NullDC DreamCast Emulator PS3 Port Update, BiOS Operational


Sponsored Links
224w ago - Update: Some pictures and a video (below) are now available of the NullDC Dreamcast emulator running on PS3 for those interested!

A few days ago we reported news that drk||Raziel is working on porting the Sega DreamCast emulator NullDC to Sony's PS3, and today he reports that the BiOS is operational and running!

Speaking to PSGroove, [Register or Login to view links] states, to quote: "Letsee .. oh wait, it cross compiled ! *yay* for uber portable code ;p Interpreter only / underclock 4x / no pvr rendering / no audio / no input. Bios intro runs fine, then gets on the clock dialog screen. YAY !"





Currently it is produced on a PS3 Debug unit due to its remote debugging, but the code will run on Retail PS3 consoles as well. Below is the log file for those curious, cool news indeed!

Another update:
Video of nullDC Dreamcast Emulator Running Games on PS3

For the last few weeks we’ve been helping drk||Raziel test and debug his nulldc emulator. We’re now pleased to exclusively bring you a video of it in action! Progress has been steady since his last update, showcasing the BIOS running.

Games are now running and all of the graphical glitches are now gone from the BIOS! This is still a very early build of this emulator, and it will be a few more weeks before this really gets to playable form. It is currently running very slowly, (7.5 frames per second), but drk||Raziel has not even touched speed optimization yet.

Also, many games have graphical glitches, sound is not ported yet, and most games don’t boot at all (mainly because they gripe about not having sound). However, progress is moving extremely quick on this project and it is shaping up very nicely! Below is a video of the emulator running Power Stone and Crazy Taxi and check out some pictures of it after the jump!

Please note video has been cut in a few spots, mainly when it is loading (it took a minute) the emulator at the beginning, and when it cuts to Crazy Taxi.

You may notice there are 2 faint black lines running horizontally through some of these pictures. These lines are not caused by the emulator. They are caused by the television set used in the demonstration, it is damaged and causing these lines.

Below is the video, and I added it to the first post as well.

Also I like the PS3 controller a lot better than the big clunky one for the Dreamcast.

Also the high-def ability will be a superb bonus Itchin' to play a bit of Jet Grind Radio! It's been WAY too long!!

Here is another update, I don't want to have 15 threads for this so I will add them all to this one until a release.

To quote from PSGroove:
We reported last week about drk||Raziel’s serious undertaking of porting the nullDC emulator to the PS3. drk||Raziel has again exclusively informed us of his latest development.

After many hours of debugging he has finally got the emulator running on the PS3! Currently it is just the Dreamcast BIOS running, but very impressive none the less! The BIOS still have graphical glitches, but understand this project is still very early in development.

drk||Raziel still does not have his own hardware to develop on, and still seeks donations. He is 2/3rds of the way to his goal of buying his own PS3.

Having his own hardware would greatly increase development speed, as currently all code must be sent off to be tested by others.
