Hey Guys,
I think it's my first post here but hey it's never too late
With the help of Mike I've been able to use a physical drive on the Replay. In addition to the core changes it requires a small pcb to interface the drive and the board (thanks to Jim for the advice on the design!). I've made 2 pcb, one supporting an Amiga drive and one supporting a standard pc drive.
I've uploaded a short video where I boot a few games (+ showing some RTG in 1280x1024) here:

Cheers
