Avrin Posted September 15, 2009 Report Share Posted September 15, 2009 (edited) Just to sum the stuff up. With the latest hack (1811: 23, 1812: 7F, 1821: 97, 1822: 14) the RH10/910 may now be used to create legacy discs of any type (even the RH1 can't do that!). SP and MONO may be recorded on the unit, while LP2 and LP4 may be transferred from a PC (I recommend using Minidisc Simple Burner for that, so tracks can be transferred back using the RH1). Thanks for inspiration! Anyone to try the hack on an RH710? Edited September 15, 2009 by Avrin Quote Link to comment Share on other sites More sharing options...

Thanks for inspiration! Anyone to try the hack on an RH710? Just to put the record straight: the hack doesn't ENABLE the download of LP2 and LP4, that was always there... I just don't want to see anyone doing hacking to get a feature that is included. And the RH1 can, as you know, record in LP2,LP4, and SP - so it's MONO which is the interesting one. Did you go ahead and enable mono on the RH1? I got lost with all the back-and-forth to the point where your summary was very helpful. The problems with wrong headers that protect downloaded tracks should eventually (when linux-minidisc is completed) go away, because AFAIK it is merely a property of the headers on a NetMD disk. Well done, Avrin. (added) In the RH10 address 1111 stores 41 pairs of two-byte hex values, address 1112 stores 13 pairs of two-byte hex values, and address 1113 stores 27 pairs of two-byte hex values. Again, these are mostly zeroes, but some are set. Values specified in the service manual were not set in my unit (the respective pairs contained zeroes), setting them manually according to the manual changed nothing. In the RH1 each of these addresses stores 125 two-byte values, and most of them are actually programmed with non-zero values. Just idly wondering if HALF of the values are used for HiMD mode and the rest for NetMD/MD mode......... Quote Link to comment Share on other sites More sharing options...
Avrin Posted September 15, 2009 Report Share Posted September 15, 2009 (edited) Just to put the record straight: the hack doesn't ENABLE the download of LP2 and LP4, that was always there... Exactly. The hack only enables SP and MONO recording, but I mentioned LP2 and LP4 transfer just for the sake of completeness. Did you go ahead and enable mono on the RH1? No. Nothing new could be obtained from the RH1 by manipulating the above four addresses. Well done, Avrin. Thanks!

Avrin Posted September 16, 2009 Report Share Posted September 16, 2009 (edited) Just discovered another effect of using address 1821 to enable the MD REC Mode menu. Tracks and groups are now displayed "first-generation"-style when you scroll the jog wheel. Before that, when you moved the jog wheel one notch, it displayed tracks in the current group, and you could use the REW button to go to the group level, then use the jog wheel to select another group, and use the FF button to enter that group. Now the list is displayed exactly as it does on the NH600 - it contains all groups as folders, with the currently playing one expanded, and you can use only the jog wheel for navigation. The FF and REW buttons no longer have any effect in this mode. Edited September 23, 2009 by Avrin Quote Link to comment Share on other sites More sharing options...
Avrin Posted September 18, 2009 Report Share Posted September 18, 2009 Additional effect of the second byte at address 1811 (0113), common to all three generations of Hi-MD units (at least all those I have share this): Odd values (1, 3, 5, 7, 9, B, D, F) enable the Backlight menu (Auto/On/Off) on the remote. Even values (0, 2, 4, 6, 8, A, C, E) disable the Backlight menu. Quote Link to comment Share on other sites More sharing options...
eMDe Posted February 19, 2010 Report Share Posted February 19, 2010 Thanks Avrin, This thread is been a while, but I really appreciate your discoveries on the RH10. I love that device and the odd limitation of non-SP-Mode recoding was annoying me a lot. Cheers and keep us updated if something new occurs Lutz Quote Link to comment Share on other sites More sharing options...
efkeebler Posted March 6, 2011 Report Share Posted March 6, 2011 If someone would be kind enough to post the method for entering the service mode of the RH10, I'd very much appreciate it... the service manual for this model doesn't seem to spell it out, and I haven't had any luck finding it by searching this forum. Thanks very much! Quote Link to comment Share on other sites More sharing options...
sfbp Posted March 6, 2011 Report Share Posted March 6, 2011 Nearly all HiMD units are the same. Turn on HOLD switch. Press and hold some button (typically "group" or "menu", for RH10 is "menu") FF FF RW RW FF RW FF RW || || (10 key pushes in all). Don't forget to remove the battery and/or powersupply to get out of service mode. One more tip - with the lid closed you may well end up in key check mode unexpectedly. Simple solution... to get out of key check mode, open the lid. Quote Link to comment Share on other sites More sharing options...
efkeebler Posted March 7, 2011 Report Share Posted March 7, 2011 Thanks for the info - that worked perfectly! Quote Link to comment Share on other sites More sharing options...
sfbp Posted March 8, 2011 Report Share Posted March 8, 2011 Just consider all the ways we've now given you to trash your beautiful unit. Good luck! Quote Link to comment Share on other sites More sharing options...
efkeebler Posted March 8, 2011 Report Share Posted March 8, 2011 Heh heh, so true... but I was very careful in making the three setting changes to perform this SP hack, and everything works as expected, phew! Many thanks to those who researched these mods, as I personally find the ability to record in SP and MONO with this unit to be far more valuable than the ability to (muddily) play MP3s. I echo the warnings others have made about accessing service mode, having previously bricked a NetMD recorder by making a mistake in there (it was already dying, so no great loss). It's essential to read and understand the somewhat-confusing navigation instructions in the service manual before attempting to change any settings, and every last key-press should be made with great care!

TEKWRX Posted March 10, 2011 Report Share Posted March 10, 2011 Can somebody post a somewhat more specific tutorial on how to enable these hacks. I just got a M100 the other day, ($50 on craigslist ), and have no use for mp3, but SP recording would be very nice. I understand there are risks, and that's why I'd like a little more details so I don't mess anything up. I won't hold anyone liable Thanks Quote Link to comment Share on other sites More sharing options...
TEKWRX Posted March 15, 2011 Report Share Posted March 15, 2011 BUMP. I'll still looking to do this mod. Could anybody give some directions or post any links that spell it out? Thanks Quote Link to comment Share on other sites More sharing options...
TEKWRX Posted March 28, 2011 Report Share Posted March 28, 2011 OK, I figured out how to enable SP recording, it's working well. But I can only start the recording while the unit is off. I want it to work while unit is on. I guess I need to change value 1821, but I can't find it. Any help? Quote Link to comment Share on other sites More sharing options...
sfbp Posted March 28, 2011 Report Share Posted March 28, 2011 Hang in there. Quite straightforward, the best description is on page 14 of the NH900 service manual. I think they may have omitted this in some later models because a. they know we don't need to know it or b. we know already if foolish enough to want to tinker. Good Luck.

Got it working now. That info was in the RH10 service manual, but I guess I didn't read it clearly enough to adjust values. Quote Link to comment Share on other sites More sharing options...
