If you are still playing cartridges originally intended for the DMG or Pocket Game Boy, what are you playing them on and what palette do you use?

I'm using a front lit SP with the black and white palette but the color seems a little washed out. I have to say though that the games look beautiful when on my Super Game Boy when upscaled from RGB. I usually will go with either B&W or the green look of the original DMG with standard black border. Sometimes I use the outdoors border as well
