displayed prior to starting the level. The sound was modified slightly to adapt it to the more limited audio hardware. The graphics were brighter. The controls were modified slightly to make it possible to only perform a high jump when the run button was pressed, whereas it was possible in the arcade version to perform one simply by being in motion when the jump button was pressed. However, the most important aspect that differentiated it from its arcade counterpart was the addition of "areas". Wonder Boy for the Master System and Game Gear had nine areas; this included all seven areas from the arcade original plus two new areas created specifically for this version. The new areas featured unique level designs different than the rest of the game. These two areas were dubbed as the fourth area and eighth area in the game. This resulted in a modification on the numbering for the areas lifted from the arcade original (for example, what was the fourth area on the arcade version became the fifth area on the SMS/GG version). As with the arcade version, collecting all dolls in the game would reveal an extra "area" which, in this case, would be the tenth area. Home computers The license to produce the home computer versions of Wonder Boy was awarded to Activision, who produced versions of the game for the ZX Spectrum, Commodore 64 and Amstrad CPC in 1987. The game was true in spirit to the original, although the levels beyond level 4 differed to allow for the necessary multi-load system. The first round of each area was always a forest, the second an ocean, the third a cave and the fourth a forest at nighttime (the C64 had round 1 at night time and round 4 during the day). This was not the case in the console and arcade versions, in which the areas provided more variation (although based on these same four themes). The Amstrad CPC version contained the graphics used in the C64 conversion, but the sound from the Spectrum conversion. Some Spectrum versions were afflicted with a bug that prevented the game from preloading all four levels in 128K mode – the fourth level's graphics would not load correctly, and it would be impossible for the player to move before the game crashed and the computer rebooted within around three seconds. As a result, 128K owners were
