I used an 8gb microsdhc card with SD caddy, already formatted to Wii, renamed private folder, unzipped lerterbomb private folder and boot.elf to card, it worked just fine, clicked the bomb, got into menu, kids flopping all over me, accidentally hit exit in menu instead of installing, got black screen, waited a long time then turned Wii off then on, no more bomb letter, can't find it on any dby gnomos - Getting Started
