clrmame Discussion / CRC Matching on Zip archives
« on: 20 September 2019, 23:20 »
I know that the 7-ZIP DLL file can be used to check the crc32 value of the files within the compressed zip archive.
My question is when you have ROMs that require a header skipper (No-Intro NES), are the Roms being extracted during the scan? Must the ROMs be extracted to check the CRC value by skipping the first 16 bytes of the ROM file, or does it do the check inside the zip file without extraction?
