After a little investigation and after comparing a few already hacked .bin files with their originals, I decided to bring out “my own” firmware to the market here, hehe
I chose the TDK firmware 1.34, because according to this thread it has the highest writing strategy version numbers at the moment. As I’m not able to speedhack media, this must be enough…
Here are the changes to the original TDK firmware:
- Name string changed to _NEC DVD_RW ND-2500A
- Riplock removed
- Region protection removed
Note: This firmware does NOT support bitsetting and can NOT burn dual layer discs!
It should work on every ND-2xx0A (and their OEMs). You have to flash it in DOS using this tool from the Dangerous Brothers.
I got some pretty good results especially for my +RW discs (PHILIPS 041, RICOHJPN W11). I also burned one +R 8x (RICOHJPN R02) and got a very good burn (as good as RICOHJPN R02 can burn). Too bad I can’t perform error scans, as I don’t own hardware for this. Only thing are some reading curves. I attach the RICOHJPN R02 curve at the end. Perhaps some of you can try burning with this firmware and post the results?
