I am trying to get my RetroCade MegaWing running but am not having much luck; the first thing I did, per the Quick Start, was run the Installer and update the firmware. I did not test it prior to the firmware update. I am not clear if the firmware update worked: I clicked the icon, a window popped up, some text zoomed by in the log area, and then the app closed (I hope - not sure if that's the normal behavior or if it crashed?). Unsure if it had worked, I ran it again, with the same results. I then opened the Dashboard, with the device still plugged in via USB. I checked that the Com Port was set (it was, to 14 - I assume the software figured this out and that I don't need to determine the correct port manually and override?) and then pressed the QWERTY keys, expecting sound. When nothing happened, I tried switching to a different Preset in case the default User one was somehow not capable of producing audio without changes to the settings, and still nothing. I then tried the device "autonomously" - i.e. just connected to a USB power source, not to a PC - I was expecting some kind of boot-up screen then menu on the LCD - all I got was blank characters across the screen, with the top row perhaps a slightly darker shade "box". I am using the wing with a 500K, which I know is not as good as the Pro for the MegaWing, but it should work, right? I had been using the 500K with an Arcade MegaWing prior, but I assume the firmware update made that moot. I have USB selected for the power supply - I was going to try the barrel for "autonomous" mode but couldn't recall/find the DC input specs and didn't want to risk damaging it. I'm really at a loss as to how to troubleshoot...? The one last detail that I wanted to mention: while the left audio jack produces no output, the right actually does: a continual drone - a synth-ish sound vs. something more "problematic" - but it's constant and does not change e.g. with changes to the Dashboard settings etc. Thanks in advance for any help!
