Since my Trainer Toolkit arrived last week, and Super Monkey Ball: Touch and Roll was in desperate need of more than just two codes, here's the start of hopefully several more. (Of course, the code is for Action Replay DS)
Press L to Jump:
94000130 FDFF0000
620E8AF4 00000000
B20E8AF4 00000000
D9000000 00000010
D4000000 00000280
D6000000 00000010
D2000000 00000000
The code is tested and working in both challenge and practice mode, and possibly some other unexpected places too. (I tried it in the Mini-Golf Mini-game and it was working there as well)
This code is also available on my subscription
