Unfortunately Battle Kid is still only out to a select few, the rest of us unworthy monkeys out here are still left waiting for a reprint of the manual, which seems to take quite some time and it's the reason why the monkey release is delayed into.. erm sometime in the future.
With that said, the game is supposedly available at www.retrousb.com sometime next week and the first 100 carts will retail at $28'ish. No worries though, the supplies are unlimited this time around.
