Hyperkin RetroN 5 3-in-1 Adapter for Game Gear, Master System, and Master System Card

I wanted to write a review about this product just in case any retrofreak owners have been doing research and were wanting to play/collect game gear and master system games, I struggled to find a definitive answer on whether this was compatible with the retrofreak or not! I took a chance and bought one and can confirm this DOES WORK perfectly with the retrofreak!!! I would recommend getting this over retrofreaks own version because not only is it half the price, but this one plays the European carts for the master system, retrofreaks own version only plays mark III Japan carts due to having a much smaller cartridges slot.The only thing you need to be aware of is that your retrofreak needs the latest version of the firmware installed, this is very easy to do and the retrofreak site now has clear instructions on their English site. I saw many reviews saying this didn’t work on the retro freak but I suspect it was because they were running older firm ware. These adapters are just pin adapters and the retro freak and retron adapter have the exact same inner designs, it’s the firmware that needs the update to be able to read master system software. If you contact hyperlink they will tell you they don’t think it’s compatible with retrofreak but I can 100% confirm it does! Beautifully! Also looks better ;)

So got this to play master system games on retro bit. That works, there maybe cheaper options but it works and I presume on a mega drive as well.Game gear games read but graphics on some wrong and controller doesn’t seem to work for playing the games. This is warned In reviews but does allow you to test a game gear cartridge.

Excellent solution for playing Sega Master System Carts/Cards and Game Gear games on the Retron 5.Simply insert into the Megadrive /Genesis slot, insert your cart or card and your away.Well priced and is a well made sturdy piece of kit.Please note: I only purchased a Retron 5 recently and it arrived with all the latest firmware updates installed. You will need to update to the latest version if you have an older Retron 5 to allow the adapter to work.Purchased on Amazon marketplace from the States and arrived a day earlier than expected.

Great to play master system/game gear/game cards on the retron 5. Works perfectly and less bulkier than the official megadrive/genesis adapter.As always with the retron 5,easy to put carts in...slightly harder to pull them out. lol

I have a vast collection of Game Gear games and this adapter nearly played the lot, except all Codemaster games would not work for some reason, which was a real shame. An update might come out later for this problem but still, it was a great buy, recommended!

From my entire collection it only plays a couple of games... It does not even play Sonic 2 on Game Gear....

Very easy worked for me straight out of the box simple plug and play unit

This item pretty much works for 50% of my intended purpose (The Game Gear side doesn't function properly on the Megadrive).Additionally, I am appalled at the choice of delivery courier chosen for this. It took nearly 2 weeks past the initial delivery date to get this item to me.
