You CAN use codes with Swap Magic!!
 

For anyone using Swap Magic disc's and want to use cheat codes there is a way to do it now. You need to use the Spanish CD Boot Loader to do it. It IS an extra swap but worth it if you want to use codes. I tried to attach it but can't. I did NOT create it but it does work. Either PM me if you want it sent to you or just go to www.ps2ownz.com and download it there. :)
