VTI does dissasembly quite nicely. However, accomplishing what I think
you're talking about wouldn't be as simple as just placing a 'jp' where the
reset all memory routine is in memory since such memory is generally write
protected (read: ROM). If you want to make it seem as if the memory has
been cleared when it really hasn't, your best bet would be to write an app
hook to handle it.
