Are there people interested in testing plugin which allows mounting D64 files, making them appear as drive 8? Retro Replay is required, Silver Surfer recommended as there is quite a lot of debug info through serial line.
Current status: load "$" works, but it returns full directory even if you try "$0:t*=p" to list only PRG files starting eith "t". Open+get# works too.
Load "file" works with some wildcard support. Open+get# naturally works too.
Open "#" for direct access is underway. When I get "U" and "B" commands working some games like Ultima 3 should become playable.
No write support yet.
And no, it won't magically start working without RR even if you complain about that. There is 6 KB of RAM used exlusively for buffering, and code takes more than 2 KB already so it wouldn't fit into Action Replay even if I tried.
