Share
MartZ Gaming tells you how they did it, from a broken Game Boy to an online store.
Introduction
Are you passionate about retro video games? Do you have a collection, or do you just love hunting for bargains on Wallapop or at flea markets?
So, turning your passion into a profitable business buying and selling retro consoles and games can be much more than a dream.
Myself, Marti (founder of MartZ Gaming), started with a simple , broken Game Boy I found on Wallapop . I knew nothing about restoration, websites, or SEO. But I did have one thing: enthusiasm, curiosity, and a desire to relive the history of video games .
Today, my shop receives orders every week and I help collectors find unique pieces.
Here I share a step-by-step guide so you too can start your own retro business.
Let's get down to business!
1. 📦 Get your first pieces (without breaking the bank)
You don't need thousands of euros to get started. You can start with:
-
Affordable lots on apps like Wallapop, Milanuncios, or Facebook groups.
-
Damaged consoles or games with potential (some just need cleaning or a replacement!).
-
Local flea markets or second-hand shops.
MartTip: Look for complete parts with box and manual , but don't discard the "dirty" or damaged ones: that's where the biggest profit margin lies.
2. 🔧 Learn the basics of restoration
You don't need to be a technician, but you do need to learn:
-
Clean cartridges with isopropyl alcohol and an eraser.
-
To test controls, cables, screens, and identify common faults.
-
To carefully assess the condition of a console or game (case, stickers, battery, etc.).
MartTip: There are thousands of tutorials on YouTube for restoring anything from a Game Boy to a PS1.
3. 🧮 Keep track of your purchases and sales
Use an Excel spreadsheet from the start with these columns:
-
Product
-
Purchase price
-
Sale price
-
Expenses (spare parts, shipping, commissions)
-
Net profit
This way, you'll know which products offer the best margins and can reinvest wisely.
4. 🛍 Create your identity (personal brand or store)
You can sell from your Wallapop or Instagram profile, but I recommend:
-
Create a catchy name (like MartZ Gaming 😎).
-
Design a simple and recognizable logo.
-
Use Shopify or WooCommerce to have your own online store.
- Always tell the truth to gamers, if you have any mods or non-original parts, be sure to mention them to avoid misunderstandings!
SEO Tip: Always include keywords in your titles and descriptions: “original Nintendo 64,” “Spanish edition Pokémon game,” “original Game Boy.”
5. 📸 Take good photos and take care with the descriptions
Presentation is EVERYTHING:
-
White or plain background, good light, several photos (front, back, details).
-
Clearly indicates the condition of the product.
-
Describe if it is a PAL/Spain version, if it comes with a box/manual, and if it has been tested.
Plus: You can record short videos showing it turning on and working.
6. 🚀 Post on multiple channels and gain visibility
Don't stick to just one platform. Use:
-
Wallapop
-
Your online store
-
Instagram or TikTok to showcase your work
-
Forums like Elotrolado or collectors groups
And, little by little, position your website/blog with useful content like this 😉
Conclusion
Starting a business buying and selling retro video games isn't easy , but it's an exciting adventure if you love this world.
