it certainly seems to work (im not an advocate of mister FPGA like pcn or anything , i just think its mighty convenient to have everythign in place in the size of one soap bar) . with the cheap clones arriving fpga/mister or handheld version have significantly increased the base. Its probably worth checking on release if you have access to one :)
I only have access to an Amiga 1200 with PiStorm and another with a Blizzard and it worked on both. I am also not a fan of those fpga and misters, although I do see the A500mini favorably since it is more accessible to play their games for people who did not have a friend or for people who do not want to complicate things. In the world of Amiga almost everything has a place XDD. A retro greeting!!!
