I was referring to your earlier assumption that the MECHACON would be different between releases in different regions, to facilitate CSS region-locking. And yes, I now think that it was also to prevent region-free playback via any method, as the Debugstation can actually run unapproved programs and is region free (even for Magicgate). It makes sense to make development hardware incapable of DVD video disc playback to avoid incurring the unnecessary costs of licensing, but that doesn't mean that DVD players had to be banned. If you could somehow run a region free player, any PlayStation 2 console would allow region-free DVD playback, not only Debugstation consoles. But remember, one cannot run such a thing on an unmodified retail set and Debugstation sets are incapable of DVD video disc playback.... SCE might have worked to prevent such a thing from happening anyway, by only enabling DVD video disc playback after a valid DVD player is first decrypted. But it has stopped being an effective measure, ever since people have discovered that loading EROMDRV (or any valid DVD player) would re-enable DVD video playback for any purpose (but oh wait, this doesn't work on debugstation sets!). This is also used for ESR. Even if CSS was long broken, SCE would still have to comply with local regulations in order to avoid legal trouble. If not, how do you explain why they had to take the trouble to replace the buggy DVD player v1.00 and actually ban it from use on all newer consoles? This conversation is really getting offopic now. If you still cannot agree with me here, we can continue debating via PM instead.
