StepFC

Make FC(NES) Emulator Step by Step

Re: Simulation of red and white machines from scratch

Project description

Projects with VS2017 and CodeLite are also available to ensure successful compilation on different compilers.

License

• StepFC::StepX Each step, based on MIT, focuses on sharing code
• StepFC::StepFC Finished Emulator, based on GPLv2, focuses on executable binary files of the emulator itself

StepX List

0. Step 0: Load the NES ROM file
   • Reading files is preferred.
   • But laying a solid foundation is also very important, interface is a good thing
1. Step 1: Implement basic CPU read and write functions
   • You need to understand the layout of the CPU address space
2. Step 2: 6502 Compilation
   • Debugging is an indispensable part of decomposition
3. Step 3: Implement CPU instructions
   • This step is bigger than before
   • Implement all CPU instructions
4. Step 4: Background Rendering
   • Implement the first image display
5. Step 5: Basic Input
   • Implement standard dual handle input
6. Step 6: Sprite Rendering
   • Then it renders 64 elves
7. Step 7: Implementing Medium Precision Synchronization
   • Vertical synchronization based on primary violence
   • Merge background with elves
8. Step 8: Implementing Basic Audio Playback
   • Use a terminal state machine to implement audio
9. Step 9: Implement Mappper1234
   • Mapper4 is mainly introduced because it will trigger IRQ
10. Step A: Implement basic mixing
    • Increase audio accuracy from 60Hz to 44.1kHz
    • But the distance is still dozens of times smaller than 1.79MHz, and the road is still long
11. Step B: Standardize archive reading
    • Finally standardized storage files
    • SL Dafa is good
12. Step C: Video and playback
    • Can be used for TAS
13. Step D: Filters and Filters
    • Make the user experience better
    • FC even comes with its own filter
14. Step E: Extended Audio
    • Extended audio is also a highlight of FC
    • NSF Exploration
    • Audio visualization
15. Step F: All become F
    • Restart
    • Extended input
    • More precise simulation
    • FDS BIOS
    • More Mappers
    • Game specialization
    • Platform optimization
    • network
    • Graphical user interface
    • NES debugging
    • Cheater/Golden Finger
