Project Deluge - 135 Dreamcast prototypes, 349 Xbox (OG) prototypes.

​ ​​ Project Deluge (Lot Page) Project Deluge - Microsoft Xbox (List) Project Deluge - Microsoft Xbox (Matched List) Project Deluge - Sega Dreamcast (List) Project Deluge - Sega Dreamcast (Matched List) Discuss this release on our Discord server!​ Hello everyone! It’s that time again! Continuing with our efforts with Project Deluge, today we present over 349 Microsoft Xbox prototypes and 135 Sega Dreamcast prototypes! From unreleased games to early builds, this lot continues to be fruitful. Some Dreamcast highlights include - Debug enabled builds of Jet Grind Radio and Illbleed, a unreleased English localization of Shangai Dynasty, an early build of 4 Wheel Thunder called Offroad Thunder, an early prototype of Deep Fighter with preproduction FMV, and more! Xbox highlights include - prototypes of Jet Set Radio Future, Crazy Taxi 3, Toe Jam & Earl III, Gunvalkyrie, and more. Prototypes of unreleased games such as The Vatz, Made Man, and Hail to the Chimp. Unreleased localization builds such as Dinosaur Hunting: Ushinawareta Daichi. As an extra treat, Laurent C. from Sega Dreamcast Info Preservation Games (https://en.sega-dreamcast-info-games-preservation.com/) has generously donated a prototype of ChuChu Rocket! and Sega GT as well! Huge thanks to all of our project members on a job well done so far! The project isn’t even close to being finished yet! Stay tuned for more in the upcoming months!

CPLD VGA Generator

Simply because I was told it couldn't be done — I built out a simple tile-based VGA video generator in a single 128 macrocell CPLD.

It generates VGA 640x480 resolution video at 60Hz using 8x8px tiles at 4 bit per pixel color. It supports selection of a single tileset for the entire image; or three separate tilesets, one for each horizontal third of the screen. Scrolling registers allow the image to be scrolled up to seven pixels horizontally or vertically. It still has some bugs in the CPU interface logic, but for a proof of concept I consider it a success.

It uses nearly all available logic in the CPLD, mostly for the registers used for counting pixels per line and lines per frame.

I started by laying out asynchronous logic in Logisim to see how feasible the idea would be, before transitioning to a fully synchronous design programmed in VHDL.

The project was challenging, but in the end it was easier than I expected. This simple design could easily be expanded in a larger chip (like an FPGA) to use multiple image planes, each with independent scrolling. A RAMDAC would be a great addition, since it would allow selection of 16 out of a much larger palette of colors, rather than the RGBB color I built around.

The iCE40 UltraPlus FPGA? Yeah, it runs Doom.

The efforts to elevate Doom from software to hardware continue. And this time, there’s a 22 minute video lecture on the process! Good stuff.

Thanks to Sylvain Munaut for submitting this!

Dreams Come True - Sonic 1 MD Prototype

Presenting, a prototype of Sonic the Hedgehog 1 for the Sega Mega Drive. Courtesy of Buckaroo.​ We couldn’t have done it without the cooperation of Xkeeper, Rusty, and the whole TCRF crew who have stuck with us for the whole ride. We’d also like to thank Sazpaimon (this is our wedding gift to you!), franz, ehw, the Hidden Palace crew and all of our contributors for helping the website grow. Without you guys, there is absolutely nothing we can’t do! Have a happy holiday, a happy new years, a happy 30th for Sonic. Let’s see what the next year brings! See you next game! Sincerely yours, Drx & ehw

Happy Holidays (2020)!

Happy holidays everyone! Santa came in the middle of the night and dropped off a few goodies under the Christmas tree. Presenting, a late prototype of Sonic Adventure 2, Sonic Spinball, and Mean Bean Machine! Enjoy!

Tune in for our last Twitch stream of the year tomorrow (12/31) at 2PM PST (5PM EST, 10PM GMT) for the unveiling of that last present from under the tree. I wonder what it could be?

Have fun!
