CHR-ROM
A set of sprites and tiles. Also the name of the file type that holds such
information. By loading a CHR-ROM, YY-CHR displays and allows editing of all
sprites and tiles within. Frequently called just a "CHR". The name comes from
the name printed on the ROM chip of the NES cartridge.
Color palette
A set of colors, each with a palette index, meant to color art assets in
video games. Palettes allow color at reduced storage.

Hexadecimal
A base-16 number format. "16" in "base-16" is written in base-10 (also
known as decimal), the usual format people write numbers. In hex, that number
is written "10". Since English has no numerals past 9 (the "1" in "10"
signifies "one set of ten", and the "0" signifiies "plus no extra", thus making
the English numbering system base-10), conventionally numbers 10 thru 15 are
written with the first six letters of the English alphabet. Thus, "15" decimal
in hexadecimal would be "F" (zero sets of sixteen plus fifteen extra) and "23"
decimal in hexadecimal would be "15" (one set of sixteen plus five extra). Hex
numbers are typically pronounced one numeral at a time ("3A" as "three-ay"),
and can have leading zeros, usually to signify memory size. Hexadecimal is a
convenient way to write and read 8-bit values since one byte of eight bits can
store one base-16 number.
