CHECKSUM different when different filenames?

Unread post by Tormentor667 » 04 Jul 2013, 22:38

Out of curiosity - and sorry for being so dumb :P - but is the CHECKSUM of a file the same if I rename it? E.g. turning "Turtles (Europe) (M5).gb" into "Turtles 1 (PAL) (M5).gb"?

Yep!, that's right, ECC and ECC2 are CRC32 "Hash" based and not namebased!, you can name your rom whatever you like (that's why it's so great! :lmfao: ), ECC and ECC2 will always find the right info, metadata, images, videos, for this rom if the CRC32 matches!

That's why ECC won't parse CUE or other plain text files, every changed byte results in a diffrent CRC32. :smartass:, i hope you understand now, so creating some solutions with those files is not very easy!
