hey cool, thanks for the dumps! I always wondered if some of these GBA multicarts might have something interesting on them, and it looks like the 290 in 1 does - "Hua Rong Road" AFAIK isn't dumped separately (or is it?) ... I wonder where they got it from?
I also find it kinda interesting that that one uses "classic" multicart names for some of the games, like Saiyuki World as "New Son Son" and Obake no Q Tarou as "King of Ghost".
