hx8 ~ Haxe Chip-8 Emulator

hx8 is a simple Chip-8 emulator/interpreter written in Haxe, with Lime as the Input/Graphics framework.

Usage

When targeting native, hx8 accepts a few (optional) CLI arguments.

hx8 [--rom /path/to/rom] [--cyclesperframe X]

--rom specifies a ROM to load at startup.

--cyclesperframe specifies how many CPU cycles will be run every update cycle.

Controls

ESC to quit.

G to reset.

P to change the palette colors.

I to invert the colors of the current palette.

O to open the "Select ROM" dialog. (only for native targets)

The 16-button Chip-8 keyboard is mapped as follows:

[Chip-8]    [Keyboard]
0           X
1           1
2           2
3           3
4           Q
5           W
6           E
7           A
8           S
9           D
A           Z
B           C
C           4
D           R
E           F
F           V

Basically, the 4x4 block of 16 keys on the left half of a standard QWERTY keyboard makes up your Chip-8 keyboard.

Compiling

First, install the required dependencies. From the project root directory:

haxelib install dependencies.hxml

Then to compile, assuming you have lime-tools installed and the lime alias set up:

lime build Project.xml <target>

Current targets are:

• linux using Lime's Cairo software renderer (tested on Fedora 25), other desktop targets (Windows, OS X) should work theory
• html5 using canvas rendering - you can try this target in your browser right now, here!
