Magical Puzzle Popils is a puzzle platformer game developed for the NES, with ports for the Turbografx-16 and the Game Gear also being developed around the same time. In the end, however, only the Game Gear port was released, with the other two versions becoming lost media aside of gameplay footage shared by Jun Amanai (the game’s programmer for all versions) through his YouTube channel.

On December 17 2025, the Video Game History Foundation and Hidden Palace preserved and released a late prototype of the NES version of Magical Puzzle Popils. While this prototype is fully playable from start to end, unfortunately the EEPROM chip that contained the sequence data for the music and sound effects could not be found, which means that the game no longer has any audio to play at all. Despite this, however, a lot of important sound-related data (sound driver, ADSR envelopes, ROM pointers, channel assignations) is still present in the other EEPROM chips.

This hack inserts recreations of all publicly available music tracks and sound effects into the prototype. This was done by porting the sequence data of all sounds found in the Game Gear version, along with doing many adjustments (ASDR, vibrato and note transposing edits) to match the audio heard in Jun Amanai’s gameplay videos as closely as possible.

This hack is compatible with both the prototype’s original release and NewRisingSun’s MMC3 conversion hack.
