N64 guru, I have another good riddle for you. It’s really hard, as it’s not solved until now.
So, the task is clear: how to make the sky in Perfect Dark visible?
I’ve attached a part of Glide64 log, look at it. First, sky texture is loaded. I’m sure it’s the texture of the sky; I’ve checked it with Glide64 debugger. Then, combiner is set. Now interesting part – set of commands which suppose to be rdphalf commands, but they are surely not. I’m pretty sure that these commands are used to draw the sky, but I don’t understand how. rdp.cmd0 keeps no information besides command's index, so only rdp.cmd1 is important. It can’t be address in DRAM since it can take value of 0xffffffff. So what it could be? Could it be color? Yes, and the combiner uses shade. Could it be coordinates? Hmm, if it is some kind of texrect, may be.
What do you think?
