Hacking cios36rev8 and cios37?

[unr007d]

last night my wii stopped playing my backups (getting dvd read error 349) which is bad media or cios not properly installed... I know it's not the media so it's gotta be the cios..why or how could it corrupted? I have deleted ios249 with anytd and have installed cios37 as ios36 dip7 on 249 with mrkinators multi-installer (which what I had before so my rockband instruments worked) and now i'm still getting that 349 error...so I am going to start over with the ios16-prod.wad and isodowngrader etc... as I have read should fix it....but I was wondering if I could install cios36rev8 on 249 and install the ios37 as 36 on 248 and still have my rockband instruments work and get the benefits of both cios? I am using djtaz's autoboot gamma channel loader with the 002fix if that makes a difference with my questions..thanks
