This a WIP PSX 3d engine. Use this with the companion blender exporter to create levels for the engine.

More video samples here.

Be warned this is WIP !

Real-time 3D / 8bpp background / 4bpp background

• UV textured models
• Vertex painted models
• Multiple camera modes
• Vertex animations
• Up to 3 light sources
• Use pre-rendered backgrounds (8bpp and 4bpp)
• Basic collisions
• Sound effects (VAG/XA)

• L1, L2 : rotate light matrix.
• R1 : Change camera mode.
• R3 (Dualshock) : Rotate camera in orbital mode.
• Up, Down, Left Right, L3 (Dualshock) : Move actor.
• X : "Jump" .
• Select : Switch level.

• Fix and improve all the things !

You need to install mkpsxiso and the Nugget+PsyQ SDK before you can build the engine. Put mkpsxiso and pcsx-redux in your $PATH and you should be good to go.

1. Clone this repo in your nugget+PsyQ folder as a new project :

git clone https://github.com/ABelliqueux/3dcam-headers --recursive my-project

2. Navigate to that folder in a terminal :

cd my-project

3. Type ./isotest.sh. This should compile the example, build an iso with mkpsxiso and launch it with pcsx-redux.
   If you'd rather do things manually or are using Windows, this script does 3 things:
   * make : compile the project
   * mkpsxiso -y config/OverlayExample.xml : create the bin/cue disk image
   * pcsx-redux -run -iso OverlayExample.cue : run the disk image in the pcsx-redux emulator.

On first launch, pcsx-redux will ask for a PSX bios. You can use your own or the open source OpenBios.
A prebuilt binary is available here for convenience.
Set it in pcsx-redux ; Configuration > Emulation, then reboot the emulator ; File > Reboot.

4. Install the blender extension to create your own levels.

If you have a real PSX, a cart flashed with Unirom and a Serial/USB cable, you can upload the demo to the PSX memory with NOTpsxserial.

The engine can use overlays to load data in the psx memory, so as opposed to a 'classic' project where you can just load the psx-exe in ram, we first have to load the data to a specific address, then load the exe.

First, comment out line 28 in main.c, so that the PSX won't look for the data on a CD :

// #define USECD

The address we have to load the data to is defined by the 'load_all_overlays_here' symbol in main.map.
The provided ovly_upload_helper.sh bash script takes care of finding that address depending on the ps-exe name.
Thus, to load Overlay.lvl1 and main.ps-exe in the psx ram, use :

./ovly_upload_helper.sh Overlay.lvl1 main.ps-exe /dev/ttyUSB0
