PSn00bSDK | powerful source SDK for the PS1

PSn00bSDK is a C library. PSn00bSDK has no bugs, it has no vulnerabilities and it has low support. However PSn00bSDK has a Non-SPDX License. You can download it from GitHub.

PSn00bSDK is a 100% free and open source SDK project for the original Sony PlayStation for developing homebrew applications and games for the console 100% freely. This SDK can be used for freeware, commercial, and open source homebrew projects. The SDK is composed mainly of libraries (libpsn00b) and some utilities that provide a basic framework for developing software for the PlayStation hardware, the compiler is separate (GCC) and should be acquired from GNU. The library API is intentionally written to resemble the library API of the official libraries as closely as possible. This design decision is not only for familiarity reasons to experienced programmers, but also so that existing sample code and tutorials would still apply to this SDK, as well as making the process of porting over existing homebrew originally made with official SDKs easier with minimal modification, provided it doesn't use libgs. PSn00bSDK is currently a work in progress and cannot really be considered production ready, but what is currently implemented should be enough to produce some interesting homebrew with the SDK, especially with its extensive support for the GPU and GTE hardware. There's no reason not to fully support hardware features of a target platform when said hardware features have been fully documented for years (nocash's PSX specs document in this case). Most of libpsn00b is written mostly in MIPS assembly, moreso functions that interface with the hardware. Many of the standard C functions are implemented in custom MIPS assembly instead of equivalents found in the BIOS ROM, for both stability (the BIOS libc implementation of the PlayStation is actually buggy) and performance reasons.
