it's hardly outdated, but it is discontinued. acekard dropped it at the end of last winter and stopped production on the card. wood r.p.g. and akaio are the only firmwares that still support updates for it. akaio's r.p.g. support is 95% yellow wood goblin's fixes. the r.p.g. has a superior build quality to the ak2/2.1/2i, it has the onboard nand, and the mini usb port is great for homebrew development. however, the nand is delicate but i know more than a few people that actually fixed problems by formatting it using the panasonic formatter!
i was considering selling mine at one point but then yellow wood goblin put out a fork of gelu's code. my r.p.g. has life again!
