That is quite clever! Don't run without a valid logo, and therefore violate a trademark or copyright if your game is to run without permission. It's like DRM but enforced legally not technically.
- toast0 4y agoIt's clever, bur probably doesn't hold water legally, see https://en.wikipedia.org/wiki/Sega_v._Accolade https://en.wikipedia.org/wiki/Sega_v._Accolade
- MikeRichardson 4y agoSeems like you could easily find some random garbage image that also happens to pass the checksum.
- monocasa 4y agoIt doesn't actually checksum, but instead has a verbatim copy and does a memcmp over both.
