Dumping the NEC PC Engine YUV Table
- dafelst 5y agoThis is some top tier hacking and reverse engineering, incredible stuff.
- jeffrallen 5y agoHat tip to the original engineers, too!
- unwind 5y agoVery very cool and ambitious, it's always instructive (and somewhat scary) to see people mixing looking at the actual integrated circuit with low-level programming and spaghetti-style wiring to get information about. Anyway, not sure I understood the issue right, but shouldn't it be possible to at least get a decent approximation of the suspected color-mapping by just writing a program to display all 512 possible colors (it's 3-bit RGB) on screen, digitizing 1,000 frames of "pure" RGB output along with 1,000 frames of YUV, and comparing?
