Read-Speed Patched Firmwares for LiteOn DVD-ROM Drives ====================================================== Patcher: Code65536 (http://codeguys.rpc1.org/) Release date: 1 July 2004 ### # Patched models: # LTD-163/XJ-HD163 (plus Dell's OEM LTD-163) LTD-163D/XJ-HD163D LTD-165H/XJ-HD165H LTD-166S/XJ-HD166S (plus Sony's OEM DDU1612) SOHD-167T (plus Sony's OEM DDU1613) ### # Disclaimer: # We are in no way associated with LiteOn, and this patched firmware is in no way associated with or supported by LiteOn. Loading this patched firmware will technically void your warranty! We take NO RESPONSIBILITY for anything that may result from the use or misuse of this patched firmware. USE AT YOUR OWN RISK! ### # What has been patched? # 1/ +R and -R reading speeds 2/ +RW and -RW reading speeds 3/ DVD9 (dual-layer) reading speeds 4/ +R DL (recordable double-layer) reading speeds (only for the SOHD-167T) Note that for most users who do not burn DVDs and who do not rip dual-layer DVDs, these patched firmwares will do nothing for you! LiteOn DVD-ROM drives do NOT have any movie-industry-inspired video rip-locks in place, so a pressed single-layer disc can be ripped at the full 16x using just an official firmware! The patched firmwares are intended for people who have recordable and rewritable discs in their collection and for people who would like to slightly increase their dual-layer ripping speeds. ### # What has changed since the patched firmwares released earlier by The Code Guys # and by The Dangerous Brothers? # 1/ RW reading speeds were never properly patched in any of the original patched firmwares. This oversight has now been corrected. 2/ There is now the option to use a patched firmware with DVD9 (dual-layer) speeds patched. DVD9 speeds were not initially patched because there were some reports of reading problems at higher speeds. However, these results do vary, so instead of deciding for the end-user, We have decided to let the end-user decide for him/herself, and thus, there is now the option to bump DVD9 reading speeds to 10x, up from 8x. 3/ The older patched firmwares patched a byte that did not need to be patched. This byte is no longer is patched. This patched byte also seems to have been the cause of the SMART-X problems (noisy movie playback) problems reported with the original patched firmwares. ### # Installation: # 1/ First, select the patched firmware that is right for you. The names of the firmwares should be self-explanatory. If, after loading a firmware, you find that the speed of that particular firmware was not suitable for you (too fast or too slow), you can load another one. 2/ If your drive IS NOT a 163/163D, simply double-click on the firmware of your choice, SELECT THE CORRECT DRIVE, and initiate the flash. 3/ If your drive IS a 163/163D, you will need to use MtkFlash to load the patched firmware into your drive. You can find MtkFlash at the following location: http://dhc014.rpc1.org/howto.htm#mtkflash 4/ If you decide to change your mind, you can easily "uninstall" all of these patches by simply loading a stock (unmodified) firmware into your drive. There is a copy of the stock firmware included in the package. ### # How do I make my drive region-free? # 1/ If your drive IS NOT a 163/163D, you should consult this link: http://dhc014.rpc1.org/LtnRPC/ 2/ If your drive IS a 163/163D, you should consult this link: http://digi.rpc1.org/rpc.htm ### # Notes: # 1/ Except for the name, the XJ-HD drives should be the same as the LTD- drives. Their firmwares are interchangeable. 2/ For the OEM drives (listed in the patched drives list above), you can use the corresponding LiteOn firmware (e.g., the firmware for the SOHD-167T if you have the DDU1613) instead of the OEM firmware if you so desire. Since LiteOn usually does a better job of maintaining its own firmwares than it does maintaining its OEM firmwares, this is something that might be worth trying. 3/ Discs booktyped to -ROM should not be affected by these patched firmwares and should read at the same speeds as normal pressed discs. So, for example, if you loaded a firmware for 14x +/-R into your drive and then your drive read a +R disc with a -ROM booktype at 16x, this would be the reason for that. However, there have been reports of some booktyped discs that get treated like a normal recordable disc instead of a booktyped disc (thus subject to the effects of the patched firmware). This may be the result of problems (incompleteness?) with the booktyping process, as this phenomenon have been reported with other readers/players produced by other manufacturers. 4/ If you're wondering, no, I did NOT manually patched all of these firmwares. I wrote an auto-patcher that generated all of the files in the package. Just in case you were about to say "get a life!" ;-) ### # Acknowledgements: # 1/ The Dangerous Brothers, for making the original XJ-HD166S patched firmwares and for their wonderful knowledge-sharing. 2/ C0deKing, for everything that he's taught me about firmware patching. 3/ The folks at rpc1.org, for providing the webspace.
This patched firmware is based on the official CH12 firmware from LiteOn.
