Multiboot DS roms on flash cart? NDS and GBA at the same time? Warioware won't work?

Ok, heres the deal. I used wifi to replace my firmware, and I used the NDSPatch to load games onto my 512 x-rom cartridge. Everything is working great. So far I have gotten metroid, castlevania, and a couple other games to play just fine. I have 3 questions though.

1) Warioware Touch won't play. I read it has something to do with "unlocking" it? Can anyone shed some light?

2) More importantly is there a working multiboot program for NDS roms?

3) Is there anyway I can use my x-rom cart for both NDS and GBA roms at the same time? It sucks have 1 NDS rom on there and I cant use the extra space for any GBA roms.

Thanks in advance
