So this means you will be playing CD-Rom2 games instead of HuCards only? Lol, I remember you telling me you were interested in HuCard games only and me being confused as to why.
Well I've always had a duo, and have a ton of CD-ROM2 games. I just said that out of the few games that are available in both formats, I prefer to have the Hucard version. I kinda dislike optical media in general due to how fragile it is, but it's necessary if you want to play some of the best games on the PC Engine. I know my Hucards will probably still work in 50 years, but I worry about my CDs.
Everyone has lost a CD at one time or another due to a random scratch. Even without scratches, longevity is not assured. Case in point: I have two copies of Cosmic Fantasy 1, and both have laser rot. It's rare on CDs, but does happen. Not to mention the actual CD drives themselves.... Anyway, there's no sense worrying about it.
