It's getting hard to wait for when M33 is going to come out with CFW ver.6 (or at least version 5.50 which was mentioned that they have no intention of making).  With games like Motorstorm Arctic Edge and Disgaea 2 out on the PSP, the wait becomes more unbearable.  Maybe I should consider applying CFW GEN 5.50 instead?  A lot of forums say that we should wait for Dark Alex but does anyone really know what happened to him or is he ever going back to the PSP homebrew scene?  Feel free to enlighten me: how bad can it be to upgrade to CFW GEN 5.50?  Should I upgrade or wait for DA's much awaited version 6?
