DaggerXL is a Modern Daggerfall Engine Recreation for current Operating Systems and hardware – essentially it is a remake in the spirit of a port. It will ultimately fully emulate the game of Daggerfall and then optionally enhance it by refining existing features and adding new gameplay elements that were originally intended. The game will make use of hardware acceleration providing higher resolutions, color depth, greatly improved visibility, better texture filtering, enhanced performance and more. In addition DaggerXL will support full modability, similar to more modern Elder Scrolls games, using custom tools.

I’ve said in previous posts that I planned on completing the gameplay for the Beta – making DaggerXL a full DosBox replacement for Daggerfall. I also said that with the most authentic settings – extended features disabled – that DaggerXL would behave almost identically to Daggerfall, with the exception of fixing game breaking bugs like crashes and allowing the game to run at a fluid framerate without the gameplay elements messing up (no fighting with cycles or dealing with low framerate so NPCs can walk). What I haven’t said is how I am accomplishing these goals.

In the past I’ve done some reverse engineering of certain contained elements (like reading some table data from the executable) and spent a fair amount of time puzzling through file formats, testing stats and their reactions and so forth. But I’ve been working on something else without telling a lot of people that will help me make DaggerXL as accurate an emulation of the original as I want it to be, literally. To put it simply I’ve been decoding the original executable and reconstructing it in my own C code – completely (not just bits and pieces). Then I take that C code and modify or write the systems properly in DaggerXL, fixing game breaking bugs and refactoring to fit the rest of the game/engine. What this allows me to do is make DaggerXL just as faithful and authentic as a pure source port would be even without having access to the original source code.

During this process, I’ve been putting together a temporary executable (“DaggerfallDOS”) which I can run and verify that I’ve interpreted the code correctly. This uses just the original Daggerfall code – decompiled and rewritten in C – with the exception of OS calls and Windows boilerplate. I don’t plan on releasing this but all the code that goes into this is being used to make DaggerXL as authentic as a source port.

If you want an example, look at this page: Decompile-Example. It shows just one function, much much more of this process has been completed. And this code (and the functions that it needs that aren’t shown) were used to render this:

DaggerfallDOS

This is being rendered directly from the decompiled Daggerfall code, in addition the mouse and keyboard input works, you can select the appropriate option from the keyboard shortcuts or mouse. I’m currently working through from beginning to end, making sure that each part works properly by using the new executable. This means that with the Beta, DaggerXL will be 100% vanilla Daggerfall gameplay complete – and will be nearly 100% authentic with the appropriate settings. Of course the extended features I’ve already shown will still be available – higher resolutions, color depth, texture filtering, higher quality lighting, bloom, large scale terrain rendering, improved terrain heights and visuals and much more. :D This process is going extremely well and should be complete in a few weeks, after which I can release the Beta – after a short period of closed testing to get rid of any remaining unknown issues.

So what does this mean for the other games? Its quite simple – every supported game will be as good as a source port when they reach Beta, DarkXL and BloodXL included.
