Thanks for the reply. Your avatar in the game did clearly warn me of messing up with the game, but I didn't take it seriously. :D I was time traveling a lot because I tried to win the lottery. Well, I guess I'll make a backup of the old save and start afresh. It's okay, I understand the risk involved with wantonly messing up with the settings.
I haven't encountered any bugs before using the computers, so I don't think you need to comb the code for now. I have the digital copy which I'm playing on a Super Famicom through SD2SNES flash cartridge. It has Super Game Boy functionality so I can play GB games on the TV. :D
What a cool way to play! I think my games made in the future with GB Studio 3.0 are going to have pretty nice SGB support. It's kind of somewhere in between an original Gameboy and a Gameboy Color. What palette are you using for the game?
I tried playing with gray scale palette with black borders, but the contrast between the different hues wasn't exactly what I wanted, so I ended up using the default palette which is white, lighter and darker orange, and dark blue.
I actually thought you had implemented some SGB features, because the first time I read Yoki's logs in Room 3 the GB border turned from gray to pink! I haven't managed to reproduce it, so it was definitely buggy. :D
Here's some screenshots, kinda hard to capture on a phone camera how good it actually looks:
(the border in these photos look like different hue due to how the camera works)
That's a great palette! I actually started the project in GB Studio 1.2 so I planned the game to have one palette throughout at first. It was similar. It was a white, a mustard, a desaturated purple, and black. I think the only major difference with the one you used is that it's more saturated.
