 step up: find the fade out. see the game fades out when you go into a door. find where that code is, then see what gets called next. finding a fade out should be easy: look for when they reprogram the VGA palette registers to dim every color to black. 10 comments
OKAY realistically this is a game that features several different games you can play, and games between games. they're just gonna make each one a separate overlay. so I need to figure out how it shifts overlays and how to track which overlay is active looks like the separate game engines are called puzzler, electric, and simple. I love when games use __FILE__ in their assertions. please tell me all your filenames please oh sweet laser jesus I found the upload palette function and THEY UNROLLED IT why do: for(int i=0;i<256;i++){ when you can do upload_color(0,palette[0]); and just repeat 251 more times the worst part is that this was done with a compiler from 1991 so there's no way it unrolled the loop itself. they did this manually oh that's cute. their set_palette function takes two arguments: a pointer to the palette, and a number of extra palettes to apply. so they could set up an array of palettes in decreasing brightness, and just do set_palette(&fade_pallets[0], 64) to go through them. but the same function is a regular one-time set_palette if you just pass 1 for the second argument. "hey ghidra what calls set_palette?" "I don't know! you're in 16bit segmented mode! pointers are MEANINGLESS |

and all are in overlays. ugh.
