STEP-BY-STEP SETUP GUIDE FOR EACH CONSOLE

NES COMPLETE SETUP (10 minutes)

What you’ll need:

Step 1: Locate the AV port on your NES Look at the back of your NES. You’ll see a round connector labeled “A/V OUT.” This is where you’ll plug the Retro Fighters cable. It’s the circular multi-pin port—the only port of its kind on the back.

Step 2: Plug in the Retro Fighters HDMI Cable Take the Retro Fighters cable and push the circular connector firmly into the NES A/V port. You’ll hear a soft click when it’s seated properly. Pull slightly to verify it’s snug.

Step 3: Connect HDMI to your TV Take the HDMI end of the Retro Fighters cable and plug it into any available HDMI port on your TV. Most modern TVs have 3-4 HDMI inputs. Note which port number (1, 2, 3, or 4) for the next step.

Step 4: Connect Power Plug your NES power cable into the power port on the back of the console (it’s a barrel connector), then plug into a power outlet or surge protector ($15-25).

Step 5: Turn on TV and Select HDMI Input Press your TV remote’s “Input” or “Source” button. Select the HDMI port where you plugged the cable (e.g., “HDMI 2”). You should see a black screen or NES startup.

Step 6: Turn on your NES Press the power button on your NES console (top right). You should see the NES startup logo and menu screen. If you don’t see anything, check Step 5—you may have selected the wrong HDMI input.

Result: Your NES now displays in 720p HDMI quality. Games will look crisp and colorful on your modern TV.

SNES COMPLETE SETUP (10 minutes)

What you’ll need:

Step 1: Identify your SNES model The Pound cable works ONLY with original SNES hardware, not the SNES Jr revision or SNES Classic. Look at the back of your console—original SNES has a large, gray rectangular case. SNES Jr is smaller and darker.

Step 2: Locate the Multi-Out port On the back of your SNES, you’ll see a port labeled “MULTI-OUT.” It’s a large, angular connector. This is where the Pound cable connects.

Step 3: Connect the Pound Cable Align the Pound cable connector with the MULTI-OUT port and push firmly until you feel it click into place. The cable should sit flush with the SNES back panel.

Step 4: Connect HDMI to TV Take the HDMI end and plug into your TV’s HDMI port. Note the port number.

Step 5: Connect Power Plug your SNES power cable into the barrel connector on the back, then into a wall outlet or surge protector.

Step 6: Select HDMI Input on TV Use your TV remote to access the Input/Source menu and select the HDMI port where you connected the cable.

Step 7: Power On Turn on your SNES. The startup jingle should play and the menu screen should appear in brilliant color and clarity on your TV.

Result: Your SNES displays in component-quality video (superior to composite or S-video). Colors are vibrant, and image quality is noticeably sharp.

GENESIS/MEGA DRIVE COMPLETE SETUP (10 minutes)

What you’ll need:

Step 1: Check your Genesis model Original Genesis has a large, horizontal black case. Genesis 2 is gray and smaller. Pound cables work ONLY with original Genesis hardware.

Step 2: Locate the Video Output Port On your Genesis back panel, you’ll see a port labeled “VIDEO OUT.” It’s a large, angled connector. This is different from the AV port on other consoles.

Step 3: Connect Pound Cable Firmly push the Pound cable into the VIDEO OUT port until it clicks. The cable should be completely flush with the back panel.

Step 4: Connect to TV Plug the HDMI end into your TV’s HDMI input and note the port number.

Step 5: Connect Power Genesis uses a proprietary power connector. Make sure you have the correct Genesis power cable ($8-12), as using a different system’s power cable can damage the console.

Step 6: Select TV Input Use your TV remote to select the HDMI port where you connected the cable.

Step 7: Boot Up Turn on your Genesis. The startup screen should appear. You can now insert a game cartridge.

Result: Your Genesis displays in clean HDMI video with excellent color reproduction. Games like Sonic, Mortal Kombat, and Ecco look fantastic on modern TVs.

