Finally I seem to have found the right place - right here

Wandering through the vast realms of the internet a few days now, strugling to find a Hatari version that will run speedy on my Rasperry Pi - not in Raspbian though, but on the mucht quicker RISC OS. This is an older, RISC chip optimized OS that really is quick even on a single core Raspberry Pi (I think it even doesn't support multiple cores). First signs are great, it really IS quick compared to Raspbian. BUT, the Hatari version that is available for it (1.62-2) doesn't run - it raises an illegal instruction exception.
I know that there HAS been a 1.62-1 that ran beautifully on a Raspberry Pi on RISC OS, but that version I can not find anywhere anymore. I seem to be the only one in the world trying this nowadays

Now I even see a 2.0.0 version - so Hatari is still actively developed - nice!
Anybody can point me to either the original 1.62-1 port for RISC OS/Raspberry Pi?
Thanks in advance and keep up the good work!
