We're up for some good ROMs today. There's nothing particularly new, they are just rare so it's good to cross them off of some of those unexisting list.

Starting up with the multicarts. As you've guessed, they're from J.Y. Quite original and unexpected coming from here, right? But hold your horses, there's one from Bit Corporation too!

31-in-1 (3150) (Bit Corp.)

This is, I believe, the multicart with the largest selection of games on which you had to move actual DIP switches to select your game. If you did the maths already (or just looked at the above photo…), you've noticed that there are indeed five switches sticking out on the front.
I'm not making a mosaic of all the games, especially considering that 31 is a prime number. A scan will have to do.

1995 Super HiK 4-in-1 (JY-016)

Can you believe it? It's the first multicart in the J.Y. line to feature one Hummer game!

1995 Super HiK 4-in-1 (JY-017)

Almost the same, except Dragon Ball Z 2 replaces Mortal Kombat II. This one is slightly easier to find and seems to have been one of the most popular J.Y. It got three reprints; one in 1996, 1997 and 1998!

Super Mortal Kombat III 18-in-1 Series (JY-062)

A fairly unusual one from J.Y., it's got an high game count and it's from 1996. Sadly, more games goes with the fact that those are mostly NROM titles. It still includes Mortal Kombat III Turbo… which is kind of a miss because by 1996, Mortal Kombat II Special had been released. A different solder pad configuration allows the menu to change to a 80000000-in-1 (JY-067) version. Modifying 0100 to various values also enable two otherwise-hidden menus.

Super Aladdin III 18-in-1 Series (JY-064)

Made with the same philosophy as JY-062, except it features Aladdin… and BB Car with an updated copyright line, explicitely reading in latin alphabet "Xinwei Huang". Weird.
A different solder pad configuration changes the menu to a 54-in-1, which is JY-065.

1996 Super HiK 3-in-1 (JY-070)

A typical J.Y. multicart. One Hummer game that goes along some late offocial games.

Rockman 7-in-1 (JY-208)

Now that's a weird one. It's first entry is Rocman X and that's actually fairly interesting! You don't see the later Sachen titles often on multicarts. Now you would assume the rest is the hexalogy? Well no, the second one is Rockboard and Rockman 5 is the Darkwing Duck hack. Oops. Rockman 2 ends up being the one missing (with the true Rockman 5). Those two likely ended up missing because of some ROM size constraint.

動動腦 II: 國中英文(一) (Dòngdòngnǎo II: Guózhōng Yīngwén (I), Middle School English)

As I said in the title, the cherry on the cake (?) is this Sachen title. The current dumps appears to be a mapper hack. So consider using that one rather?
