Hello HN. SIDfi is a single-board self-contained SID file player. SIDfi requires the original MOS 6581 chip or a pin-compatible replacement such as ARMSID. SIDfi plays tune files such as High Voltage SID Collection from a FAT-formatted memory card and displays current tune information on a small LCD screen. Buttons on the LCD screen can be used to control the playback.
SIDfi is still very much work in progress. I am planning to add ability to play specific SID tunes and directories with joystick buttons and improving playback screen presentation.
