Top 15 reasons you can get a "black screen":
01) You cheated on your game, modified some file outside of the game, to make more money or more keys. Madalyn does not show up at the church!
02) You modded the game, and it is not compatible with the new update.
03) You use updates but you missed one. You need ALL the updates between your last played version and the latest update.
Let's say you last played version 46082, you will need update 48091 + update 51092 + update 54101.
04) You have a compressed version of the game and update with a normal version. Not going to work.
05) You are trying to play from a corrupted saved game.
06) You understand the mechanism of updating only the www folder/directory but you are distracted! you copied from your zip www but to your install of Treasure of Nadia and not to the subfolder/subdirectory www.
07) You think you can play the game only from the update. A barrel of laughs on this forum.
08) NLT did it - True story - he changed a file name but not the json file linked to it.
09) You do not match the minimum system requirements:
OS: Microsoft Windows 7 / 8 / 10 or Linux or MAC
Processor: Intel Pentium Dual-Core T4200 (2×2.0GHz) or AMD equivalent
Memory: 2 GB RAM
Graphics: NVIDIA GeForce 8800 (512MB)
DirectX: Version 9.0c
Storage: 2 GB available space
10) You have modified the NSFW filter to Turn ON Filter.
11) You have a very old driver for your graphic card.
12) You do not have the proper codecs - like 32 bits for a 64 bits install. Good ones are K-Lite or CCCP (Good old Soviet Union)
13) You downloaded the game from an exotic website in outer manchuria.
14) Your OS does not support your graphic card.
15) You've installed a version of the game that is too old for your save file (NLT on Discord)
16) You have a controller plugged in like a joystick or pedals. They have to be disconnected.(NLT on Discord)
17) You are unlucky and victim of a random gremlin inside your computer.
