3dox – Xbox 360 New Years Day Pre-Release – V0.03
=================================================
Introduction
============
3dox – A 3DO emulator for your Xbox 360. Based on FreeDO/FourDO/3dox Xbox
About a year ago i became interested in porting FreeDO (the 3DO emulator) to
the Xbox 360. It turns out that incrediclint had an Xbox 1 port of
FreeDO/FourDO port up and running called 3dox. His source code in turn became
the core code that I then used for the majority of my work.
incrediclint stopped working on his Xbox 1 port due to the fact that it
would not run at a good framerate due to the limitations of Xbox 1 hardware.
The Xbox 360 port initally did not fare much better. Initially it would not
run. The FreeDO codebase is not Big Endian friendly. I quickly got it working
on big endian and found out that emulation performance was terrible.
Averaging 20-25fps.
Generally speaking, the CEL engine code is the main cause for performance
issues. I spent quite some time optimizing functions to be more PPC friendly
it helped gain 10-15fps or so.
At that point i tried some multi-threading but nothing seemed to help. So i
abandoned the project and tossed it in the not to 4x
