Revelations: Persona for PS1 was included in the Playstation Classic Mini Console bundled with 20 games.
When the game was localized in the West, the overall difficulty was reduced by lowering the enemy encounter rate and increasing the EXP gained from battles. However, while experience gain was increased to an amount proportional to the decreased random battle rate, money drops were left the same, resulting in a potential shortage of cash.
The Snow Queen Quest was removed in the western version of the game, only allowing the player to commit to the SEBEC chapter. The data is still present in the game disk and it's possible to forcibly activate the quest by making use of cheating codes, but the vast majority of the Quest is untranslated and the game's engine cannot render Japanese characters which show as strange symbols.
