Kind of an interesting cart, but seems to have been the victim of a manufacturing error (I assume?) with one of the ROM chips being wrong (probably from a different multicart in the same line), resulting in most of the menu entries starting up a completely different game or just not working at all.
The rest are repeats. It also doesn't reset before booting a mono game, resulting in a slightly odd but tolerable default palette.
The menu is quite a simple design often seen on GBC multis, with "SUPER 31 IN 1" multicoloured at the top and the games listed in That One Classic Videogame Font.
PCB is marked "880503C" with a date sticker indicating November 2000.
(there's also a battery with a soldered-on clip marked 98-03 - if that is the expiration date rather than the manufacturing date, the battery would have been 2 and a half years expired by the time they used it... unsurprisingly it is now dead)
