I have a softmodded 4.2u Wii using a USB HDD and have no issues loading games with most recent version of Configurable USB Loader or an older version of WiiFlow. I updated to WiiFlow Lite to utilize the Plugins framework, but I'm having an issue with WiiFlow Lite not loading Wii games from HDD so I haven't even been able to start on the Plugins aspect. It shows all of the game info, covers, etc, but when I try to start the game it tries to load a disc instead. If there is a disc, that's what opens. If there is no disc, I just get a black screen. What's causing it to 'lose' the HD being mounted? It even lets me browse the HD to set directories and view files contained on it, but will not actually load a game for anything.
I'm having to shake the rust off a bit after not mucking around with changing anything about the install for almost 6 years, so it's entirely possible that I've forgotten something basic or am overlooking something obvious, but I have enabled every USB boot setting and disabled every SD boot setting I can find in WiiFlow Lite to try to get this working and I'm not finding a solution. Someone go ahead and school me with an obvious solution so I can deal with the embarrassment and go on about my quarantine.
