Hey guys, thanks to all of you (espcially DS1,CrashmanX, and Xist) in my last thread. Luckily, two of my friends are selling their silver dextar pack psp. However, they've both never hacked it (I'm getting either one for 50 bucks everything included beside games xD) and they are not aware of what firmware it's at (they may have updated as the years passed by). I don't know if this is a major concern and if this one measily firmware makes a huge difference I'll be really pissed :@. I'm positive that they have the hackable motherboard as they got it over 3 years ago which is when I believe it came out? Btw, I've search in both GBATemp and Google if the firmware mattered but no answer, only "Make sure the psp has this blablabla firmware and mobo." Well, if I can't buy from them I'll get one from Gamestop this weekend hopefully. Although I was wondering, there are two I believe CFW? Which one do you guys think its the most STABLE and "comfortable" (lots of features and etc) CFW? Finally, I've read that CSO and CSO+ are smaller size games compared to ISO. I've read half and half that some people have problems with both CSO and CSO+ and others say it works fine. The people that complained were having issues such as slow downs/lagg from time to time, errors, crashes, and screws up the CFW? So I want your thoughts on it guys xD. I mean smaller size would be a money saver and not a lot of transferring from PC to PSP for games. Thanks a bunch guys! P.S. Should there be anything I should check out before I buy the PSP from my friend? Like certain cracks (Example:old white DS) or buttons etc?
