If the latter option is what we can expect, I similarly predict copies will be quickly snapped up by Saturn enthusiasts looking for a cheap way to play copies without more invasive hardware modifications or the few alternatives that are now rising in price as demand for these grows.
1) It's not exactly hard to find modchips or PseudoSaturns 2) There's nothing to say this cart will be usable for starting anything other than this game.
I'm thinking Cart only myself at this stage, flash memory is really cheap nowadays, kinda makes sense.
Without going into specifics, that "plug 'n' play" comment might indeed be a clue that we're looking at a cartridge only game...
One Twitter user asked him if he'd finally gotten round the issue of loading CDRs on the Saturn and he replied: "Of course, we'll release a plug and play game".
Cryptic or not, it would appear he's cracked it. I think he'd reduce his sales projections if he was to turn round later and say "By the way, you'll all have to buy an action replay or pseudo saturn cart too, if you want to play this".
He seems to keep dodging the CDR question so to me it seems like its a cart game too. I guess thats actually neat in some ways, if people just started making games as if the cart slot were made for gaming like we all thought when the system first came out. Turning the Saturn into a genesis lol.
That said if hes just staying quiet and in fact figured out how to produce legit Saturn CDs that would be nuts.
From what I recall of past attempts to bypass or at least document the Saturn's copy protection, there appears to be some type of holographic area the laser checks for at the boot stage, only this was supposedly pressed with a "wobble" of sorts in the track that makes it impossible for conventional disc burners to replicate. The only real alternative to this would be to circumvent such a test by tricking the BIOS into thinking the verification process had already been completed, which is how devices like Pseudo seem to work. Of course, this is only a very basic version of what's happening - I'm sure someone else will be able to provide much greater detail.
On the other hand, I once remember there being suggestions that it may be possible to create a self-booting disc by burning data to a smaller 8cm CDR then inserting this into the middle of an original Saturn disc with its middle section cut out. I've no idea whether anybody was crazy enough to try out this method, though I'm highly sceptical of this for various reasons. First of all, it would require a perfectly good disc to be sacrificed, not to mention you'd be limited to burning games with smaller amounts of data than a standard disc allows. Furthermore, this would surely put considerable strain on the drive motor. Even if it is achievable, I can't possibly recommend this as a solution. More than installing a mod chip, replacement SD card port or even flashing a compatible cartridge, such a necessary level of precise engineering is likely beyond the reach of your average gaming enthusiast.
