I'm still more curious about some of the stuff that was supposedly being offered in official packs.
Goal '92 was featured on a number of flyers / adverts.
It's a bootleg.
You can't license a bootleg, there is a mix of hacked code owned by the original manufacturer (from which they don't appear to have any other games licensed either..) and code written by the bootleggers, as well as stolen music / sound effects from another game entirely.
That's not something you can include in a commercial product, period, yet it was.
Furthermore, if you had an official license, you'd likely be supplied with information / resources to emulate the original game / hardware, including information on the protection devices (Seibu Cup Soccer still doesn't work in MAME for this reason) I actually see very little evidence that the guys doing their emulator software were capable of actually emulating anything from scratch (as in figuring out how things work) tho, so maybe even with original information they would have struggled. At worst it could have still been better disguised to look like the original tho, for example taking the bootleg patches to the protection and applying them to the original game.
I suspect there is still plenty more dirt to be dug when it comes to Ultracade, Foley and the whole saga.
