Anti-Mod Question - Already have modded PSX

[vandalous]

Hope someone here can help...

I've a modded 5501-series PSX. I just bought DDR 4th Mix and get the 888 screen of death when I play it. After some research, I know that I need to make a boot disc or make a copy of my game and patch it.

While digging around the megagames.com site, I saw that there are several bootdisc images, patching programs, etc. This is all confusing to me as I've never had to deal with a bootdisc before. I've seen the term "swap-trick" thrown around but I don't understand what to do.

Basically, I'm hoping that one of the experienced folks here can offer advice on what I should do to make my game work. I have a good-quality burner that is fully-supported by clone-cd, Nero, and CDRWIN. I also have all of those programs.

I'm not a N00B to computers or making backups, but I am new to the PSX world. Any help is appreciated.

Thanks!