N64 COMPLETE SETUP (20 minutes – more complex)

What you’ll need:

Step 1: Prepare Your Workspace Before opening your N64, ensure you have:

Step 2: Remove the N64 Case Screws Turn your N64 upside down. There are approximately 5 screws holding the case together. Some may have warranty stickers over them (removing these voids warranty on vintage consoles, but most collectors don’t care). Use your Phillips screwdriver to remove all screws carefully. Place each screw in a magnetic tray or labeled container so you don’t lose them.

Step 3: Separate the Housing Gently pull the two halves of the N64 case apart. The motherboard will be visible. Don’t pull too hard—there are ribbon cables connecting components.

Step 4: Locate the RGB Video Pins Inside your N64, find the video output port area on the motherboard. The Carby comes with detailed installation instructions showing which 4 pins need to be soldered for RGB output. These are tiny pins on the motherboard—this is the most delicate part of the installation.

Step 5: Solder the Carby RGB Pins If you’re comfortable with soldering, use a basic soldering iron ($20-40) to attach 4 thin wires from the designated motherboard pins to the Carby adapter. If you’re NOT comfortable soldering, many Amazon sellers offer “pre-installed Carby” N64 consoles for $120-150, which is worth the convenience.

Step 6: Mount the Carby Inside the Console Once soldering is complete, position the Carby adapter inside your N64 case in a location where it won’t interfere with other components. Some people secure it with small adhesive mounting pads ($8-12).

Step 7: Reassemble the N64 Carefully close the N64 case and reinstall all screws. Make sure no wires are pinched between the case halves.

Step 8: Connect HDMI and Power Connect your HDMI cable to the Carby output, then to your TV. Connect your N64 power cable and turn on the console.

Step 9: Configure Carby (Optional) The Carby allows adjustments via on-screen menu:

  • Scaling: 1x (original), 2x, or 4x
  • Scanlines: On/Off (simulates CRT appearance)
  • Output resolution: 720p or 1080p

Experiment with settings to find what looks best on your TV.

Result: Your N64 displays in stunning 1080p video with no lag. Games like The Legend of Zelda: Ocarina of Time, Super Mario 64, and GoldenEye 007 look dramatically better than on original composite cables.

Time-Saving Alternative: If soldering intimidates you, purchase a pre-installed Carby N64 from Amazon sellers ($120-150). Slightly pricier, but saves 30 minutes and eliminates soldering risk.

MULTI-CONSOLE SETUP (CONNECT 2-4 CONSOLES TO ONE TV)

What you’ll need:

Step 1: Position Your HDMI Switch Place your HDMI switch box on a shelf near your TV, or mount it on the wall behind your TV with adhesive strips ($8-12).

Step 2: Connect All Console HDMI Outputs to the Switch For each retro console:

  • Connect the conversion cable HDMI output to one of the 4 ports on the HDMI switch (labeled 1, 2, 3, 4)
  • Label each port with a cable label maker ($15-25) so you know which console is on each input

Step 3: Connect Switch to TV Take a high-quality HDMI cable (6ft) from the HDMI switch’s “OUTPUT” or “HDMI OUT” port directly to your TV’s HDMI input.

Step 4: Power the HDMI Switch Plug your HDMI switch into power. Most modern switches have USB power (included cable).

Step 5: Test Each Console Turn on each console one by one. Using the switch’s remote control, click through each input port (1, 2, 3, 4) to verify each console displays correctly on your TV. You may need to adjust TV input to match.

Result: You can now switch between 4 different retro consoles using the HDMI switch remote, without unplugging and replugging cables constantly.

COMMON CABLE MISTAKES TO AVOID

Mistake 1: Buying a conversion cable for the wrong console model

Problem: You own an SNES Jr. (the smaller gray revision) and buy the Pound HD Cable designed for original SNES, only to discover it doesn’t physically connect to your console.

Solution: Always verify your console’s exact model before purchasing cables. Original models have larger cases and different port layouts than revision models.

Fix: Check our comparison table at the top for your specific console model, then order the correct cable.

Mistake 2: Assuming all HDMI cables are identical

Problem: You buy a cheap $3 HDMI cable on clearance and experience flickering, color dropout, or “no signal” errors with your setup.

