To play ROA on hardware, you need a SAMS, which is an expanded memory system for the TI. It's available as a PEB card or a sidecar. Another very useful device is the TIPI, which is an emulation of the entire disk system using a Raspberry PI device. It's elegant and you can transfer files from a PC over WIFI. Both of these high-demand items can be purchased from arcadeshopper.com.
