yeah, because it uses 249 by default. like said, there's no fake ios detection yet. you could do it manually, but you deleted the config file.
you could also do it in the meta.xml, but maybe the easiest is just to replace your slot 249 with a cIOS.
Get this d2x cIOS installer for Wii
create a folder in Sd:/apps/ called "d2x_installer"
extract the downloaded 7zip into that created folder
insert into wii
be sure you have a working internet connection on wii
launch hbc, launch d2x installer
select (with dPad) :
what : d2x v10 r52
where : 249
base : 56 (not the best, but you already have 57, let's not make an useless, duplicate, install)
version : 21010 or 65535 if you plan on playing disc from disc channel
press A to install.
when done, exit, and try your loader again.
note : by default, it will use slot249, which is base56 (not compatible with all games), so for better compatibility, do the changes from 249 to 250 anyway ! so your loader will use slot250 (with base57) and will work better.
ps: I'm leaving until tomorrow. I guess it'll work now, so it's fine. if you still have issues, you'll have to wait.
