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 called 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

- 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

I have this same problem. I downloaded a lot of games on 3dox iso emulator. I threw them into the folder roms and wanted to move to disk via ftp HDD1, unfortunately, a message pops up when copying iso (invalid file handle). Iso files copied to an external drive and I wanted to copy them in FSD unfortunately when you try to copy, nothing moves, I used the XEXmenu and also nothing happens. Do you know how to help me? I'm sorry my English is poor.

Ps. I downloaded pack of games Thepirate... A Huge Collection Of 3DO Games + Emulator & Bios partI/partII/partIII .

Now I downloaded another game (from another source) and is easily copied. The problem probably lies in these games.

This is fantastic for a prerelease! I just hope this isn't abandoned like most 360 emulators. Any idea how things are coming along? Is there a way to donate to this project as I would definately throw some cash his way!
