This Wonder swan Crystal has been upgraded with a new front glass from the limited edition one piece version along with a brand new IPS screen. This does not come with any game game is used for demonstration purpose only. Both touch sensors are installed one is in the center on the top where the cartridge slot is this will adjust your brightness levels the color palette sensor is to the left side of the cartridge slot this will allow you to change color palettes easily.
It's recommended you upgrade the battery pack to a rechargeable battery pack due to the IPS screen draining batteries exceedingly fast. I personally use the retro onyx rechargeable battery kit. Link provided below.
