About the Project
Description
Tyra is a project that allows you to easily create games for the PlayStation 2 console.
When I tried to make a game for PS2 a few years ago, I realized how many things had to be done to tame this exotic console architecture.
Decision was simple - I need to create an engine which will handle 3D file loading, 2D/3D rendering, animation, audio, handling between PS2 CPUs, synchronization.. It should be simple as possible - so people with no experience can create a simple game in a few hours.
And that's what Tyra is all about.

Built With
Acronyms
- EE (Emotion Engine) - whole set of processors and subsystems that make up the PlayStation 2
- EE Core - main PS2 CPU (c++ done here)
- GS (Graphic synthesizer) - configurable rasterizer and texture mapper. Has only 2MB~ memory for textures, but for the opposite have very high transfer rate, so you can switch textures in the blink
- VU0 - programmable (ASM) vector processor that is accessed by inline assembly code injected into C program.
- VU1 - programmable (ASM) vector processor, which is similar to vertex shader. Accessed via DMA.
- IOP - I/O processor which enables access to peripheral devices, such the game controller