Quality matters with HDMI. Budget cables have poor shielding and can lose signal over distances over 10 feet.

Solution: Invest in a certified HDMI cable ($8-15). It’s worth it for stable video.

Fix: Replace your HDMI cable with a certified, high-quality option.

Mistake 3: Trying to use a Genesis 2 with a Pound Cable (doesn’t fit)

Problem: You buy a Pound cable assuming it works with all Genesis models, but your Genesis 2 has completely different ports than the original Genesis.

Solution: Pound cables (and most specialty cables) work ONLY with original hardware revisions. Genesis 2 requires different converters entirely.

Fix: If you own Genesis 2, use the universal AV-to-HDMI converter ($15-25) instead.

Mistake 4: Not testing before installing permanently

Problem: You mount an HDMI switch behind your TV using permanent adhesive, run cables through wall conduits, and THEN discover the switch doesn’t work with one of your consoles.

Solution: Test everything with temporary cable runs first. Once you’re sure it all works, then invest time in cable management.

Fix: Before committing, spend 30 minutes with exposed cables to verify every component works together.

Mistake 5: Using undersized power supplies

Problem: You plug multiple consoles into a single cheap power strip, which overloads and causes intermittent video loss or controller input lag.

Solution: Use a proper surge protector power strip ($15-30) with adequate amperage (15A minimum) and separate outlets for each console.

Fix: Upgrade to a heavy-duty surge protector.

FAQ: RETRO CONSOLE SETUP

Q: Can I use one HDMI switch for 10 consoles?

A: HDMI switches typically have 4 ports (some have 8). You can connect up to 4 consoles per switch. If you need more, you can daisy-chain multiple switches ($35-60 each), though this becomes cumbersome.

Q: Do I need an external power supply for the HDMI switch?

A: Yes, powered HDMI switches require power. Most include USB power cables ($5-8 if you need a replacement), and can draw power from a nearby wall outlet or your TV’s USB port (if your TV has one).

Q: My console works fine on old CRT TV with original cables. Will HDMI conversion make it look different?

A: Yes. HDMI conversion upscales the original composite or component signal to modern resolutions (720p-1080p), which can look slightly sharper but also slightly different from original CRT appearance. Some collectors prefer this, others prefer adding scanline filters (built into premium converters like Carby) to simulate CRT authenticity.

Q: Can I use these setups with modern gaming capture equipment?

A: Yes. HDMI output from these converters works with streaming capture cards ($50-150) and recording devices ($100-300). Perfect for YouTube retro gaming content creation.

Q: Is the Carby soldering process actually difficult?

A: For someone with soldering experience: Very easy (5 minutes). For someone without soldering experience: Moderate difficulty (15-30 minutes). The 4 points are small but forgiving. Many Amazon sellers offer pre-soldered N64 consoles ($120-150) if you want to avoid soldering entirely.

Q: Will my TV automatically scale the picture correctly?

A: Depends on your TV model. Most modern TVs have automatic scaling that works fine for retro games. In your TV menu, look for aspect ratio settings:

  • 4:3 mode best preserves original retro game appearance
  • 16:9 stretching fills widescreen but distorts images
  • Zoom or Fit options help find the sweet spot

Experiment to find what you prefer.

Q: What if my TV is really old and doesn’t have HDMI?

A: You’ll need either an older component/composite converter ($15-30) or to upgrade your TV. Most non-HDMI TVs are from 2005-2007 or earlier and don’t support the signal types these modern converters output.

Q: Can I use these cables for Nintendo Switch or modern consoles?

A: No. These cables are specifically for original retro consoles. Modern consoles (Switch, PS4, Xbox One, PS5, Xbox Series X) have built-in HDMI and just need a standard HDMI cable ($8-15).

Q: How many feet of cable is “too long” for HDMI?

A: HDMI cables over 25 feet start experiencing signal loss with cheaper cables. Stay under 15 feet with standard cables, or use active HDMI cables (15-30 feet) if you need longer runs ($20-40).
