There is only one Homebrew development kit known for the PC-FX, which is based on the GNU Compiler Collection version 2.95.1. The Mednafen author began work on a library for the compiler called pcfxlib but it was discontinued due to lack of interest until trap15 started development of a new library called liberis. The toolchain is designed for a Linux environment, although it can also be used with cygwin. To date, no Homebrew titles for the PC-FX have been released, although Aetherbyte Studios and Eponasoft have both expressed interest in developing new software for the console.
