Micro Java Games Development explains game development for devices that support J2ME MIDP. The six parts cover a full range of topics, from a tour of all available micro-devices (Palms, cell phones and pagers), a discussion of software standards apart from J2ME (cell phones, messaging, I-mode and wireless enhancements such as Bluetooth), and available J2ME extensions (Siemans, Ericcson, Nokia), development tools and restrictions, to the creation of a meaty J2ME game!
