1) no R1 stands for release 1 as it was the first release of 0.9.2 which we later replaced.
2) what? i didnt understand what on earth you meant.

 

thnx, general question answered , second question closed too

 

I think he's asking about the beta versions that I list in my beta screenshots thread on GE ref. SunnyDrake: If you see a version like 486 R1, 486 refers to build number and R1 would mean revision 1, meaning that the build was slightly changed, but not enough to constitute a new build number (most likely because the change is either not permanent or is a very experimental change to the build version). One thing to note is that this question would have been better to ask on GE (since it pertains to a thread there and most users here won't know what you're asking, or how you would come across build numbers like that).

 

Thnx GP for answer this is just what i where thinking.. i get some free time, so i perform some analytics on pcsx2 project to add some news filling information blackhole
