RISC OS Emulator

[Prabhjot Singh]

Hi 
I am a student developer from New Delhi, India. I just went through the GSoc 
ideas page of NetSurf and would like to start my contribution journey by 
submitting a few patches. I went through the list of bugs and I wish to submit 
a patch to the bug 0002078: Slow shutdown. 
Which emulator should I prefer for RISC OS or are there any other solutions as 
well?
