--- Comment #6 from Vincent Povirk madewokherd@gmail.com --- Tried the instructions in comment 1, I get an error dialog:
0009:Call user32.MessageBoxW(00000000,00185dc0 L"Image file 'Z:\home\burn\Desktop\Dolphin\DBOOT.img7' is of unrecognised type '\6570\2f63\3176\6f0a'",00c0f830 L"Dolphin Smalltalk",00013010) ret=004015f1
That looks like ascii text misinterpreted as utf-16:
'\x70\x65\x63\x2f\x76\x31\x0a\x6f'
'pec/v1\no'
That's text from DBOOT.img7.
Is it possible this is pointing it to the wrong file?
