Unfortunately can't install it coz I've prepped the SD card so the EMU68 partition is not visible to Amiga.

Manually i did it a long time ago but should be straightforward like a cd or zip drive , start here https://aminet.net/package/disk/misc/fat95 .....since then i've gotten used to commodities like caffeine and emu68 imager, hope it helps! Otherwise you can always use the imager or targeted distros for pistorm
