OK I just fixed it. I don't understand why this works like this, but it fixed it so I don't care that much.
Basically I went to Manage Platforms, I selected the Supergrafx (wrong named one) platform, and then I went to the folders tab, selected the front box art option, then I clicked browse, but instead of changing to a different folder, I jsut left it on the folder that was already selected and clicked okay. Once I exited that menu, all the images finally showed.
P.S - I also have a SIMILAR issue when I add new games, to a platform that I already have games for in Launchbox. Basically let's say I have sega dreamcast on launchbox with 5 games... But then I downloaded 5 more games and I put them into my dreamcast roms folder. if I go into launchvbox and I try to go to Tools>Scan For Added Roms>Sega Dreamcast.... what happens is the Launchbox tells me after scanning, that there were no new roms found.
In order to FIX this issue that I have had evewr since I first got Launchbox 1 year ago, I have to do the same thing I jsut did to get the images to work... I go into Tools>Manage Platforms>Sega Dreamcast>Folders Tab, and then I click Browse on the games selection, as if I were to change the folder where my Dreamcast roms are located... but instead of changing the folder, I just leave it as it is, and click okay and close the window, and then I again go to Tools>Scan For Added Roms>Sega Dreamcast, the only difference is that this time is WORKS.
If you have any idea on how to fix either or both of these issues... anyone... please let me know.
Thanks in advance, and thanks for the earlier intended help ;]
