Kevin Mellott has just opened pre-orders on a rechargeable battery pack for the Wonderswan handheld console. This was designed to match the curvature of the WS Color, while maximizing the battery area; As shown in the picture above, this still leaves room to see the game cartridge artwork. This is intended for Wonderswan Color users who upgraded to a IPS screen kit.

Kevin’s also been working on an eInk-based ROM cart for the Wonderswan. While there’s no current timeframe for pre-orders or release, anyone who purchases one of these kits will be eligible for a 10% discount on the ROM cart when it becomes available – A pretty cool bonus!
