xCHIP

Accurate CHIP-8, CHIP-10, HIRES CHIP-8, CHIP-8X, SUPER-CHIP, and XO-CHIP interpreter in Rust.

Features

• Simple flicker reduction ­— 10-20 instruction delay from a pixel being turned off to it actually turning off

Mode

The file extension is normally looked at to determine the operation mode of the xCHIP interpreter. To force the selection of a specific mode, use -m <mode> at the command line.

Name	Mode	File Extension
CHIP-8	chip-8, 8	---
HIRES CHIP-8	hires-chip-8, hires	---
CHIP-10	chip-10, 10	.ch10
CHIP-8X	chip-8x, 8x	.c8x
SUPER-CHIP	super-chip, sc	---
XO-CHIP	xo-chip, xo	.ch8

• CHIP-8 and SUPER-CHIP are subsets of XO-CHIP

• HIRES CHIP-8 is detected by checksumming the bytes from $200 to $240 as HIRES CHIP-8 ROMs officially started at $244 (memory before is for the interpreter but is included in all known ROM distributions for ease of loading in CHIP-8 interpreters)
