Nintendo Gameboy shop Advance Action Replay TESTED

Product Name: Nintendo Gameboy shop Advance Action Replay TESTED
Action Replay only; Does not include the Gameboy SP from photos. Authentic Gameboy Advance (GBA) Action Replay. I haven't used this in years, and it's been stored safely in my home. Tested and confirmed working (as you can see from the photos). I'm willing to accept counteroffers but please no low balls. Feel free to message me if you have any questions! Edit: Added last 5 photos of the device working with a GBA cartridge inside (Sonic Advance 3). The 8th photo shows the codes applied to the cartridge. The second last photo shows the infinite rings code working (999 rings displayed at top left corner of the screen). The last photo shows invincibility working. When Sonic is invincible, he flashes constantly. It's hard to pick up on camera, but you can tell it worked because Tails' model is solid/more clear shop while Sonic looks faded/transparent.
