Its all about easy interface file management - some emulators have hundresd of games - i have masses of music and podcasts, tv boxsets, documenteries, film, internet radio - there's shedloads of everything! - Wiiflow is a bit clunky and ludicrously hard to set up - i think thats where integration with wiixplorer comes in - Firstly path management, no one is going to add that in and wiixplorer can already do it well.Wiiflow has a lot of great features, so many that not all are very well documented. The only thing missing for me would be a way to search the database by keyword.
But with a bit of wiixplorer, wiimc+ love, wiiflow can as a pretty front end for finding and playing your stuff.
