CodeBreaker support F and 9 master codes but if you play with for example OPL or HDLoader,at least here,master codes that start with F are not working so I have to make a master code with 9.
Download
this program and run it.
Enable the "Master Code" checkbox,click on the Search ELF button and select the main game executable(S***_***.**)
You'll see bunch of lines...for example from MNJ
Take the address part as address(and change the first digit to 9)and take the Curr Op as value and then try this master code.
If it doesn't work,try so other
Also CB also support RAW codes so you don't have to convert them to v1+ or v7 common.
And one last thing(maybe you know but I'll say it anyway).When adding codes to codebreaker,every singe code for the game must be the same time...for example,if you have RAW codes,the all of the other codes(including the master code)must also be raw(the same apply to v1+ and v7 encryption)
