FreeMCBoot is a great and probably the only option for PS2 games. If you have a PS2 Phat, a memory card, network/HDD adapter, a spare HDD laying around, then all you need is the ability to burn a single layer DVD, a small USB flash drive, and away you go. I had it running for years before the HDD took a dive. Was a bit of a challenge to get it running again. For PS1 games on a PS2, it is a challenge and you have to use an emulator or mod chip,. But that is why you use a PS1 for PS1 games and the ODE's available are the best option for PS1 games.Great to hear!
I still use DVDs with my PS2, but have been thinking about a better solution. Did you research the options to run PS2 games from HDD or SD-card? Is FreeMCBoot the best option out there, or are there also alternatives?
I had some challenges getting the other programs like OPL (Open PS2 Loader) to copy to the memory card, but I found a previous release of FMCB that finally worked. The other challenge is the network/hard drive adapter. The Chinese SATA adapters seem to work only some times. The one I picked up didn't work. Kind of a dice roll if you pick one up. But I have a legit Sony network/HDD adapater and an ATA HDD laying around and that works for sure. I bought the SATA upgrade for it which will be here in a few days and will be using an SSD shortly. I don't want to lose my HDD again.
There is no reason why you shouldn't run FMCB if you have a PS2 Phat. R-Type Final and Gradius V alone are worth the effort and expense to experience on a cab. FMCB is a soft mod. There is no dissection/modificiation of your PS2 needed. The PS2's library is expansive. You'll actually be preserving your PS2 running FMCB as you won't wear down the laser on the DVD drive.
