I always wondered how the Devs of DaedalusX64 got away with providing thumbnail packs with their Beta 2 and Beta 3 releases. Not only that, they supply a separate download of a thumbnail pack for their Rev. releases. --->
Example (First Post. Under "Preview Pictures:")
I'd like to know if they've found a loophole.
To avoid any grey areas, you could add the feature of thumbnails which is just pointing to a folder, say at: /sdcard/Android/data/paulscode.android.mupen64plus/thumbs/, and users can add their own images (for the games that they own...). Have a default image included, that displays if no thumbnail is available.
I'm just throwing ideas here.
impressive GUI though.
