Wait, really? I thought only another |

Maybe it needs clarification. If the screen was frozen by clearing LCDC, it will be unfrozen when its bit 7 is set. |

Ah, I see: it's another freezing mechanism, separate from |

Yes. Enlightened by beware. |

Then I'd like to suggest the following wording:
| SGB freezes/unfreezes the Game Boy screen automatically whenever the LCD is | ||
| turned off/on. |

| The screen retains its last frame when the "LCD" is [turned off](<#LCDC.7 — LCD enable>), though it gets blanked out after a while. |

I think "stops updating" might confuse people, although it's technically correct.
I'm not sure what "gets blanked out after a while" means.

AFAIK, leaving the screen turned off for a significant period of time causes the SGB firmware to blank out the framebuffer.

I think there's a lot of detail that could be discovered through hardware research. Personally, I'd prefer to hold off on edits that go from saying something that's unconfirmed and maybe half correct to something else that's that's unconfirmed and maybe half correct. Especially when it comes to the SGB which is a device that both most people don't have access to, and isn't emulated 100% accurately, even in low level emulators that emulate the SNES portion of the equation.

Do I need to call Cubby 🐻️ again for a test of how long it takes SGB to discard the last frame after LCD off?

Well, then following Nitro's logic, we should not include the original claim at all either?

I don't see where "it gets blanked out after a while" came from. Cubby didn't know either 🐻️
I wrote a test ROM that displays an image, turns off LCD while the A Button is held, and turns LCD back on once the A Button is released. DMG and GBC hid the image while A is held. NTSC SGB1 retained the image for my entire patience (about 20 seconds) and showed a little blip at the bottom of the play area indicating that the ICD2 was once again receiving signal from LCD out.

Can we safely remove the "gets blanked out after a while" bit?
