Kevin Mellott has just opened a second batch of pre-orders on the HyperBoy+ = An updated version of the single-flash HyperBoy rom cart, that includes a 4-color, Black/White/Red/Yellow eInk screen. The price is about $200 and they should start shipping to customers before summer. More info below the link:

The ROM cart is the single flash version of Kevin’s HyperFlash32. That’s currently out of stock, but all ROMs can be loaded on a MicroSD card and you select the game with the eInk screen and capacitive touch buttons. This version is less expensive, but requires a PC app and a USB connection to load games. Once the ROM is loaded, the image will persist on the eInk screen permanently, essentially turning it into the game you’ve loaded.
