Have you tested 271 yet? wondering if it fixed Fzero black screen and 4 led on the wii remote since 270. like you said we might have to find another copyIt looks like I'll have to find myself a different image. The copy I have works with 2.265 but not with 2.270, I'll keep u posted when I find a version that works. wondering if it's worth putting an MD5 of your copy, since it's multiple files I don't know how that would work.
To those whose copy of F-Zero AX stopped working with 2.270, see if u can find a different image and post your results. Make sure it's a different copy then the one u already have.
I have not had a chance to test 271 with my copy of Fzero AX yet.
