That's a bug - a missing command in RPGmaker to fade the screen back in. If you can open the javascript console you can manually emit the command to fade back in:
Game_Interpreter.prototype.command222()Both F8 and F12 don't seem to work, I can't open the devtools. I'll try to see if I can find any way to enable it.
That map actually isn't implemented yet. 0.70 version has a lot of issues because the dev forgot to block off incomplete content which leads to the errors and black screens and all the versions after 0.70 mostly just block off that stuff.
I'll leave links to 0.70 here (just in case):
Some event from 0.70 are blocked from 0.74 so to avoid that is better replay.
Ohhh! So what about this "something bad will happen" thing after you borrow it? It got me curious because if it does come back in full game it would be tedious(?) to farm money and gave it back since it would be a long time
You can use RpgMakerSaveEdit or a online editor to edit the value.
Because MakotoYuki used a save editor. I'd imagine that the content is out of reach via normal means.
I recall it being available in 0.70. From memory, you needed fruit active and had to had sex with your sister at least once. Afterwards it became available at night when you're forced back to your room and your sister moves to her room. I can't remember if black screened or not but I'd imagine it did like how a lot of the castle scenes would glitch making the game unplayable. As a note, there's also a sleep together with the sister option without the fruit with no sex. Only difference I noticed is you wake up in her room instead of your own bed the next day.
I haven't seen it in game yet, but the assets are all there. I might assemble a gif or two in Krita if I feel like it.
