Homebrew PICA200 shader assembler
e152f4e626
- picasso now accepts several input files, which are each compiled
into DVLE objects inside the .shbin
- Uniform allocation is shared amongst all DVLEs.
- Constant allocation is private to each DVLE.
- Header file generation is temporarily disabled.
- New directives:
.nodvle
Disables the generation of a DVLE object for the current input file.
This allows sharing code amongst shaders.
.entry entryName
Specifies the name of the entrypoint procedure of the current DVLE.
By default it's 'main'.

Introduction
picasso is a PICA200 shader assembler, written in C++. The PICA200 is the GPU used by the Nintendo 3DS.
picasso comes with a manual Manual.md that explains the shader language. example.vsh is simple example that demonstrates it.
Building
A working C++ compiler for the host is required (Windows users: use TDM-GCC), plus autotools. Use the following commands to build the program:
./autogen.sh
./configure
make
Shout-outs
- smea for reverse-engineering the PICA200, writing documentation, working hard & making
aemstro_as.py(the original homebrew PICA200 shader assembler) - neobrain for making
nihstro-assemble, whose syntax inspired that ofpicassoand whose usage of boost inspired me to make my own assembler without hefty dependencies.
