i'm with you guys, i am determined to write my own main. i agree that if you can patch a main firmware then you should be able to write one. i mean if the manufacturer ,or whomever does it, can write a firmware that works regardless of what the checksum is when they create it; so can we? i am willing to waste away all my free time with this ... fall into disrepair, etc. etc. so on and so forth :D there has to be someone who knows how 'they' compile the main files, and therefore how to decompile/recompile them. any takers?
