Sorry if this old news, but I just found a thread explaining how to install and run AKAIO on an R4Ultra. Using this method, they were able to play M&L3. Maybe it would be possible to get AKAIO running from other R4 models? Just throwing it out there for what it's worth.
Original thread:
1. Download the AKAIO 1.4.1 Proper and R4 Ultra Kernel 1.54 from here : Sorry guys, gonna have to find it yourself!
2. Delete all the files of your old firmware on your micro sd
3. Copy all the files from AKAIO 1.4.1 Proper and R4 Ultra Kernel 1.54 folder you just download into your micro sd (yes, you mix those two firmwares on your sd)
4. Copy the Mario and Luigi game into your sd (the patched one with xpa-mal3.bat, not the clean one)
5. Insert your micro sd into your ds then turn on your ds
6. the R4 menu will show up but instead choosing your rom, you choose "AKMENU4.NDS"
7. Now the AKAIO menu will appear, then choose your M&L game from there.
8. Play the game
Using this method I can play the game perfectly.
With this method you can also play Kingdom Hearts 358/2 days.
So you can play both K.H 358/2 and M&L B.I on r4ultra using this firmware
