Dreamcast Conversion is a complete overhaul of Sonic Adventure DX that makes it look and sound like the original Dreamcast version of Sonic Adventure. This is done by reimplementing Dreamcast assets (levels, textures, sounds, object models, special effects and branding) in the PC version. The modpack includes optional custom HD textures for the majority of ingame menus and other GUI assets. A companion mod recreates events and challenges that were previously only available on the Dreamcast. All of the above (and more!) can be downloaded and installed in one go using a universal installer developed with this mod pack in mind.

Dreamcast Conversion and related mods are designed for use with SADX Mod Loader and the 2004 PC port of SADX. The installer can convert the Steam version of SADX to the 2004 version, which supports the Mod Loader.

Hi everyone!

Here's an update on the development status of Dreamcast Conversion and other related projects of mine.

Starting today I'm taking a break from hacking SADX. I'm pausing work on Dreamcast Conversion, Dreamcast DLCs, Sound Overhaul 2 and HD GUI 2, and putting these and other projects on hold for an indeterminate period of time. There are several reasons I decided to stop working on mods:

1) The mods are pretty much complete within the current limits of my knowledge and modding skills;

2) The mods have come to the point where their further updates depend on further development of other people's work;

3) I am about to get rid of my main computer - in about a month from now I won't have a proper computer for a while and I don't feel like making mods on my tablet;

4) Finally, I feel like I have exhausted my interest in SADX modding and it's about time I either find another hobby or at least take a long break.

This doesn't mean the projects are completely abandoned, however. The support infrastructure (online updates, issue tracker, SADX Mod Installer etc.) will remain functional. There are also a few things I feel I should add to these projects before I can leave them, so I will be watching the SADX hacking scene for a while to see if these updates are possible. Here's a list of things that will likely prompt me to update the mods:

  • DC Conversion: when the SL lighting system is understood well enough to enable its use in the Lantern Engine mod, I will update DC Conversion to ensure the lighting on all SL objects is accurate. I may also update PL Tool with SL file support.
  • DC Conversion: when the SADX D3D11 mod is complete and Lantern Engine is updated to support it, I will update DC Conversion to take advantage of proper order-independent transparency and enable things that were previously difficult to do (metal struts in Sky Deck etc.).
  • DC Conversion: Exant and I have come quite close to loading converted SA1 Chao models and animations in SADX, but the models are still not in the original SA1 format, and at the moment the game crashes after using them after a while. If further progress is made in this regard, I will update DC Conversion accordingly and/or make it work together with the Chao World Extended mod, and possibly restore more Chao stuff.
  • HD GUI 2: when the Mod Loader is updated to scale anything from the "unsupported assets" list here, I will update HD GUI 2 to add new assets for Chao, Game Gear menus etc.
  • Sound Overhaul 2: if a better way to rip SA1 sounds is found (for example, when audio emulation in the redream emulator gets accurate enough, or when the HighlyTheoretical plugin gets an update resolving its current problems with SA1 sounds), I will start work on Sound Overhaul 3, which will be even more accurate to the original game.
  • All projects: if a critical bug is found (triggering crashes, major inaccuracies, game-breaking bugs etc.), I will push a hotfix when I can.

Thank you for following me and playing SADX with my mods all this time. It's been two exciting years and I hope I will be able to make more cool SADX mods in the future. Until then, have fun playing DC Conversion and other mods, and stay tuned for updates, which I'm sure will arrive eventually.

All the best,

PkR

Hello! I have a question about the mod loader. When I boot up the mod loader it says that there's issues with updating the mods, yet whenever I select the check for updates bar it says that all my mods are up to date. I'm not sure if they really are because some still have their previous update version number. Also, can the mod loader update other mods that didn't came with the installer. I got some mods from a website called gamebanana and I'm not sure if those mods can update through the mod loader. Anyways, thank you for your hard work on this mod and I hope you can help me out.

It would've helped if you mentioned which mods were having problems updating.

SADX mods can have their updates configured in multiple ways, and different modders choose different places to host their mods: the updates can be self-hosted (like DC Conversion), they can be on GitHub or on GameBanana. All three support updates from the mod loader, but self-hosted mods can't be updated if the host goes down, GameBanana often breaks too and GitHub has a daily connection limit so if you check for updates too often it will block you and throw an error.

Anyway I don't really do tech support for the mod loader, so why don't you ask MainMemory or on the x-hax Discord/IRC? Discordapp.com

Sorry that I didn't mention any mods. The mods I'm referring to are are the Dreamcast mods such as the Conversion mod, lantern mod, etc. I'm sorry if I'm being a bit too vague, but it's mostly just the mods that came with Dreamcast conversion option when I first booted up the setup. Again, I'm sorry for being vague and thank you very much for replying back to me.

DC Conversion is self-hosted while Lantern Engine is on GitHub, so that suggests problems accessing both options. Maybe something was up with your internet connection or the Mod Loader was blocked by the antivirus/firewall when it happened? The updates are working fine on my end. If it happens again, I suggest you check your network connection and/or antivirus or firewall that might be preventing the Mod Loader from accessing network.

Also "Dreamcast conversion option" sounds like BetterSADX, if you're using that I suggest you switch to SADX Mod installer. I can't guarantee that it will fix your update problem, but it comes with the latest version of each mod for the time being - Moddb.com

Hi! I recently updated from w7 to w10 and when I start Sadx it looks with the DC textures... But some of them look very low quality. I have a 5:4 (1280x1024) display and I don't have any other mods apart from the DC ones. I have all mods activated and the ModLoader configurations at high. There's any solution for that?

Hard to say without a screenshot. The perceived "very low quality" could be missing anisotropic filtering, non-native screen resolution, and some textures in the game are blurry themselves. If it wasn't like this before upgrading to 10, I suggest using SADX Mod Installer in Preset mode with the "Dreamcast" profile, and also disabling "Fullscreen optimizations" in sonic.exe properties.

It was the anisotropic filtering :P
Thanks!

This mod is pure magic. I was wondering, though: after all of the unbelievable DC restorations made to the chao garden, I noticed the chao themselves haven't been retextured or anything. Think that might be a future addition?

That's covered in the FAQ, I don't have much else to say on the matter.

I looked inside the chao texture files, and it looks more than likely that they can at least be retextured. Any plans to restore some functionalities like the subtitle transitions and the music cutting out between sections of the hubs?
