Assertion failed! with Visual C++ Runtime Library
Whenever I try to load a cart that I downloaded from Lexaloffle BBS site (.PNG files, not .P8 files), I get the following error..

Microsoft Visual C++ Runtime Library

Assertion failed!
Program: retroarch.exe
File: src/io/stegano.cpp
Line: 63

Expression: magic == expected

.P8 files work just fine though. Not sure if I should open the issue with RetroArch or not. Please let me know if that is the case, and I will close this one.
