The purpose here is to play burned PS1 discs like that Rockman 8 prototype, and to play my real copies of Rockman DASH, and Biohazard on my PlayStation 2 Slim SCPH-70001 and PSone consoles. I understand there are "creative" methods to accomplish this.
The most common ones I find on the internet are using a sort of double disc swapping method that involves a real PS1 disc and a burned/imported one, and you have to repeatedly swap them both in a timed, instant fashion. Which I have tried doing that with just my PSone console many, many times to no luck. I find it to be complicated and stupid, and I'm sick of trying that.
Another is actually opening up your console (PS2 or PSone), and soldiering mod-chips into the console. I'm willing to do that with just my PSone console, but I ain't tampering with my PS2 Slim. It looks complicated, but it does sound fun to experiment, though.
Finally, and possibly the most costly, is buying one of those Breaker Pro discs for $20 USD which "allows playing PS-One import games and backup games on PS-One and PS2 game console without any internal modification". Sounds exactly what I want. With it, you only have to swap a disc once and not have to rush, unlike the first method mention above. I don't know if it scam, though. It does sound too good to be true.
I also have Action Replay for PS1, and Action Replay MAX for PS2. Could I use those?
Do you recommend that I invest on a Breaker Pro disc, or is there some other unlisted method that I haven't touched upon or don't know about?
