There’s something amusingly contrary about TikiPod’s desire to take the most powerful handheld on the market, and force it to play games that appear to be running on decades-old hardware. Boot up PlayStation Mobile’s Rock Boshers DX and you’ll swear the London-based studio is trolling Vita owners, as a tape loading screech all too familiar to wrinkly Spectrum gamers slowly heralds the arrival of the title screen – and the chiming chiptune that follows recalls Jonathan Dunn’s classic Robocop theme. For veteran gamers, this is a powerful hit of nostalgia even before you’ve hit the start button.
