Hey you guys, I'm fairly new to the PSP hacking scene. Just got my psp 2001 about 5 days ago. MHP3 is now out and, doing some research, I found out that I need to update my CFW to Gen-D3 Prometheus-4. Thing is that I'm now using 5.50 Gen-D2 and have read around that updating to D3 makes some games unplayable unless you apply a patch. Since I don't know the implications of this, should I update or not? I found some videos on youtube about how to do it, but I'm unsure. I'm playing CC:FFVII now, and alternating between some Tales Of games (Tales of Eternia, Tales of Mythology and Tales of Vs). Is the update reversable if it renders my games unplayable? Would it be worth to update this whole shit just to play MHP3? It's a good game, I spent a lot of time on Tri, too, but MHFU didn't quite please me. Thanks in advance. tl;dr - Is is safe to update from 5.50 Gen-D2 to 5.50 Gen-D3 and then to 5.50 Gen-D3 Prom-4? - Is it reversible? - Any info on games the update renders "unplayable without patches"? - Cost-benefit of the process?
