It worked the last time I used it... it's just been sitting here unmolested since then and now today I go to use it and it doesn't boot. Some LEDs light up, the monitor displays a black screen, and there are some pops from the audio output. If I press print screen a few times the display changes to teal.

In this forum (sorry Spanish),

karoshi.msxgamesbox.com/index.php?topic=1140.0

the user nazgul could revive his OCM after an update making the JTAG cable himsef. It seems the process is easy. Write there in English I think is not a problem and contact with him. Maybe updating OCM is your solution.

...but I haven't changed the firmware at all since HRA's 4th update on April 26th. It was definitely working after that

Did you boot it without any external devices attached? Apart form screen and keyboard obviously.
