As with all the 16-bit Sonic games, the [[PAL]] version runs slower than the [[NTSC]] version. However, the in-game timer is slowed down by the same amount, so identical times are possible in both versions. PAL players may have a slight advantage due to the slowdown aiding players' reactions, but in general players in all regions can compete equally.

Sonic Jam includes three different modes of playing the game: '''Normal''', '''Easy''' and '''Original'''. The Normal and Easy settings make small changes to the levels, such as additional rings (particularly noticable in the [[Death Egg Zone (Sonic the Hedgehog 2)|Death Egg Zone]], which originally featured no rings). It also features a [[Time Attack]] mode, which tracks times, but uses the same altered level layouts as the Normal difficulty. Players using Sonic Jam should therefore use the '''Original''' setting; identical to the original release of the game.
