This Wonder swan color is real housed in the smoke gray shell along with the MS-063 Zaki II front glass. This does not come with a custom boot ROM like the original special edition Wonderswan. Upgrades done to this system.
New lcd with touch brightness, color palette control
upgraded button pads
New injection molded shell
New front glass
New buttons with membranes
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.
