@kokokool ... The rebirth series needs neek2o installed to work, along with some other WiiWare/N64 titles. Here are instructions on how to set neek2o up. Once installed, go into "Castlevania Rebirth" game settings and force neek2o. That should do the trick. I have a list of problem games that ill try to hunt down & post.

Using real nand you can install maybe 20 VC/WW games tops. The Wii's internal storage is very limited. With emunand you can install the entire VC/WW on USB/SD if you cared to. For me, I've created hundreds of injects (mostly mega genesis) then edit to show artwork & play through WFL emunand plugin. That is really the only advantage but it is a huge advantage. Below are instructions on how to setup neek2o on Wii for nearly 100% VC/WW compatibility.
Edit:
I missed an important step at the end. The neek2o_NK2O_1.wad must also be installed using either WiiFlow Lite or GX Wad Installer. You cannot exit neek games properly (hanging black screen, blinking blue) without it installed.
