PCSX2_rewrite

An attempt at updating the PCSX2 codebase with 3 primary objectives:

• Use OOP design practices (in C++) instead of the large C type programming currently in use.
• Document as much as possible. Currently there is very little documentation on most things.
• Get rid of the bloat accumulated over 10+ years (a lot of this will be done through the use of OOP).
• Able to be compiled on popular platforms, such as x86-64 and ARM (including dynarec cores).

It holds the same license as PCSX2 (GPL-2+).

I am employed full-time, so I can only work on this in my spare time.

Current status

Status as of 2017/05/21:

• Primary focus for now is on the IOP, will continue on the EE side after.
• Work started on the SIO/SIO2 (controllers and MC's).
• Work started on the VIFs and VUs, mostly just implementing instructions left.
• Work started on the SPU2 (DMA and IOP communication done, sound generation still to be done).
• No work done yet on the IPU, GIF and GSCore.
• Everything else not mentioned mostly done (EECore, IOPCore, etc). Interpreters only for now, dynarecs will not come for a while.
• Multithreaded VM works, but is not polished enough for use (race conditions not handled yet, but should be easy/medium to fix).

Build Instructions

The project uses the following libraries as git submodules:

• Google test library (only for PCSX2_Core_UnitTest, you can build the Core and Frontend projects without).

The following command should be enough to get going:

marco@pc:/PCSX2_rewrite$ git submodule init && git submodule update

No support for big-endian architectures (yet), or when a float is not 32-bits wide (see the f32 typedef). See PCSX2_Core/src/Common/Global/CompileOptions.h for a list of debug options you can use.

Visual Studio 2017 (my primary environment)

Open the solution file and 'Build Solution'. 
Only the x64 platform is used by me, but any configuration should work.

GCC

Typical build command:
marco@pc:/PCSX2_rewrite/PCSX2_Frontend$ g++ -std=c++14 -g -O3 -D_DEBUG -pthread -I../PCSX2_Core/src src/PCSX2_Frontend.cpp `find ../PCSX2_Core/src -name *.cpp` -o pcsx2_frontend
(No build script yet.)

Clang/LLVM

Typical build command:
marco@pc:/PCSX2_rewrite/PCSX2_Frontend$ clang++-4.0 -std=c++1z -g -O3 -D_DEBUG -pthread -I../PCSX2_Core/src src/PCSX2_Frontend.cpp `find ../PCSX2_Core/src -name *.cpp` -o pcsx2_frontend
(Note the clang++4.0 and -std=c++1z option, using either clang 3.8 or the -std=c++14 causes it to fail, a bug report has been submitted about this.)
(No build script yet.)
