05/06/2019 - It is highly recommended to have a BIOS FREE chip on Naomi base for using the 4.02 firm of the dimm
3 months have passed since I began this project, and want to share to all the community this contribution. I have extracted the binary file inside an updated dimm to 4.02. The file I'm going to publish it's only useful by flashing it in a TSOP48 chip like M29W160EB-70N6E, and after that by being soldered to the dimm. You can have a direct updated dimm to 4.02 without any support net dimm.

I hope you enjoy this. Many thanks.
