Hi! I just recently found this multicart here and I gotta say, it's really awesome. Played this on my hacked Wii (using RetroArch because FCEU DX seems not working when loading this ROM) and it's very enjoyable.

Out of curiosity, how did you make a multicart menu like this? Please teach me how you did that because I'm working on a personal NES multicart project similar to yours and I really wanna make a multicart like this too.

Here's the standalone ROM of Jungle Book 2. I've accessed the DKC4 portion by hacking the game, but since this conversion is built for Jungle Book 2 in mind, the DKC4 portion have several graphical problems and I won't post it here for now.

As a bonus, I've also headered the "Unknown VT02-based 25-in-1" in MAME. The current ROM on FCpics is the exact same unheadered ROM in the MAME archive.

Looking through the GBA clone bootleg review, I found these multicards with a menu very similar to the PocketNES menu, although there were games with Gameboy Advance. I'm wondering how such multicards are created and if it's possible to create the same one.
