EZ-FLASH Omega Definitive Edition Micro-SD Card Adapter

As far as GBA games for sake of simplicity goes it works out of the box.
if you want to use Cheats or GB/GBC games it gets glitchy sometimes.
But pretty solid product.

The case for it seems very flimsy, moves around a lot when inserting/removing from console. The actual solder joints on it look pretty rough. Doesn't have the ability to change resolution of gameboy games to fit a GBA screen, but I don't think any flash carts have that as it doesn't exist in any emulators. Does what it needs to do, doesn't have any save file corruption issues as of yet, clocked about 30 hours on it. Pleased with it overall.

Amazing flash cart for playing GBA roms. But only decent at playing GameBoy and Color roms, some of them would glitch out

The Omega is easy to get going, has an uncomplicated and not gross for once UI, and just works! I was up and running in less than 5 minutes, and it's a blast to have multiple games ready to go.

If the budget is not a concern, just get this one also, it takes less power than ai,r as air is power hungry

Great product and fast shipping
