@buzz Awesome, thank you Buzz!

@nowarrivinghere there is no ETA.

@BuZz Thanks again! Is it possible that the PSP emulation get much better over time?
Also,
by setting this to fullscreen, will the performance drop? (Scaling Mode or Retroarch custom height and width)

@dankcushions Thanks for the tip, I changed the setting to 5:4via the Configuration Editor, that then made the changes to the retroarch.cfg file and that's now the default when I load games. Interesting that by changing it manually it did not work. Anyway, thanks again for all the help over the past few days. I hope this thread is useful for someone else one day who also wants to use a CRT and really wants fullscreen :)
