Run 19 (Pokemon Prism)

Twitch Plays Pokémon Prism is the fourth run of Season 3 and 19th run overall of Twitch Plays Pokémon. It is a ROM hack and the sequel to Pokémon Brown. It will be debuting on TPP and the game will be released after the run has concluded. It commenced on October 9th 2016 at 21:00 UTC.

The protagonist is Cyan, the first female protagonist of Season 3, and her starter is Larvitar.

Due to the beta format of the game, several bugs are expected to happen. During the early hours at the start, a function added to counter odd collisions caused by doubling the FPS caused encounter rates to be rolled twice per turn. This led to a very high encounter rate for the first two hours of gameplay before a fix was implemented.

During portions of the game, a single party member is required to proceed. During these portions, it is possible to obtain guest party members. Should the only guest party member with health leave, then whenever a battle commences a glitched sprite was shown and the battle ended instantly. After the first occurrence, inputs were frozen while a fix was prepared.

Near the end of the third day, Cyan attempted to leave a Pokémon only area with a full party. This caused Flaaffy to be replaced by a hybrid clone of Fifi and Y4.
