THESE DLL'S AND THE ASSOCIATED FIRMWARE ARE NO LONGER RECOMMENDED!

The custom firmware utilised with these DLLs has some pretty severe bugs, mostly around slider processing and sensitivity configuration. A new, better firmware has been released, that fixes these issues, and no longer requires the use of IO DLLs, as it emulates the real arcade hardware directly.
