I said I didn't have the motivation for this one, but I lied. It was just too offensive to allow it to stand. It had to die a fiery death.
There were at least 7 instances where the developer name was seemingly made up out of thin air - ITL, Inter State, Now Production, Pixel, Sankindo, Sting, Tenky, Tomcat System, and West one. There' s no mention of these developers on the jewel case, the hucard, or even the title screen.
However, after some googling, I was able to link *a few* of them to the games in question. But it doesn't seem right to put some obscure name as the manufacturer.
So, as always - the standard here is the *name on the box/jewel case*.
Note that with this particular database, since it was such a mess to begin with, I went the extra mile and listed *multiple* names (e.g. Sega/NEC Avenue) for games where there were multiple names mentioned. I used http://www.pcengine.co.uk as a source, which is very accurate, and then checked that source with actual ebay photos if I could find them.
Game names were not changed. The only data that is a massive improvement here is the publisher/developer data.
I declare this the new official. May the old one never again see the light of day.
