Best firmware for 851s and ricohjpnr01

Hi…i’m a pretty owner of liteon 851 and i use gsc2 firmw to write good dvd-r discs(ritekg04 and sony2x)
Now i have ricohjpnr01 dvd+r discs and i want to know, in your opinion, the best firmw to write ricoh disks to 4x and 8x speed.
With gsc2 firmw 8x write isn’t good…there is at the middle of disc a blank(not writed) part.




I have an 851s @ 832S with CodeKing’s CG3B firmware and my 851 is awesome with this firmware. But some 851s like it and it seems that some do not. You can always flash back as well . I also used USON on my 851 too and got good results but CG3B is the best IMHO.

Take a look at this post with 851s@832S with CG3B firmware.


For me - it is GS0K. See this post and my scans (on the bottom of the page):

OK tnks v m boys…so i must try both firmw…but first i change to gs0k firmw.
Dwrbudr, what about 8x speed? do you use gs0k firmw modified with omnipatcher? What changes do you made?



Those are REALLY nice scans as well!.


I didn’t make any changes on the firmware except to increase the reading speed from 6x ot 8x with OmniPatcher.

Here is a scan from a burn made an hour ago:

Good media + Good firmware aaand + Good Drive = Good Burn :iagree:

Q: Best firmware for a 851S drive and Ricoh R01?
A: ANY firmware

Quite frankly, I’ve had good Ricoh R01 burns ever since… a long time ago. The Ricoh R01 burns that I get with the old GS0F and the new VS0B are pretty much identical.

I’m not sure where to put this but, I’ve got a couple of memorex Ricoh scans of the same disk with the 851s as a reader and the Nec2500 stock fw1.06. The original scan was done on fwGs0a, and the new scan with fwGS0k. Why is there such a great improvement. Most of my scans for the memorex ricoh media is similar to the first scan up to and includeing fwgs0h, I’ve never had any better until the update to fwGS0k.

Did my 851s suddenly become a better reader with this fw or is it just ignoring more errors? Has anyone seen this?

tanks code but i don’t know the best firmw for 8x write with ricoh r01.
With gsc2 firmw 8x write isn’t good…there is at the middle of disc a blank(not writed) part.


I’ve always burned my Ricoh R01 at 8x, starting with GS0F, on up to VS0B. :slight_smile:

Sounds like a shifting problem. Make sure that force-shift is off and that early-shift is off. Also, there are some people who report better results with the older-generation firmwares (i.e., GS0F), and some who report better results with the newer-generation (i.e., GS0K, GSC2/US0N, VS0B). If the newer-generation isn’t working too well, give GS0F a shot and see if it helps.

tnk v much code…i’ll try with gs0k and your settings…ok bye!
