Hi dvd_freak2005,
I just read your PM with questions, but instead of PMing you back I respond in this thread, since I want to make this info available to everyone with questions about the Liggy and Dee firmwares.
The firmwares in the "orig" column are the firmwares as released by their creator(s). Al of these firmwares have two features. One is called riplock, which slows down the reading/ripping of video DVD's and makes the drive less noisy during playback. The second feature is something called a region protection control, which means that a drive with this firmware will only play DVD's that are for sale in your region (i.e., when you live in europe, you can only play european DVDs).
(Note that "orig" here doesn't mean "official" as in "an official release by NEC". Only the "original NEC" firmware's are official NEC releases.)
The riplock feature is also present in some versions of unoffical firmwares, since some people want to keep the quiet playback when using an unofficial firmware; these firmwares are located in the "slow" column. These firmwares are all regionfree (which, what makes things a bit confusing, is called "RPC1").
Then there are firmwares which have the riplock function disabled, these can be found in the "fast" column. These firmwares are all not regionfree.
And then, finally, there is the "RPC1" column. The firmwares in this column all have the riplock disabled and are all regionfree (which, as said earlier, is called "RPC1").
Why are these firmwares available in so many "flavours" has to do with how they are modified by the firmwarehackers.
When an official firmware ("orig") is released by NEC, the first thing that (often) will be patched first is the riplock, making it a "fast" firmware. After that, the RPC will be patched, making the firmware an "RPC1" firmware. Hence, the entries in the "orig", "fast" and "RPC1" columns.
When Liggy adds a bitsetting code to a NEC firmware, the patching takes place in the same order: the original firmware with bitsetting capabilities will be released, then a "fast" version will be made, and after that a "RPC1" version will be made.
However, when Dee makes a x.Wx firmware, the process is different, because she always starts off with one of Liggy's RPC1-firmwares and then adds her code to this firmware. After that, she will release a version which has the riplock re-enabled; a "slow" version of the firmware (which still is an RPC1 firmware). Hence entries in the "RPC1" and the "slow" columns.
I hope this answers your questions.
PS I hope it is clear that "fast" and "slow" have nothing to do with the speed at which these firmwares burn DVDs.
