Thanks for the reply, my friend, but I've walked away from this product, now - so many bugs with it that I've had to spray my computer with RAID.
Going by the name, and the cost, I think it's perfectly reasonable to expect LB to be able to be simply pointed at a tree of subfolders containing game files, and have it select the right emulator and parameters, and then go and run it. It's not that difficult.
Instead, I now get a load of hokum about missing dependency files - looks like BIOS roms. C'mon, LB, if you say you support a system in a drop-down box, I don't expect to see complaints about missing firmware roms afterwards. Not even a hint as to where to get these roms, either.
"Launchbox" - it's in the name, right?
Anyhow, I've requested a chargeback on my credit-card, and warned a few forums not to touch this garbage with a cattle-prod.
Happy gaming!
