DC selfboot patch v3.0

[Megalexxx]

Try this :
_ BinHack your 1st_read.bin
_ open it with an hex editor (like Hedit)
_ look for "CD001"
_ note the number 4 bytes before (it should be 5C2E, for example : "5C 2E 00 00 01 00 00 00" + "CD001"
_ look for "A600000" (you should find it at least once, but you need to modify only one)
_ replace it by the code you noted before (5C2E...)

If you want 60 Hz, replace 090003610C711061 by 090003610C7130E1.

This should work.
