Sure, take a read this article and all sub-articles according to earlier games of Accolade: https://segaretro.org/AccoladeArctic Circle System wrote: ↑13 Dec 2022 08:42As mentioned, weren't there some cases where certain games that started out as unlicensed titles were later licensed by the console manufacturer without creating a new ROM revision? How should that be handled? ~RedHiccup wrote: ↑01 Dec 2022 04:28Well the licensed flag has traditionally been used to mean "licensed by the platform holder". Anything that isn't licensed for IP usage would be marked as "pirate" I guess - there's a flag for that, used occasionally.

As an aside: unlike what I said before, maybe there is no need for a separate dat, as long as the homebrew/aftermarket stuff is filtered out by default from search results and from the default dat downloads.
Similar things happened between Electronic Arts and Sega before they became partners. The American company forced the Japanese to deal with them with great concessions. Otherwise, they wouldn't pay Sega any royalties on the cartridges they make and sell. This is well documented in the book "Console Wars" written by Black J. Harris in 2014.
