May I also ask how it's possible to find these things in an unrelated prototype game? I am aware this has happened before, but exactly how can data from proto game X from company A be found in proto game Z from company B? And in such (relatively speaking) good state? I don't know anything technical about dumping from cartidges, sorry if it's a dumb question.

Amazing find, evilhamwizard!

Various reasons. What's most likely in this case is that the individual responsible for either compiling the ROM or interweaving the EPROM binaries together to create a single ROM used a program that didn't release memory properly. So data from a previous ROM is kept in memory and inadvertently filled the regions of the Yu Yu Hakusho ROM that were meant to be padded with null bytes. This was most likely caused by someone who was responsible for managing the ROMs for Sega Channel and not the developer of Yu Yu Hakusho (Treasure).

If that's the case, does that mean that whoever managed the ROMs for Sega Channel had access to the Sonic Crackers build?

I'm amazed at the fact we found this, but also kind of disappointed that we may never find the full build.

BTW, the information from this latest leak is helpful for identifying things from prior leaks as well.

For example, the June 12th 1995 "Sega Channel" Comix Zone Prototype?

Take a look how it plays.

This looks like it matches up VERY WELL with the "Comix Zone Page 2" Test Drive entry for July 1995.

Are there any others I should look out for?


This is probably not confirmable in any solid manner, but my suspicion is that the Japanese ROMs in this set were all intended for Japanese Sega Channel.

When you compare what the ROMs are to what the confirmed Japanese Sega Channel game listing has, it looks like a solid chunk of them have already been listed elsewhere as being in Japanese Sega Channel at one point before. As far as I can tell, here's what is in the folder that is NOT listed (excluding the obvious Sega Channel-intended ones, gcan_sp, nyushi and planet) :

1) Puzzle & Action - Ichidanto-R (Danto)
2) Power Instinct (Gouketu)
3) Janou Touryuumon (Jannou)
4) Langrisser II (Lang2)
5) Assault Suits Laynos (Laynos)
6) Puzzle & Action - Tanto-R (Tanto)
7) YuYu Hakusho Prototype (Yuyu)

It's probably gonna be difficult to either confirm or refute this, but I would imagine if there's any evidence trail possible to pick up regarding this, it'd be in the Kyuukai ROM, since that is a game that was listed as being on Japanese Sega Channel before this was found, but has a different ROM than what the retail game has.

It might be worth noting that Danto and Tanto are first-party Sega, and Langrisser 1 being confirmed on Japanese Sega Channel makes 2 very plausible anyway.

HPZ is going to write an article on this soon. We are still researching all that was in there, but we identified all the playable ROMs at least.

A couple of unique Primal Rage ROMs:
Posted Image
Primal Rage (Test Drive)
Primal Rage Showdown
Primal Rage (Rental Version)

The first is a series of ROMs that were used in an event to showcase the upcoming release of Primal Rage. An event was held starting August 1st to August 25th to allow subscribers to play a “Test Drive” version of Primal Rage in preparation for Primal Rage Showdown, an event that challenged players with a very tough fight for a chance to a win a Primal Rage arcade machine, along with 150 other prizes as well. The event was held on August 25th, and was followed by a rental version of Primal Rage with certain features cut that was only available for 24 hours. This version would also be used in subsequent months on Sega Channel as the main Primal Rage ROM.

Posted Image
Planet Message Quiz
Included in the archive is a folder of ROMs used for the Japanese release of the service. The service in Japan would sometimes offer unique games that have not been released or seen since. One of these is a game called “Planet Message Quiz”, a quiz game created to educate players on the solar system. This is the first time this game has been offered since the service went live years ago and would've been lost since.

Posted Image
Nyuushi Chokuzen Check Nanmon Kimon Kiki Kaikai
Another special exclusive Japan-only game released in the service. This quiz game seems to have been created to test cram school students in Japan to help them pass their exams. This is another game that has also never been offered since the service was live.

Posted Image
Kyuukai Douchuuki (Prototype)
A possible prototype or second revision of Kyuukai Douchuuki was included in the archive for some reason. Out of all the games included in the archive (save for Primal Rage and the Sega Channel test ROMs), this was the only ROM that did not match the final released ROM. It only contains code differences, so we're not sure if it could be a prototype in disguise or just another revision (the header hasn't been changed to reflect this if it is).

Posted Image
Sega Channel Test ROMs
Included in the archive were many test ROMs that tested various menus throughout 1995. Aside from having access to the games, each ROM is essentially a time capsule as to what the service offered that month to its subscribers.

