to get soul calibur 2 to work with HDLoader 

1 copy contents of soul calibur 2 except the system.cnf file to a folder on your pc 

2 copy cdloader files to same folder. the files you need are: 
system.cnf 
msystem.cnf 
scee_dd - this is a file folder 
fifademo - this is a file folder 
dummy.000 
cd7bet52.elf 

3 using the notepad, edit the system.cnf to say: 
BOOT2 = cdrom0:\CD7BET52.ELF;1 
VER = 1.00 
VMODE = PAL 

4 using the notepad, edit the msystem.cnf to say: 
\SOUL CALIBUR 2\cdrom0:\SLUS_206.43;1 

5 are you newbies still with me? your folder should now look like this: 
dummy.000 
slus_206.43 
bgm.afs 
movie.afs 
pad_0.dat 
pad_1.dat 
pad_2.dat 
cd7bet52.elf 
fifademo - this is a file folder 
irx - this is a file folder 
scee_dd - this is a file folder 
root.olk 
msystem.cnf 
system.cnf 
flistd.txt 

6 now i use hp record now to burn these to dvd, but whatever you use should work. 

7 now after you have your modified backup of sc2, just install it on your hdd using hdloader by whatever method is needed in your situation
