Hacking the My Arcade Contra Pocket Player - Part I

This write-up walks through a hands-on teardown of a Target-sourced Contra Pocket Player, identifying a Rockchip RK3128 SoC, 2Gbit DDR3, and a Winbond SPI NAND. The author documents probing the NAND, attempting in-circuit reads with a HydraBus (encountering unreliable results), then successfully dumping the NAND via Rockchip USB recovery (rkflashtool), confirming consistent dumps and uncovering a GUID partition table and embedded Contra/MAME ROM; a follow-up will analyze the NAND image and ROM swapping.