All the other ROMs included either match the final or are non working (there were some game help test roms that didn't work, save for one). We're also working on documenting all of the game guides as well. We've been working on this for several days so please stay tuned.

Awesome stuff!

Product codes;

Nyuushi Chokuzen Check Nanmon Kimon Kiki Kaikai: T-19401
Planet Message Quiz: T-19402

T-194 was the code for We Net (ウイネット), who's name can be seen on those title screens. The only title that they were previously documented for was "Cubic Gallery" (1996-05-17) on the Saturn. It looks like Edutainment titles were their thing.

FEBSAMPL.BIN is January 1995, but it has the background for February 1995. The original background looked like this (New Years celebrations);

Posted Image

No ROM for February 1996, but 02MTCK96.RTF and GUID0296.RTF contain the contents for that month, it's possible that the graphics are included in other files, so it might still be possible to compile that month. I've updated the US schedule with the missing months from December 1994 - February 1996.


SEGA CHANNEL GAME GUIDE To return to Now Playing, reset your adapter.

It's interesting to see that the guide seems to have been a separate rom loaded in the same way as a game, thus requiring resetting the adapter to return to the main rom. It should be pretty simple to emulate loading the guide and games when those are selected.

There was a Mega Drive demo of the Pico title "The Berenstain Bears' A School Day", I don't think that was documented before.


This is a version of a game available only on the PICO.

The PICO is a learning device with storybook sotfware from Disney, Richard Scarry and more. Kids from 3-7 can count, spell, play games and animate their own cartoons. Plug into PICO, the computer that thinks it's a toy.


Only on Sega Channel! Preview the new PICO game Berenstain Bears' A School Day! Run the obstacle course or two other activities in this game made for Sega's PICO Educational toy!


Berenstain Bears' A School Day invites children to join their favorite bears for a day at school. You can play alphabet catch, run an obstacle course, and run a red light, green light race.

All of these exercises will offer plenty of positive reinforcement by giving children repeated opportunities to master each activity.

The skills and confidence that children build as a result should help to fuel their curiosity and desire to learn.

A day with the Berenstain Bears will show your children that school can be an exciting adventure and that learning can be fun!


Berenstain Bears' A School Day

Garfield: The Lost Levels;


If you want to play a game that nobody else can, check out "Garfield: The Lost Levels" in the Test Drives category this month. This special version of Sega's new Garfield game has three levels not available in the retail cart!


If you get a kick out of Garfield, the crankiest cat around, then you're gonna love Garfield: The Lost Levels. These are levels that can't be found anywhere except on Sega Channel. So jump into Test Drives and get lost in Garfield's world.


This is a Test Drive of Garfield: The Lost Levels. This version of the game contains only three levels to play.

All of that Garfield text is on the CD? Did it come from any of those GARF files?

I wish there was a remote possibility the ROM is hidden in there somewhere.

They're just text from the sega channel files, game roms were loaded separately. The Lost Levels first appeared in February 1996, there isn't a rom for that month, and that's the last month there are any files for unfortunately.

EDIT2: howard #5 is fucking "Boss Opera" from Virtual Sonic.

Did we just come across source files for Virtual Sonic?

Boss Opera was found in the Comix Zone prototype many many years ago. Sound code #22 on the Comix Zone Beta is also a damn catchy tune, check it out.

Soooo.... was the entire Virtual Sega composition just converted GEMS files?

At least four of the songs was! Boss Opera, Spinball theme, Toxic caves, and the Sonic & Knuckles theme.

No, not just Virtual Sonic, "Virtual Sega", which was a bundled album line. The albums included are Virtual Sonic, Vectorman, Toejam & Earl (Sega Chanel), X-Men 2: Clone Wars, and Comix Zone.

They literally threw GEMS files to create the album. I wonder if all the samples could be found and studio quality versions of the Virtual Sega album line could be remastered!

EDIT: Has Nemesis been alerted that SEGA.EXE has been found? They considered this a top-priority above all else iirc due to it's specific nature in relation to development.

With regards to the GARF1220 file, presumed to be Lost Levels build 95.12.20 (retail Caught in the Act rom is 95.09). This Sega of America QA video from 1996 (filmed June 95 - Feb 96) features them downloading the latest builds in order to burn and test them. One of the files on the monitor is named "GARF1208" (Dated 12-08-95);

Ah! That appears on the Virtual Sonic album called "Boss Opera". The whole album is composed by Drossin.
