Boulder Dash EX is a remake or enhanced version of the classic Boulder Dash arcade game. The GBA port likely retains core gameplay of navigating underground levels, pushing boulders to crush enemies and reach the exit. This version updated the classic formula for the Game Boy Advance hardware. While the original Boulder Dash was developed by Peter Liepa, the GBA version's developer and publisher would need further verification.
