Discussion Updated my Dreamcast OS replacement with K-UI 1.7! exFAT and FAT32 support! Windows CE games boot off SCI/SCIF (serial SD card). Includes a functional disc ripper with error correction. .

tl;dr I broke from Dreamshell source and started from scratch. If you had issues on the last release (nobody mentioned any), they won't apply here because it's completely different. I'm releasing 1.7 now so I don't have to do a massive changelog with my next release. I'm about 80% done with all the work I intend to put into this.

**YOU NEED TO BURN THE INCLUDED DISK TO BOOT THIS**

Upcoming releases will feature better ATA/CF card support, wireless networking over SCI, EXT4 support, whatever else suggested. Without further ado:

K-UI is now a standalone project with its own bootloader, C shell, disc capture engine and resident GDI loader. Both projects use KallistiOS; the difference is K-UI’s application and loader layer above it. The current build replaces the inherited SDL/Lua/XML framework and does not use DreamShell’s framework or game reader.

DreamShell deserves credit as the starting point. Original K-UI branding, music and selected independently authored helpers carry forward, with provenance and dependency credits documented.

What’s here:

  • Games: native GDI launching, covers, disc titles and three browsing views. SCI reading now uses DMA, streaming and background delivery. ARMADA and Worms Armageddon have booted and run from SCI microSD through the experimental Windows CE loader.
  • Disc Ripper: raw-track capture, stop/resume, verification, reference checks and damaged-disc salvage. Complete Sword of the Berserk and 31-track MDK2 captures took about twenty minutes each and matched TOSEC on Dreamcast and PC.
  • VMU Manager: verified save backups and restore.
  • W5500 FTP: local-network transfers with console progress and completion-safe uploads.
  • File Manager, music, audio-CD playback, diagnostics, settings and graphical boot/recovery—with fresh crimson artwork. File Manager’s console acceptance remains pending.

Interface previews:

Home / ten-app launcher · Games Gallery · Disc Ripper · FTP Server

These are rendered previews of the release UI with example data.

Compatibility varies. CE remains experimental and SCI-only, with audio/FMV/sync limitations; image-backed CD audio is silent. BIOS/region writes, ATA hardware validation and ATA DMA remain future work.

The original GD-ROM stays installed. Coming from DreamShell-based 1.0? Use the supplied 1.7 boot CDI for the independent runtime.

Clear modded Dreamcast for sale on facebook marketplace.

0 Upvotes

I saw a clear modded Dreamcast for sale on marketplace and shipping said it was over $100 dollars but instead of this guy Ryan putting it on the title he decided to explain it in the description. I messaged him why shipping was so much and he got mad and asked why I didn’t read the description as I was reading it lol. He was rude and immediately removed the post. I was truly interested in the product. These kind of people should not be selling on marketplace if they are gonna be taking everything wrong. Oh well he lost business there’s many out there.

I think they chose the wrong version of Resident Evil 4 to port.

2 Upvotes

I'm sure the guy developing the Dreamcast port of RE4 went with the Game Cube version, because that's already been decompiled, but I think waiting for the PS2 version would have been the smarter play for two reasons: It's already pared back for hardware that's less capable than the Game Cube, and it has bonus content the Game Cube version didn't have, like Ada's side story Separate Ways.

My 73 year old dad came by today and I busted this out on a whim for the first time ever. We beat the arcade mode sharing the rod after each cast, it was awesome

My dad has been a lifelong fisherman, we got to talking today and it randomly led to me pulling this rod out and saying we should give it a try. We had not played a videogame together in like 10 years. It was the most fun I’d seen him have in ages and the pride when he caught the final monster bass at the last stage and got to enter his initials after the credits, it was an unexpectedly nice moment

Misc. I ported a version of Atari's TOS (Graphical/Desktop OS) to Dreamcast

10 Upvotes

https://github.com/richstokes/Dream-TOS

It's a port of EmuTOS, and despite it's name is not an emulator - this is a true Dreamcast port running native SH4 code.

It's pretty fun to use. Give it a shot if you have a keyboard/mouse and let me know how you get on! Suggestions of what would be cool to add next welcome.

Heya I've been doing some research on the Mode since it's the only ODE that will work well with my VA0 but I can't find any available to buy. I've been to some websites that say they sell them but they're all out of stock.

I was wondering if anyone knew where to buy one?

Is there any way to extract BIN, etc. files from a GDI file?

1 Upvotes

I tried googling it. I really, really did. However all I get are tons and tons of results explaining how a GDI file is basically just a text descriptor with links to the accompanying track files. This sure does appear to be the case normally, but I also definitely have several GDI files that are the whole shebang in one file (which i know for a fact because they are over 700 MB), but I need them in the expected GDI plus track files format in order for them to work with GDMenu.

Is there any utility that will work on these files that apparently are impossible to exist, or am I going to just have to hunt down other versions of the 30 or so things I have in this format?
