Does anyone still have downloaded DanMemo game data, emulator backups, or extracted assets?

Hi everyone, I’m working on a personal project to recreate parts of DanMachi: Memoria Freese as an offline game for my own use, and I’m looking for help finding preserved game data.

The project is still in the research and asset-collection stage. My initial goal is a small playable prototype with team selection, turn-based battles, and local save files. I’d like to expand it with more characters and story content as the available data allows. I don’t have a working offline version yet.

I already have the APK, additional installation components, and some character portraits, equipment icons, and element icons. However, I’m still missing much of the content downloaded separately by the game.

Does anyone still have any of the following?

• Game data from an installation that completed the full in-game download.
• An old emulator backup that still contains downloaded DanMemo content.
• Extracted character sprites, battle animations, enemies, backgrounds, or skill effects.
• Story scripts, dialogue, voice files, sound effects, or BGM.
• Character, skill, enemy, or stage data, or documentation explaining their formats.

Japanese or English version data would both be useful. Partial collections would also help—please mention the version, region, or approximate date if you know it.

I’m especially interested in downloaded content beyond the APK itself. If you know of an existing preservation project or archive, I’d appreciate a link or a pointer to its maintainers.

Please don’t share login credentials, account tokens, or personal information from backups. An inventory or screenshots of the asset folders would be a helpful starting point.

This is a personal, non-commercial fan project, unaffiliated with WFS or the rights holders. Thanks to anyone who has preserved material from the game and is willing to help!
