Cxbx is a discontinued high-level Xbox emulator developed by Caustik (Name: Aaron Robinson) and blueshogun96 for old Windows systems. A total of 5 games were playable, according to a compatibility list from 2009; though this dropped down to just 2 as of 2015. Work is continuing on a fork titled Cxbx-Reloaded.

History[edit]

Cxbx was first released as a proof of concept in August of 2002. This early version was capable of emulating various lighting effects from the Xbox development kit (xdk) "graphics tutorials". Turok Evolution was the only playable retail game on the original Cxbx emulator that Caustik left off from. Caustik's work on Cxbx ended in probably 2004, although, in September 2007, he had a since-disappeared blog report that covered the emulator in small detail. In 2008, another contributor nicknamed 'dstien' was shown to have made several patches that got some games to progress better in Cxbx like making Futurama playable. Caustik's last news update on his Cxbx website, that covered blueshogun96's progress work on another Cxbx branch, was uploaded on November 2009. Independent contributor blueshogun96 was known to have started improving his fork(s) of Cxbx from 2008, and have created many blog posts detailing the progress from 2009 up to 2015. His 2012 compatibility list showed that 5 Xbox games were playable, but, somehow, the playable games count dropped down to just two in his 2015 compatibility list - these two playable games were: Panzer Dragoon and Smashing Drive.

Emulation Code[edit]

As seen in the Progress page in Caustik's Cxbx website on the design goals of the original Cxbx software, quotation is below:

The basic theory behind Cxbx is a tasty blend of HLE (High Level Emulation), and extremely efficient direct code execution. Since the Xbox uses an Intel Pentium processor, a large percentage of the code (most importantly, the code that tends to eat up the CPU) can be executed directly. This means there is no need for DynaRec (Dynamic Recompilation), which saves alot of CPU and RAM. Emulators such as UltraHLE and Project64 have proven that High Level Emulation is a really great way to achieve high performance. Cxbx takes this idea and, because of the Xbox's architecture, takes it to the next level by combining it with direct code execution. The result is speed and accuracy.
