Well, the problem started when I had the stock b2.11 kernel. I installed Hijack, and this didn't help. I wanted to see what was going on, so I installed the developer version of b2.11, and this didn't solve the problem. It did, however, give me a little insight into the problem. It didn't appear to be the HDD itself, as the HDD was detected without any problems. Whew! It revealed that it was a memory error of some kind. It was suggested that I load up the most recent 'stable' version, so I loaded up the developer version of 1.03. Unfortunately, this didn't solve the problem either. I have a custom boot logo, but I've tried using various 'safe' ones and they didn't help the problem. The animation is stock.
I can't seem to get to a shell, as the player crashes before the prompt for the shell access. I can, however, get to the 'pump' screen and to the memory check (this turned out normal).
That's about all I know of this problem, in a nutshell at least. I don't know where the config.ini file gets loaded, so honestly I don't know if it could be a problem. Either way, I don't really have a good way to get to it!
