I received a private question about "Shin Mahjong Super Battle," yeah, it does not say MindRec, but it was something that I did.
The story ... back when the internet was still young, and people made it their business to steal information and sell it as their own, I noticed that much of the data in the PCECP and PCE Complete Listings was being pilfered and distributed without proper credit. So I eventually started adding some fake information just to see how far it would go. So "Mahjong Shin Super Battle" was created. A completely fake game, complete with fake cheats. At some point I noticed that the fame game had spread far and wide, and that ROM site folks were asking for this mystery game. So the plan was to release a game with only the title screen, but then crashed beyond that. So what you see in the video is basically that ROM that was created, It was never released. But if you search for "Mahjong Shin Super Battle," you will still find quite a few sites that list the game and cheats for it.
I released a video of MSSB a while back, along with the full explanation, and the number of sites listing it have been dropping. But even Digital Press has the game listed (or did).
