SEGA Saturn Coding Contest (C4 - 2007)

Download and view the results here.


All prizes have been shipped!
I'm very happy that all the packages arrived at their destinations in Canada, USA and France without any problem. Four homebrew Saturn developers were equipped with the USB DataLink device, which is very useful for testing homebrew applications on Saturn.
The money prize transfers have been successfully completed as well. VBT donated his money prize to support the next contest, a big thanks to all your support, VBT!
So with that, the C4-2007 is finished in every aspect. Now there's a few months for people to rest a bit, until the next contest starts. See you at the next C4-2008, coming soon this year!

Ryo Suzuki, one of our judges, was missing his judge rating on the website. He told me, I had a look and couldn't believe that I had forgotten it somehow. The files were placed in a subfolder, because I received two text files from him, while the others sent in one text file. Anyways, there os no problem at all. I've added his ratings and they didn't change the ranking. However, the distance between first and second place became more clearer.

Yesterday, all prizes have been given over to the postal office, I expect them to arrive at the contestants within the next two weeks. Money transfer has also started last weekend and should be completed a bit earlier. Thanks to all contestants for their work, especially to vbt who has always entered high quality Saturn games. The last two years, he made significant contributions to the Saturn contest by entereing two entries.

That not enough, I couldn't convince vbt to take the money prize. I'll take it for the next contest!

Long time no see!
This website hasn't been updated since a long time, instead I was in contact with the contestants at the segaXtreme forum or via e-mail directly. Sorry for the lack of updates and promotion, this time I had only few time spare for these things, because my own entry demanded so much time.

To get you up to date: the contest is over, I have received six entries, five judges have rated the entries, extra points have been assigned as well and I have summed up the final points, so we know now who the winner is! Videos of all entries have been recorded and uploaded to youtube. The download package is available, too. Everyone can try out the entries on his own!

This year, the raw size of the entries is about 960 MB, a new record!!!! Judging with the new points based rating system is really exciting, as the battle for the first place is an absolutely close one: without extra points, two entries have got the same number of points (57). A draw decision, so the extra points have to decide.

The list of extra points has been updated with things I had promised in the SX forum a couple of months ago, but only those things that actually have an impact. It's the usage of homebrew libraries that is rewarded with an extra point, too. It was also suggested to give extra points for animations done without SBL or SGL.

The judges have done an excellent job! We have more judges than ever before and they supply us with comments that are worth reading and fairly balanced decisions. Next, the prize shipping will begin. I'm still waiting for two contestants to give me their contact details. So come on, don't hesitate, your prize is waiting!

Just as a side note: judging has been done with the original submitted entry, meaning one entry per CD. I have to say this, because there is still a little bug in teh Atlas bootloader that drives the C4 contest CDs, which causes some entries to not work as original and some others to not work at all. For this reason, entries that the Atlas bootloader is not compatible with are supplied as seperate single game CD images and all entries are being judged without any bootloader in use.

Okay, everybody thanks for your patience. Now it's time to play! Head over to the results section, to download the entries and to view videos and judge comments!

It's already been a couple of days since the 10 USB DataLink devices are finished. I have equiped them with a cable twice as long as the original one, as I do have enough flat cable for 40 units and the length can be increased without affecting the transfer reliability.
Just to clearly point it out: the Saturn USB DataLink is no invention of mine, it's hardware and software has been developed by gameofyou and it can be purchased at the officially website
Right from the start, I thouth of the Saturn USB DataLink device as one of the most useful things needed for Saturn development. But it appeared to be rather expensive, a reason why I haven't had one myself, for a long time. So I thought about ways to offer it cheaper. This Saturn Coding Contest clearly is a suitable event. So I ordered 10 times the kit version only, grabbed the rest of the components from different distributers all over the world and built the units at home. Don't worry, I know what I'm doing ;) .

From now on, I will start to work on my own entry. It'll be closely related to the Police Officer Smith game, a graphic adventure that we (Arnold and me) are working on, since almost 1.5 years.

Hello everyone,
I've had some nice progress building the Saturn USB DataLink devices that can be won here in this Saturn coding contest. Two weeks ago, I successfully built the first unit, it worked right from the start! I've used it intensively and it proved to be a very reliable and useful device. You can see it working here on this video:

This week, I managed to solder the remaining 9 units. My girlfriend even helped me to apply some of the neccessary modifications to the case, in order to fit the pcb in. So I'm sure in one or two days, the units are finished! Here you can see a work in progress picture:

Oh and by the way: I also made a little banner:

Happy coding and see you soon,

New prizes arrived! Arnold donated 5 very nice games for SEGA Mega Drive, plus a hint book. I put those six prizes in a seperate table, along with 7 of 10 USB DataLink devices. These prizes are independent from place/rank of your entry. Instead, everyone can win them by achieving 1-3 extra points.

All components of the USB DataLink devices have arrived, I start building some of them, now. See the mass of electronic components:

Added extra points for dual cpu usage and SCU DSP usage.
The new C4 - 2007 SEGA Saturn Coding Contest starts now. Have a look at the prizes, it's worth a try! Happy coding everyone.


The SEGA Saturn videogame system has been released in 1994. With it's 32-bit dual CPUs, two graphic processors, 16-bit sound processor, sound DSP and mathematical DSP, it's one of the most exceptional and interesting pieces of hardware that a hobbiest programmer can develop for. The wide range of original and unique peripherals like a NetLink modem, Floppy-Disk Drive, Video-CD MPEG cartridge, printer, link cable, lightgun, RAM extension cartridges made this outstanding entertainment system being ahead of it's time.

A lot of it's power and potential is still uncovered, due to it's limited lifecycle. This is both, the mission of this SEGA Saturn Coding Contest and the general opportunity of homebrew Saturn development: to unveil it's real power piece by piece.

For the third time, this SEGA Saturn Coding Contest will give birth to another batch of brand new games and demos to be played on the classic SEGA Saturn videogame console. With high-value prizes (worth 850,- Euro in total) it encourages hobbyist programmers to join the Saturn development community. The new well-thought extra points system supports existing homebrew Saturn developers to create even higher quality entries than before and to become better and better.

What's new this year:


There are two types of prizes to win: money prizes for the three best entries and a USB DataLink device for every contestant. To prenvent misuse, this very valueable and expensive item is only given away under this condition: get three extra points or become one of the three best entries

2nd place:
3rd place:

prizes for extra points:

These prizes are independent of  the rank your entry gets. Each of the prizes listed here costs a certain amount of extra points. No matter which place your entry scores, if you got some extra points, you can exchange them for these prizes. If multiple contestants want the same item, the one with the highest placed entry gets it.

USB DataLink device for SEGA Saturn

This is how it looks now. Building all 10 devices from these mass of electronic components will require some time though :)

Well, I though it'll cost less if I take the cheaper kit version, order electronic components myself and take profit from discounts I got, but unfortunately, it did cost a lot more. Anyways, you can get them for free in this contest!

Rating: points and extra points

The entries are rated in three categories: graphics, sound and gameplay. There are 1 to 5 points given in each category, the better your entry, the more points you get. Additionally, there are a couple of extra points that can be collected by implementing some advanced features, see below. All these points are summed up to determine the ranking.
