LD Firmware Mini FAQ

Q: Which NEC firmware is this firmware based on?
A: This firmware is based on Liggy’s 3.07bt with version string changed, with riplock removed and RPC1

Q: How do i flash my drive with this firmware?
A: The firmware is now bundled with Liggys Binflash Unzip then run the package, now click on the FLASH button. The firmware will now be uploaded onto your drive, when completed you will be prompted to restart your PC.

To Flash a drive in DOS, LINUX or MAC. Use a current version of Binflash. Run Binflash with the commands necessary to load the firmware package. Binflash will accept either a .BIN or a .EXE file and flash your drive.

Q: What are the risks of flashing my drive with this firmware?
A: Great care has been taken to make sure your drive is not damaged in any way by using this firmware. However, you flash your drive with this firmware at your own risk. Neither I, Liggy, or cdfreaks will be held responsible if your drive or media is damaged in any way.

Q: Will flashing my drive with this firmware void my guarantee?
A: Yes, flashing your drive with any unofficial firmware will null your guarantee. If something should go wrong with your drive, you should buy a new one and not RMA the drive.

Q: Do I need special IDE drivers when running this firmware on my drive?
A Like all optical drives. It has been proven they work best when using Microsoft’s default IDE drivers. This is a must for this firmware.

Q: Why do i not get good results when i burn media on the modified media list at MAX speed?
A: This is largely down to the quality of your media. If the speedups don’t give you good results. Set the burn speed lower. This firmware will give good results at the stated stock firmware speed, without having to flash back to a stock firmware.

Q: What about media not on the modified media list?
A: All media both SL and DL not listed in the modified media table use the default NEC STOCK write strategies and speeds. If you don’t get the results you expect with media not in the modified list, this is a limitation of the media or drive, not this firmware.

Q: How do i set SL bitsetting for +R media?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.

Q: How do i use DL +R bitsetting?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.

Q: How do i use DVD+RW bitsetting?
A: Use CD Speed or WinBtype to set booktype to DVD-ROM This setting is remembered by the drive and only needs set once. Make sure no disc is in the drive.

Thank you!! :bow:


Fuji Film +r 8x Yuden 000 t02
burned at 8x

Those large spikes at the beginning make me wonder if its the burner, issue with media, or write strategy?


nice…i’ll be using this for sure
one question though…this is based on NEC’s 3.06, so for the media not listed on the modified page, does it use the write strategies from 3.06 or 2.U2??
because I have 3.06 currently, and don’t use any media listed on the modified media list until i run out of my current supply
i ask because i currently write yuden000t02’s, and it’s not listed as being modified. 2.U2 burned these fine…but might want to try with 3.06

Is it possible I miss the MCC004 in the burn speed overview? I hope its entry is ‘forgotten’?


The default strategy on this base firmware burned MCC004 so well, i left it till some results were posted. See here for my results
