== DETAILS Fixes a bug where content CRC32 is not calculated when content loading is done by the core instead of libretro. This impacts the ability to do accurate content matching on netplay. This notably affects MAME, but is by no means limited to MAME. Change summary: - adds a method to the crc32 implementation that calculates crc32 for a file (as opposed to an in-memory buffer) - fix a minor bug that would print the "core will load its own content" right before attempting to load compressed content - in the actual "core will load its own content" path, calculate the CRC32 and log it before returning == TESTING Tested locally on OSX: - loaded content - started netplay - confirmed CRC showing in netplay data - verified CRC32 against external crc32 tool
