okay guys i think i figured it out this is the true append which is an extension to the main game https://sukebei.nyaa.si/view/2512415 the reason why this append isn't 1.02 is because there is no update to this game, just that it requires the main game to BE at v1.02 hope that clears up any confusion cos i've been confused as shit for the longest time to apply the append to the main game, copy the www folder to the 001_ゲーム folder of the main game (the main game HAS to be 1.02 which you can get from the link above) and that's it this append is a chapter called マリスの結晶 the true 即ヌキの欠片 is a standalone file and doesn't need the main game because it's literally just the gallery, hence the title "即ヌキの欠片" (a piece of quick fap) lmao so it's basically an incomplete version of the main game without the gameplay at all
