okay, i saved this about .. three years ago, from  a Taiwanese auction site, and just recently found it again:
%20Finae%20Fight%203%20Super%2025%20in%201.jpg]http://fuji.drillspirits.net/stuff/[SC-128]%20Finae%20Fight%203%20Super%2025%20in%201.jpg
its a 25 in 1 multicart, ID no SC-128, with JY/Hummer's Final (well, "Finae") Fight 3 on it, which as far as I know was never included on a JY multi. the famous 45 in 1 with the full version of SMW, JY-120, was AFAIK also released as SC-120 as well.

now all the known JY multis after 120 have very standard, plain looking menus compared to the earlier ones, and are full of all kinds of cheap hacks and other companies' originals that you wouldn't usually find on an "old" JY cart, with way fewer actual JY originals.

so i'm wondering if there was some kind of split around the 45-in-1's release, where the "real" JY company staff became "SC", and whoever was left at JY just carried on cranking out shitty carts?
