first post here
I've ported 3dox (incrediclints port) to the Xbox 360.A year or so in the making (not full time though ) i feel its finally good/fast enough to release to the masses.
If you have a JTAG/RGH'd Xbox 360 check it out!
here are the release notes for it
Code: Select all
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 release pile" due to the fact that the performance was still not great (35-40ps on average) Fast forward to December 2012 - I decided to take another look at the sourcecode and see if i can speed it up. Long story short, with a clear head and a fresh look at the code. The idea was to thread the DSP and CEL emulation. Some pain along the way but threading was implemented and working nicely- Now emulation is (generally) at 60fps. So welcome the new year with a new emulator for the Xbox 360. Remember this is a pre-release :) Features ======== - Fast 3DO emulation. - Full graphics/sound support - NVRam saving. - Pixel Shader support. - Big Endian friendly (PS3/Wii/Wii(U) port anyone?) - Source code released. Pre-Release Info/Issues ======================= - 1p controller support only at this time. - Sound has issues (scratchy/off pitch/generally pretty bad). - Random pauses and stutters occur. - Performance issues with some games. - Savestates are not implemented. - .ISO extension and .BIN extension are supported only - The launcher will load games only. There are currently no other options. - There are graphics issues. Wrong color palette at times. Theres still endian issues to address. - Game specific timing fixes are not implemented. - Pixel shaders are working but you cant select one. For now you need go into the shaders folder and rename/copy the shader you want to use and call it 'default.fx'. I've included CRT, HQ4x shaders to use. Installation Notes ================== - Place 3DO bios file inside bios folder. File MUST be called bios.rom - Roms go in the Roms folder. Files must be .ISO or .BIN otherwise they wont work. - Run 3doLauncher to start. - Press 'A' to launch the rom. While in game - right thumbstick to quit back to launcher. Controller Mapping ================== Game Select Screen: A: Launches the game. In-Game: B = A A = B B = C Start = P Back = X Left Trigger = Left Button Right Trigger = Right Button DPad = DPad Right Thumb Stick Click = Exit to launcher
and finally check out a WIP video of the emulator in action. The sound still needs work but you get an idea of how its running.
you can find it at the usual places - source is included
