WR and Pikachu were originally made to be used with 2nd-boot, but that never worked with the Bravo. I've never tried them on multiboot. I don't normally use multi boot due to too much music on my sdcard. That, and I had problems with roms with bugs/glitches they didn't have when installed to the system.
Honestly, WR is buggy as hell. I'd release an update, but I can't get some of the tweaks to work right and there's no radio after installing the updated one. If you want an updated WR, the closest thing is my current nandroid...The only problem is its touch recovery and I've never once tried multi boot with touch recovery.
I suppose I could remove touch recovery up my nandroid later today. It has working Bravia(yes I tested before and after and I made a difference), updated beats audio, 30 step volume, cyanbread framework themeing, brews coffee, the miui explorer from Defy forum, custom framework animations, transparent status bar/notification drawer, walks your dog, and zepplinrox's scripts already ran and set up. It has everything WR had except Go Launcher and Miui apps.
Autocorrect is pissing me off. Miui was Louis, Mohican, and Minuit. And my thumb is sore now.
