6.61 custom firmware. Thanks to the power of taiHEN, Adrenaline can inject custom code into the IPL which allows unsigned code to run at boottime.​
  
  IMPORTANT NOTE - For 6.61 Adrenaline-2 or higher, you must put Adrenaline files to 'ux0:adrenaline' instead of 'ux0:pspemu/adrenaline'.
