The mClassic is a compact, plug-and-play graphics enhancer that upscales and improves image quality from retro consoles, streaming devices, and PCs. Designed by Marseille Inc., it connects between your video source and display via HDMI, offering real-time processing without requiring software installation. This guide walks you through every step of setting up your mClassic in Hong Kong, from unboxing to fine-tuning settings for the best visual experience.

What You Need Before Starting

Before you begin, ensure you have the following items:

  • An mClassic unit (available at retailers like 2000Fun or Golden Computer Centre in Sham Shui Po, typically priced between HK$800 and HK$1,000)
  • An HDMI cable (at least one, preferably high-speed HDMI 2.0 for 1080p/1440p output)
  • A video source (e.g., Nintendo Switch, PlayStation 3/4, RetroTINK, or a PC with HDMI output)
  • A display (TV or monitor with HDMI input, supporting at least 1080p)
  • Optional: A micro-USB cable for firmware updates (not required for basic operation)

Step 1: Connect the Hardware

The mClassic is designed to be inserted between your source and display. Follow these steps:

  1. Power off your video source and display.
  2. Connect one end of your HDMI cable to the output port of your source device (e.g., the Nintendo Switch dock).
  3. Connect the other end of that HDMI cable to the input port of the mClassic (the port labelled 'INPUT' on the unit).
  4. Take a second HDMI cable (not included) and connect it from the output port of the mClassic (labelled 'OUTPUT') to an HDMI input on your TV or monitor.
  5. Power on your display first, then your source device.

The mClassic draws power through the HDMI connection; no separate power adapter is needed for standard operation. However, some users report better stability with powered HDMI cables or an optional micro-USB power supply (5V/1A) if the source provides insufficient power.

Step 2: Understanding the LED Modes

The mClassic has a single button on the side that cycles through three processing modes, indicated by the LED colour:

  • White LED (Default): Upscaling and anti-aliasing are active. This mode is suitable for most games and video content.
  • Green LED: Adds a 'retro' CRT-like scanline effect, ideal for classic 8-bit and 16-bit games.
  • Orange LED: Bypass mode — no processing applied. Use this if you encounter compatibility issues or prefer the original signal.

To change modes, press the button briefly. The LED will cycle through white → green → orange → white. Hold the button for 3 seconds to toggle between the current mode and the previously used mode.

Step 3: Optimise Your Source Settings

For best results, configure your source to output the highest resolution supported by the mClassic. The mClassic can accept input resolutions from 480i up to 1440p, but it performs optimally with 480p, 720p, or 1080p input. Here are recommendations for common devices:

Nintendo Switch

Set the Switch to output 1080p when docked (System Settings → TV Settings → TV Resolution → 1080p). The mClassic will upscale to 1440p or 4K depending on your display. For specific tips, see our guide on using mClassic with Nintendo Switch.

PlayStation 3

Go to Settings → Display Settings → Video Output Settings and select 720p or 1080p. Avoid 1080i as the mClassic handles progressive signals better.

RetroTINK (e.g., RetroTINK-2X Pro)

Set the RetroTINK to output 480p (for 240p sources) or 720p. The mClassic will then upscale to 1440p. For more details, read our comparison of mClassic vs OSSC vs RetroTINK.

PC via HDMI

Set your PC to output 1080p at 60Hz. The mClassic can also handle 1440p input but will not upscale further; it will apply anti-aliasing only.

Step 4: Fine-Tune Display Settings

Once connected, adjust your TV or monitor settings to match the mClassic's output:

  • Set your display to Game Mode or PC Mode to minimise input lag.
  • Turn off any additional processing features like motion smoothing or noise reduction, as they may conflict with the mClassic.
  • If using a 4K TV, ensure HDMI input is set to 'Enhanced Format' (sometimes called HDMI 2.0 or UHD Color) to support 1440p/4K signals.

Step 5: Test and Verify Operation

After setup, verify the mClassic is working:

  1. Press the mode button to cycle through modes — the LED colour should change.
  2. Observe the image quality: In white mode, edges should appear smoother, and fine details sharper.
  3. Check for any artefacts or flickering. If present, try a different HDMI cable or use the optional micro-USB power supply.

If the image does not appear, try the following:

  • Ensure all HDMI connections are secure.
  • Power cycle all devices.
  • Try a different HDMI input on your display.
  • Switch to orange (bypass) mode to confirm the source and display work without the mClassic.

Troubleshooting Common Issues

Below are solutions to frequent problems encountered by Hong Kong users:

No Signal / Black Screen

This often occurs with older displays that don't support the output resolution. Hold the mClassic button for 10 seconds to reset it to 1080p output. If the problem persists, use orange mode and check your display's EDID settings. For more help, refer to our mClassic no signal troubleshooting guide.

Flickering or Intermittent Signal

Try a shorter, high-quality HDMI cable (2.0 or higher). Also, avoid using HDMI switches or extenders, as they can degrade the signal.

Input Lag

The mClassic introduces less than 1 frame of lag (approximately 10-16ms). If you perceive lag, enable Game Mode on your TV and consider using a low-latency display. For competitive gaming, some users prefer bypass mode.

Incompatibility with Certain Games

A few games may exhibit graphical glitches due to the mClassic's processing. In such cases, switch to green or orange mode. For a detailed review, see our mClassic review from a Hong Kong perspective.

Advanced: Using the mClassic with an Upscaler

For the ultimate retro gaming setup, combine the mClassic with a dedicated upscaler like the OSSC or RetroTINK. The typical chain is: retro console → RGB/component cable → upscaler (e.g., OSSC) → mClassic → display. The upscaler converts the analogue signal to a clean 480p or 720p, which the mClassic then upscales to 1440p with anti-aliasing. This setup delivers exceptional image quality for classic consoles.

Firmware Updates

Marseille occasionally releases firmware updates to improve compatibility. To update:

  1. Download the latest firmware from Marseille's official website (mclassic.io).
  2. Connect the mClassic to a computer via micro-USB cable (not provided).
  3. Run the update tool and follow on-screen instructions.

Note: The mClassic works out of the box without updates; only update if you encounter specific issues.
