Scrolling Up about chip-8 HOT 3 OPEN

@JohnEarnest thanks for the data! The @trapexit documentation you linked was a good chunk of my reference material (and debugging vs. other emulators). That page specifically calls out 0x00BN as a "scroll up" on the SCHIP-8.

I'm closing, assuming that you just misread something, but if I'm wrong, definitely re-open and explain what I missed. ;-)

Thanks for link to "quirks and undocumented bugs." I'll definitely give that a look-see.

My point is that @trapexit's documentation is incorrect.

The thread I linked includes information derived from a disassembly of the original HP-48 SCHIP interpreter demonstrating that it does not support an 0x00BN "scroll-up" instruction.

You'll also note that if you look at the original readme for SCHIP this instruction is not listed.

Ah, I see. Sorry, I misread the original issue.
