# HelloPSP-Recomp
Manual recompilation of HelloPSP (Hello World PSP)

The main goal is to translate lines of MIPS assembly to C by hand and get an accurate frame output.<br>
At the moment the VRAM section of memory gets built correctly at runtime. However the execution speed is way faster than the original.

Next goals:
  - Implement a timer to match execution/frame speed
  - Use a GUI/graphics library to display the VRAM pixels
