DIY 600 In 1 SEGA Master System Game Card - An Informative Review

I recently bought this after seeing others review it on Youtube and thought i'd make a review myself adding the answers to the questions and concerns you wanna know that the others never mentioned.

1. 600 or more SMS, SG 1000 & SC 3000 games all pre-installed in the SD card.

2. Comes with the SD card.

3. Works on a Master System model 1, Master System model 2, Mega Drive/Genesis with Master System/Power Base Converter, Analogue Mega SG and even the Master-Gear adapter for the Sega Game Gear.

4. Runs on the old flash memory technology running OS 8.

5. Can play whatever game is flashed to the Cartridge without the actual SD card being inserted into the slot.

6. Almost 3 times cheaper than an official Master EverDrive X7 from Krikzz and much cheaper than South American reproduction carts of hacks.

7. Can also add more games to the SD card yourself or can choose to even delete some.

8. Large ROMS up to 1 Megabyte work (Sonic Blast).

Unsure things:

Not 100% certain, but there could be a 1000 or 100,000 time write cycle limit attached to this.

Enjoy the review!
