Compatibility
Designed for the MiSTer Aluminum Armor case. Existing case owners can purchase a replacement rear panel separately.
Troubleshooting
No analog video output?
Set direct_video=1 and composite_sync=1 in MiSTer.ini and choose your output:
RGB: vga_mode=rgb (default), vga_sog=0, SOG switch OFF
YPbPr: vga_mode=ypbpr, vga_sog=1, SOG switch ON
S-Video/Composite: vga_mode=svideo, vga_sog=0, SOG switch OFF
Image scrolling/rolling?
Set composite_sync=1 in MiSTer.ini.
Audio connections?
V1.0/V1.1: 3.5mm is analog audio INPUT, mini-TOSLINK is OUTPUT
V1.2: 3.5mm is analog audio OUTPUT
