# YaPang: matching decompilation of the PangYa client and renderer

> YaPang reconstructs the 2011 PangYa client and Direct3D renderer as C++ source checked function by function with objdiff against the original binaries. A separate JP client code area is functionally decompiled for a port. Third-party libraries are excluded from the decompilation.
