Here is an experimental one :
http://www.tepetaklak.com/data/yal-wconfig.rar
Dol has a config string in it,
default title id is : RCPP18
default config is : CFGYAL00P
just search for them in the dol with an hex editor...
config chars are
First six characters (CFGYAL) : Just magic
7th char. (0) : if 1 prints progress, otherwise doesn't print anything on screen...
8th char. (0) : Force region, if set to 1 then next char is the forced region...
9th char. (P) : Forced region
So if you are using a ntsc game on a pal wii you should make the last two chars. of the config string 1E
Also fixed the date bug...
ps: I'll release the modified sources when I get something automatic for wad creation for all the stuff...
