Use the "Unlimited Sapphire Koins" trick, then press R2 on controllers one and two to display the wager screen. It should be on Onyx Koins. Change the type of Koin to Sapphire, and a large negative number should appear. Then, change the type to the Koin of your choice and press X on controllers one and two. Press R2 on controllers one and two, and you should see the same number of 1000000 for the Koin you just set the wager for. Change the type of Koin being wagered to either of the ones that say 1000000 and a negative number should appear again.Cchange the type of Koin to another that you want to have unlimited of. Then, repeat for all the Koins so that they all say 1000000 and make a wager of negative Koins. Do a fight, have either player win, and both profiles will have unlimited Koins.
