Aha! I knew that those little Mega Drive-esque horizontal slots had a purpose. When I was stripping my DC down yesterday I did speculate to myself as to whether or not they'd be used for the karaoke unit or the proposed Zip drive.

Nice piece Tom, but what an anticlimax. Disappointing that it's now simply a glorified paperweight. It seems kind if shortsighted that no media came packaged on the disc, but then again, even if the Dreamcast hadn't failed, I bet Sega weren't planning for people to be still using the Kara in 2015.

Nice piece of hardware, however why not to use a microphone, which served well for Seaman? ;)

The microphone that connects to the controller for use with Seaman has a different size of jack and isn't powered like the karaoke mic. I guess if you used an adapter the Seaman/Planet Ring may also work in the Karaoke Unit, and vice versa...but why would you want to use the smaller mic on the Karaoke Unit or the bigger mic with Seaman?

That's an interesting way of utilising the hardware. I'd like to keep this one as it is for preservation, but if I ever come across another it's something I will certainly consider!

Did this thing have it's own power supply like the mega drive add ons

It didn't come with a plug as I guess Sega assumed you would just use the one you already had for your Dreamcast. But yes, as pictured the unit is connected to the wall socket and the power is fed into the Dreamcast via the little power cable that goes into the console.

Hi, Tom!

"rumours that you can use the Sega Kara disc to play some sample songs are - as far as I can tell - completely untrue"

Many DLCs for Dreamcast (e.g., Samba de Amigo songs) were actually very small files to be stored in the VMU, so the actual content (already on the disc) would be "unlocked" by the game when it sees the file on the VMU.

Of course, there was no way for the Dreamcast to actually save any DLC except on the very small VMU. Unless the karaoke unit has some sort of storage, most songs should already be in the disc. Still, a few compressed songs (MIDI file and synchronized lyrics) could be downloaded and saved on the VMU, but that would be very limiting...

Anyway, did you check the contents of the disc?

According to the page product on Sega's website, it should contain at least 40 background videos, so the disc size would be considerable, but there should still be plenty of space for MIDI songs...

BTW, it would be interesting if you could provide scans of the manuals and song lists - I could only find a handful on Sega Retro.

And, since you have nothing to lose, why don't you mess around with the VMU file for Sega Kara? From what I saw it requires 60 blocs on the VMU... I would definitely try to check and edit the contents to see what happens.

Hi Ricardo, thanks for your comment. Interesting point - I can't remember if I actually tried looking on the Kara disc using my computer. Will give that a go. Also, I'll look into the VMU file. The scans on Sega Retro are actually of the unit I have - I scanned them and sent them to Doc Eggfan to upload! The manual with the song lists is about 200 pages thick though but I'm happy to scan selected pages and get those uploaded too.

After searching some more, I've found a few more evidences that there are no songs in the disc:

I wonder if it would be possible to find some of the original data available on the now defunct website. With that it would be easier to hack a new server...

Hi Ricardo,

Thanks for looking into this in more detail. I also have the complete collection of Dreamcast Express demo discs and I'm sure I saw something on one of them regarding the Karaoke Unit. When I get a spare minute I'll have a look through them again and make sure I wasn't seeing things. There's definitely some VMU stuff on one of them pertaining to the Dream Eye, but sure I saw something to do with karaoke too. Not promising, but I'll take a look...

OK, I couldn't help myself and got an image of the segakara disc! :)

Here's what I've found so far:

- The disc image I got support the VGA box.

- The program loads fine, but I can't use the Karaoke option from the main menu because it can't detect the add-on (which is expected, since I don't have one)...

- There are 123 background videos in .m1v format (MPEG-1, no audio, 256 x 176) on the root of the disc, providing about 4h14 of background and accounting for 602 MB of the 663 MB total content size.

- There is one .ASF file containing 401 .ADX files. I guess some of them are samples for reproducing midi files and/or other audio data, but most of them seem to be something else.

- Many other folders and files are for the Dream Passport 3.

- The SONGDATA folder contains 7 files:

- KYOKUKAN.DAT has some messages in Japanese ("thank you for buying this product", "you can already play 16000 songs and a hundred is added each month", "mind the volume to not bother the neighbors", etc.)

- Five other files with name M030000 and extensions: .A, .CMP, .STN, .TBG, .TRP. In total, they have 37.3 kB.

- SUPER.A, with 14.6 MB, is a song database. I wrote a small script to parse it, and it contains 15.751 song entries. For each song there is the title, singer, songwriter, composer, one line of the lyrics and more.

- There seems to be only one midi file in the disc: JINGURU.MID, with 90 KB, but it won't play with QuickTime or VLC, and when Windows Media Player plays it I hear only a brief chord.

So that's it, nothing exciting, really (but I had fun searching for many of the songs on YouTube)...
