Gameboy Color freeze (or any other console): Visual effects
« on: November 11, 2015, 02:23:56 pm »
So with all this stuff in the glitches section about the game locking up, freezing, crashing or whatever you want to call it... do we actually know what happens when the game/a gameboy color freezes, in terms of the graphics? Are the lines specfic to each gameboy, each game, or do they vary dependant on the situation? I'm thinking about making a game sometime soon based around hacking the game itself, and I'd like some context as to what crashes look like on different platforms, so I've got something (moderately) relevant to base the art style on.

I took a quick look around the site and couldn't find anything, and whenever I type "crash" and "gameboy" into Google half the results are Crash Bandicoot games :/ Any takers?

Also I've got some research on the way (been preparing my Red save for a bit of glitching) so I'm not just sapping off of everyone's knowledge for nothing^-^

If no-one's done stuff like this (which I would assume they have) I'll gladly have a look.
Pixel Professor Oak is a spitting image of my physics teacher. Lab coat and all.

Proudly glitching on console, just pop me a message if you want me to do any research.

I know this is a necrobump, but relevant info included below.

If you crash with lines, beeping occurs, and the LCD messes up from time to time, it's launching crash data from the LCD. It has a length of 4-8 bytes, and 2 bytes are fired out whenever a beep occurs. Thedata repeats until power is turned off.
If the lines have a color laid out like the in-battle HUD, the battle script was executed. If not, the overworld/menu script was executed.
