GD-ROMs can be read with a few Plextor IDE CD burners and a patched firmware. You can't create them without GD-Rs, of course, but at least clone them for archiving and emulation. The common way is to use a program on the Dreamcast that slowly transmits the disc image via serial connection to the PC. The software side of the Katana is pretty much obsolete today as there are better Open Source development tools and libraries available, unless one really wants to utilize WindowsCE for any reason. The machine itself is just one of the most beautiful console devkits ever. Thanks for taking it apart :)

Out of the dev kits ive owned here are how they worked with or without a pc: The Nintendo NDEV (wii dev kit) needs a pc to even start and loads everything over usb very similar to the dreamcast to a degre. The Nintendo IS-NITRO-EMULATOR does not need a computer to boot and can play GBA games in this mode. To play DS games a computer is required to load a rom file but also needs a ds cart for saves only, this can be a dev cart or a retail cart with a compatible eeprom for the rom The Sony PSP Dev kit does not need a pc to do anything other than debug stuff. you can boot and use the menu as usual and even toss in a retail psp game in the UMD drive. The CD/DVD drive can also be used just fine as long as its a master disc. The SONY PS Vita dev kit does not need a pc to boot or to play games but does need a pc for debug stuff. Retail games could be played. I also had a test kit for ps3 and ps4, both could boot and run but the ps4 could do basically nothing unless it had proper game files for test kits. EDIT: Sony stuff used ethernet or usb for stuff depending on what was happening. PS4 could do menu things and such i just mean "nothing" for playing games unless they were the right package or disc type.

I love to see this DevKits, the way it's build says a lot about how hard it is to make a console.

Seeing you tinker with the hardware and software, instantly takes me back to that wonderful time of computing in 1999. Like finding the rights cables in a box or just experimenting in Windows to see what would happen. It still bugs me that Sega didn't outlived the home console market. The Dreamcast remains as one glorious piece of gear.

Gotta love the sound of a older computer/HDD spooling up during startup. Somewhere I got a old IBM 386 SX system with a big orange juice carton sized HDD… took damn near half a min to spool up. Sounded like a turbine engine.

There’s one on eBay someone selling for $5.5k (4.5k bid now), supposedly in working order and containing a prototype of the grinch. May be fake, but might be worth preserving too. Much as I want a dev kit to mess with one day.

Awesome video and very well explained :) .

Wow! Awesome teardown of this little gem. One thought about the GD-ROM drive: you mentioned that it is not ATA (or perhaps ATAPI) compliant. It might be possible to get it to work with a really OLD IDE controller (from the 386/486 days) that does not support ATA commands at all. Something by Winbond, Promise, or Data Technology come to mind. Mind you, though, that they would have to be ISA or VLB. Just a thought...😁

@NaokisRC

6 ай бұрын

It will certainly not be speaking IDE as that was only used for hard drives, all other PATA drives use ATAPI to tunnel SCSI commands as SCSI supports media like CD drives. But it’s probably deliberately made to not work with conventional IDE controllers so bootleggers couldn’t easily rip and replicate discs.

There's a performance graph on the right-hand side that doesn't appear in the PtoPOnline video and seems to be the main difference (except for the missing character models).

Sounds like a good use for a blue scsi emulator to replace the drive

the reason the dc controller had the cord on the opposite end, in cause people played with the controller in their lap, the corn coming from the top would pull it away from you when you didn the gamepad pull when jumping left or right, but when it comes out the bottom it pulled more into you hands.

For reference to the IDE drive chip, IDE CD drives actually use SCSI (yes, really, it's even possible for most OSes that support both SCSI and IDE CD drives to support obscure SCSI hardware that was _never_ available for IDE via an IDE SCSI converters... there's at least one soundcard, for example) transported over IDE, so all that's really needed is a _relatively_ cheap repackaging of commands.

Yes ATAPI is tunnelling SCSI over ATA Packets (hence the name ATA Packet Interface), but my comment was that the GD-ROM drive was an IDE/ATAPI standard when most consoles prior and of the time (excluding the OG Xbox) used custom and proprietary interfaces. That and the fact the fact could tie it to the GD-ROM system for the Naomi.

I love plop it's a great little utility except it doesn't work with one of my computers.

Also had the distinction of being the first laptop available with a DVD drive, USB and support for AC-3 audio. Fun computer over all.

@NaokisRC

Probably not a lot. Sega already had enough troubles with cash, getting a DVD license would put costs up, Sony would also have tried to stall production of the Dreamcast and even then the hardware in the DC was just not competitive with the rest of 6th gen consoles as GPU tech was accelerating fast. Sonic adventure 2 battle uses twice the amount of polygons for Sonic’s model on the GameCube compared to the Dreamcast, for example.

@goosebyte

7 ай бұрын

Technically not cds, but a halfway in terms of tech, they packed more than 750mb on the disc, and only the first bit of the disk counts as basically a mini cd, with the rest being GD and unreadable by most regular cd drives, without firmware hacks iirc it’s not possible even with compatible drives, but it’s been awhile. All I know is when you burn larger games to cd, you often sacrifice FMVs or music (quality lowered or removed/replaced by the smallest file. Sonic Adventure with every track being Station Square I remember VERY clearly……)

Besides the crack, I think you need the "System Disc 2" boot disc to load GD-Rs. If the drive can read through the crack, that might be the reason it's claiming it's not a game disc.

You could probably do it just with software - the GD-ROM electrical interface is PATA with a few additions (33.8868MHz clock output, a pre-emphasis enable line for CDDA and a serial transport stream that's basically I2S except the it has LRCLK lined up with first bit of each word rather than one bit cell earlier like Philipps I2S) - the software interface is sort of like ATAPI, but incompatible. Annoyingly, Sega called it "SPI" (for "Sega Packet Interface"), so searching for information on it tends to generate a lot of hits for the other better known "SPI" interface). Try searching for "cdif131e.pdf" - that should turn up the official Sega documentation for the command set.
