The core tier of the PS2 SDK: EE and IOP libraries and drivers, one package per module, resolved and built by ps2build with either the GCC or the LLVM toolchain.
Based on code originally developed by the ps2dev/ps2sdk project and its contributors. This repository is a permanent hard fork: it starts with fresh history and changes are not merged back upstream. It is not affiliated with or endorsed by ps2sdk or its maintainers; do not file issues about it against the upstream repository.
Code carried over from ps2sdk keeps its original license and copyright notices, predominantly the Academic Free License v2.0 (see LICENSE), with some modules under AFL-3.0, LGPL-2 or GPL-2. New code is licensed AFL-2.0 unless a file says otherwise.
