Walking Optimal Power Control firmware for LiteOn

The well known LiteOn firmware hackers CodeGuys have released an interesting unofficial firmware for the most recent LiteOn recorders. According to the release documentation, this version enables WOPC (Walking Optimum Power Control) recording for DVD+R media. The WOPC means constant monitoring of the recording process and immediate adjusting of write strategy on the fly.

This firmware has been design to improve the quality of burns when using +R media. It uses a WOPC (Walking Optimum Power Control) technique that adjusts the OPC at fixed points during the burn.

Versions marked with “sonyid” have the drive name changed to match that of the Sony DRU-700A and are not based on the Sony VYxx firmwares. Aside from the difference in the drive name, the “sonyid” versions are identical to the regular versions. These “sonyid” versions can be useful if you have locked OEM software that will work only if your drive bears the Sony name.

This firmware is not designed to allow you to overclock your media past the manufactures rating. In fact it requires you to use your media at the limits imposed by this firmware. Changing the write speeds of media in this firmware will seriously limit the firmwares capabilities to improve quality. However should you decide to overclock media anyway, this firmware will still perform better than the stock firmware.

This firmware has already been crossflash patched for 1673S users, has a faster LED flash rate when burning and has the following read speed changes:

+R/-R = 16x
ROM/9 = 12x
+/-R9 = 8x

No media burn speeds or strategy changes have been changed.
