OK, CD32 all but sorted. Used Liberation, Microscosm  and Lotus Trilogy to find all hardware related issues around akikko and CDDA / timing. Had to pull CDDA mixing off VME and put it back on SC, as it was causing issues with paula audio.

HDF support is working, had some issues as psp toolchain newlib was using wrong fopen and it was causing filesystem to throw a fit. There is an is with RDB HDF though, will look into that, once I check folders are working. I think its the same as other emu's, sometimes you have to format HDF on emulator being used.
Did have a quick go with noRDB HDF, loaded a few WHDload games, all fine, .

Hopefully, will be on GUI soon.
