Any ND-6100A firmware hacks?

What about the ND-6100a. Can anything be done with this?

The only thing I know of for the 6100A is an RPC1 firmware by TDB.

What firmware version is on your drive?

The ND-6100A can now be hacked to a ND-6500A to add 8X DVD-R and 4X DVD-RW.

Tried it on the NEC ND-6100A that came with a Dell Inspiron 8600. Works great so far.
