Though I'm certain a raycasting engine such as that is very possible to do on the NES I believe that one is fake unfortunately. The hand with the gun is 3 colors, so when it overlaps both the green and the blue it's 5 colors. So the hand and gun cannot be rendered using background tiles but would ha...

Because this is pure bullshit.

My guess is that Nintendulator is single threaded, and thus can only use one cpu core.

The thing is that Nintendo-made carts will end if everyone makes use of them, so it's more than healthy to find a renewable source. The number of carts produced today is nowhere near comparable to the numbers made back in the day. So if we reuse 1/1000 (or whatever the numbers might be) of the old ...

Please consider avoiding using "donor" carts because it involves destroying original NES games. Hahaha. Yeah, because there is a real shortage of NES games. :) Really, most NES games have probably already been destroyed, reusing some for you own stuff is hardly blasphemy. Most NES games aren't very...

I'd like to see a second background layer with independent scrolling. I imagine the fpga would have to count reads from chr-rom to know which pixel is being rendered, and serve pixels from the second layer instead of the real pixel if the normal background layer is transparent or something along tho...

Topic: indexing a constant (immediate)
Replies: 17
Views: 6972

The argument to an opcode is normally a constant memory address. Even if you use some named identifier for a memory address in your assembly code the assembler will translate it to a constant address. However, some opcodes take what is called an immediate address, which is not really an address at a...

There really is no need to keep 13 bits around that are just going to be shifted away since only the most significant bit that's shifted out matters for correct rounding. It's only in some rare cases where that bit is already rounded it might be off by one, and that is only in the second octave (the...

So to get the most possible precision using the "one octave table and shift" method I would have to do the following. Generate a LUT for the lowest octave (octave 0) using 1662607/(f*16) where f is the frequecy of the notes. And then the following in the playback code. get period from LUT divide per...

The .byte assembler directive is used to put data in the output generated by the assembly. Since the zp segment in that piece of code is supposed to go in RAM. Stuff will break when you put .byte in there. I haven't used p65 or read the tutorial though, so I can't give you much detail, but if you wa...

I have a dynamic sprite drawing routine, which takes the coordinates of an object (could be an enemy, a bullet, or basically any entity that requires sprites to be displayed), and it draws all of the enemy's sprites based off of that set of coordinates. First it draws all objects in first to last o...
