WebOct 2, 2024 · The OP (and myself) want something to replace the PPU and/or CPU in an existing NES/Famicom system. So it still runs from cartridges and all of the original hardware. Basically, remove the CPU and/or PPU and replace it with this. Then from that point, extra features can be added such as RGB output and VT03 support, etc.
WebJul 23, 2024 · For example the PPU access the cartridge through the mapper in the memory controller to read drawing informations, the CPU writes to the PPU using address $2007, etc. Ending notes I will prepare more detailed posts about the NES architecture and emulation , even though there are still some concepts that are not clear to me and … WebScrolling. The scroll is one of the primary mechanisms to simulate movement in space in NES games. It's an old idea of moving the viewport against the static background to create an illusion of movement through space. The scroll is implemented on the PPU level and only affects the rendering of background tiles (those stored in nametables).
WebWe will create the PPU emulator using four main steps: Emulating Registers and NMI Interruption. Parsing and drawing tiles from CHR ROM. Rendering PPU state: Rendering background tiles. Rendering sprites. Implementing the scroll. The first step is very similar to emulating the CPU. After the third one it will be possible to play games with ... http://freem.github.io/nes_corelib/files2/ppu/rle-asm.html
