A mistake in implementing 0xFX55

[khengari77]

`
// FX55: Stores V0 through Vx (Vx included) in memory starting
// at addr I.
case 0x0055:
debug_print("[OK] 0x%X: FX55\n", op);

                for (int i = 0; i <= x; i++) {
                    V[i] = memory[I + i];
                }

                pc += 2;
                break;

`

shouldn't this segment of code be like this:

`// FX55: Stores V0 through Vx (Vx included) in memory starting
// at addr I.
case 0x0055:
debug_print("[OK] 0x%X: FX55\n", op);

                for (int i = 0; i <= x; i++) {
                    memory[I + i] = V[i];
                }

                pc += 2;
                break;`
