Great Work, pegahic!
I will take a look at the dump when I arrive home today. Try to build something from it

EDIT: Do you think it's a good idea to creat a topic at DryOs Development?
Well, I'm here taking a look at IDA and I hope to get something working today

Will keep my progress posted.

So, this is my status for the day. I'm looking at a470 for reference, and I could almost finish boot.c. However, when I tried to compile a test, it misses some functions, and also, when putting nullsub to this missing functions, it gives lots of errors of linking, like "undefined reference to `malloc`", which had his name detected by sigfinder.
I will stop for today.
