## Keyboard mapping
CHIP-8 systems used a hexidecimal keyboard with the following layout:
CHIP-8 systems used a hexidecimal keyboard with the layout shown on the left.
This is mapped to the physical keyboard as shown on the right.
|---|---|---|---|
| 1 | 2 | 3 | C |
|---|---|---|---|
| 4 | 5 | 6 | D |
|---|---|---|---|
| 7 | 8 | 0 | E |
|---|---|---|---|
| A | 0 | B | F |
|---|---|---|---|
In this emulator the following keys are mapped to the above layout:
|---|---|---|---|
| 1 | 2 | 3 | 4 |
|---|---|---|---|
| Q | W | E | R |
|---|---|---|---|
| A | S | D | F |
|---|---|---|---|
| Z | X | C | V |
|---|---|---|---|
```
|---|---|---|---| |---|---|---|---|
| 1 | 2 | 3 | C | | 1 | 2 | 3 | 4 |
|---|---|---|---| |---|---|---|---|
| 4 | 5 | 6 | D | | Q | W | E | R |
|---|---|---|---| |---|---|---|---|
| 7 | 8 | 0 | E | | A | S | D | F |
|---|---|---|---| |---|---|---|---|
| A | 0 | B | F | | Z | X | C | V |
|---|---|---|---| |---|---|---|---|
```
So to get "deadbeef" inside the emulator you'd have to type "rfzrcffv".
