Hi Brad. Just some questions to help with troubleshooting for now.
1: before you test your RTG resolution do you get the grey Emu68 logo on the screen connected via HDMI?
2: is everything else on the PiStorm working ok? I ask this because I recently removed and reinserted the SD card on mine and it became unstable after months of rock solid stability, until I disconnected and reconnected the PiStorm32 onto the edge connector in my A1200. One of the various symptoms was a grey screen and inability to reset without a power cycle.
