Ok Buddy my fault lol
I just recently edit the thread so it may be confusing right. Will there is two way :
So about rga right.. so for that
1. Rga is only applicable for compressed ver , I mean you have changed the compressed file extension which is zip to rga then only it will work correctly
2. You can use uncompressed ver as there is not need to change anything, download, extract, use . As simple as it is
