Inconsistencies

Considering the technology at the time, it's not surprising ToyPop has its fair share of inconsistencies.

In-Game
In the game, there are a few coloring errors. This makes sense since arcade game sprites could only be loaded using a very limited color pallet. For example, Pino's skin appears yellow in his sprite, while he has a more pale tone in cutscenes. This could possibly be because they were trying to portray his tan skin tone from the concept artwork.

Another example is Acha's hair being white in her undamaged sprite. Upon getting hurt however, her hair appears as blue.

Outside the game, there are still a few inconsistencies in promotional material.

In Namco Museum Vol 1, Pino appears with a darker skin tone in the opening cutscene. Along with Acha whose hair is a much darker shade of blue.
