So what was wrong with UMCD-R?
I hear stuff about how devs don't want this and such...

the author has seen his wonderful code being used for illegal purposes....
started with some trying to use it to burn games.... which failed... but this still offended the author and he has requested that this forum not post the code.... I'm pretty sure that Mr. Winchester would feel the same about kids shooting each other these days...

That is not the only reason.
There is also the fact that the company Datel stole the UMCDR code and incorporated it into their own product, the "Action Replay Max" series. AFAIK they did this without even asking for his consent, never mind bothering about what his answer might have been... So it is not at all strange that he does not want other people in the 'scene' to help Datel make good money from this theft.
Had it not been for this theft, I don't think the author would have demanded that future UMCDR support be dropped from homebrew programs. The other 'illegal' usage you mention was of very minor importance, partly because it didn't work well, but mainly because very few attempted to use it that way. The author of a general purpose homebrew tool or driver (like UMCDR was intended to be) has no responsibility for its potential abuse by other persons (such abuse is possible with almost any tools).

oh yeah... i forgot about that... and I have an AR MAX... never use it for that though... takes too long to make a disc that may or may not work.... use 'me' HDD for 'dat'.
plus this action of denying use also helps shield him from Sony's long arm.... in case it ends up being used too defeat Sony's protections....

How was it released? Was it a public licence? The trick of using audio cds to bypass playstation protection has been around a long time; the old Action Replay for PSX uses it I believe. In addition, the program Datel has, called the AR Max Media Creator, does output to UMCDR, but it seems to not be compatible with Joliet naming (names can be over 8.3, but no spaces or punctuation), while UMCDR can -- try making a "umcdr" with MMC and then CDgenPS2, and load both in pgen or something umcdr compatible. Somehow they're different.
Even if Datel stole UMCDR, what's done is done. Why should the rest of the homebrew community suffer for what Datel has done? They're still making money off their product. Removing UMCDR from the internet only hurts THE COMMUNITY.

What you say merely illustrates my point.
For the 'Max Media Creator' Datel had to write the code themselves, and so they missed some of the capabilities inherent in the PS2 code.
However, our opinions on this don't really matter.
For the ps2dev drivers the author himself has the final word.

I see your point, but the author has made his decision on this.
However, as you may have noticed there is a new format available that can be used as a replacement for UMCDR (also accepted by non-mod PS2s). This is the CDDAFS format introduced with the SMS media player, accompanied with a very nice PC program (CDXplorer.exe) for making CD images for that new format. Hopefully emulators and other homebrews that need CD access will add support for this format ASAP. (I'm certainly thinking of doing this for LaunchELF.)

which would be the same thing... a reverse engineering of the same old code.... UMCDR is an audio CD format right.... so is CDDAFS... and the MMC format from Datel... would this new format also offfend the original creator.... and thus should not be allowed on this forum....
I personally welcome it... and haven't seen it yet... mostly because SMS doesn't support the HDD yet so I haven't been too interested.... but this might be worth my while at the moment.... to test the Divx codec and it proficiency.... I'll have to check it out...

No, you are wrong on this. No reverse engineering is involved here. Neither for the original UMCDR design, nor for the new CDDAFS design. They are both original creations based independently on the same idea.

Not really. They are both formats designed to store digital files, but to do it using storage methods that conform with the usage of audio tracks on audio CDs. Note that the two formats are NOT identical, or even compatible, though both serve the same basic purpose.

and the MMC format from Datel...

That is a direct rip-off of the UMCDR format.

No. The SMS project, which introduces the CDDAFS format, has been adopted into the CVS repository at ps2dev.org, which is also where you can normally find the creator of UMCDR. AFAIK he is not in any way opposed to the new format.

It's definitely worth testing, though SMS itself still suffers from the lack of a good user interface.

belive what dlanor says... in the umcdr irx file (which they renamed to .MOD or something stupid), search for the string Drak and you will see how they blatantly stole his code.

its a bit longer of a twist and turn than just datel stealing the code. Yes they did just steal it however there is someone else involved in this. At the time sjeep was contacted by datel to inclue pgen in the new AR Max. However, they had no way of users adding their own roms. Sjeep did tell datel to contact drakonite in order to use UMCDR, which was already compatible with pgen. After just some short talks datel reps suddenly stopped corresponding via email. Months later the action replay max was released along with the UMCDR code inside.
We can only clearly see that sjeep knew about the UMCDR source theft way before datel released the AR MAX Evo while working for them. Once the truth was exposed Sjeep also went on the record to defend datel and stated no umcdr code is inside of the armax. He claimed datel had the capability to do this a long time ago. Anyone with a hex editor can see this wasnt the case.
Here is the post that sjeep used to defend datel
http://www.gamebase.ca/gamebase/inde...38467#msg38467
Keep in mind UMCDR is a two fold piece of code. One being the cdroms format and the other is the code that will read that special format. This code must be implanted inside of the ELF itself. So sjeep must have known one way or another and must have had some involvement in this umcdr contraversy.
Also near this time hermes released CDX, a variant of UMCDR just as drakonite was pulling UMCDR out of the scene. Hermes first admitted it was a variant of UMCDR with some improvements. Once UMCDR was pulled his story changed, claiming it had nothing to do with UMCDR and that he would not remove it from his projects. His variation of UMCDR also appeared in the O2 modchip and some of his other projects he releases under his new name "Mr.X"
We can all safetly say that the format has been pretty badly abused by others. You can see why drakonite doesnt want it to be used anymore.

Sjeep told a half truth.
It is true that Datel did a similar trick earlier, and yes, it was for the burnable upgrade discs for the old AR/Gameshark for ps1. That much was true.
HOWEVER, even though they could have rolled their own, they stole Draks so they could rush out pgen without needing to write their own CDVD.IRX replacement. and since they needed UMCDR for pgen to load it's roms, they went ahead and stole it for use in the rest of their product as well to save a few bucks.
CDX is a ripoff of UMCDR as well, and IS the reason it was pulled in the first place. That was the warez attempt. Datels theft really pissed him off more, though.
Datel has in fact admitted to using UMCDR. They haven't outright said so, but calling one partiuclar elf a "UMCDR Updater Software" is pretty damning evidence.

This page on their servers offically makes sjeep a liar. It's also why, if I had the knowhow I'd crack toxicOS. No copyrights for those who do not respect copyrights.

as I recall the new format was designed specificaly for media files, and not data, but it may be possible to suport this new format in elf launchers.

so someone wrote UMCDR code, let the world see it, and is now pissed that some company is selling a product that uses it?
what kind of license did the code have?

the UMCDR code was nEver released. just a replacement for cdvd.irx that supported the new format, and a program called padISO that transformed a normal ISO into a UMCDR. neither is legally downloadable anymore without speciifically asking Drakonite himself.
