While it's possible to run the game in fullscreen mode on the Wii using SDL1.2, it doesn't work this way using SDL2. One would have to switch screen resolution 320x240 to 640x480 to make it look like fullscreen mode but then the game would run really slow...
I have been working on BLOOD for the Wii for a few weeks but that was 2 years ago until I noticed that it would randomly crash out of a sudden at some point and I never managed to find the origin of the bug.
@nitr8, If you consider open-sourcing this, then I'm sure somebody could point out the bugs for you in the repository, such as walking through step-by-step on what it's doing.
I have 2 USB Gecko's. I'm using one for debug printout messages while I use the second one for realtime debugging within Eclipse where I make changes to the code
