A Nes(FC) Emulator written based on Qt5

Description

This is a NES Emulator wrote with and ONLY WITH Qt5, no other thrid party headers/resources need to run.

• CPU
• PPU (referenced from OneLoneCoder's olcNES)
• APU (I used the Simple_APU implementation from Blargg's Nes_Snd_Emu, so there is no IRQ support for now)
• Cartridge
• Mapper 0/1/2/3/66 (Working with Mapper4, smb3 can run but others can't)
• Controller
• Debugger (You can only check the CPU Register and Memory for now...And Performance alert!!!)

How to Compile?

Easy peasy, classic three steps:

1. Install Qt v5.15.2 with MinGW 64-bit Compiler
2. Open QtCreator, choose the .pro file
3. Release Mode, Run!

User Guide

1. The Release version is for those who just want to play games. Packed with windeployqt on Windows

2. Start-ChooseFile, Select a .nes file and run! (You have to make sure the mapper your rom is using are already supported by the emulator)

3. Debugger-OpenDebugger, Open a window called debugger. You can check the Memory (Only the 2KB on Bus) and CPU registers. ALERT, you will see performance drop significantly after opening debugger.

4. Option-toggleSound. If you want to play silently (and to improve performance a little bit), use this.

5. Option-Save/Load。While you're running a game, Save will create a real time savefile, under path:./save/Game_title/TimeStamp.sav; click Load if you want to continue from a savefile

6. Control Mapping

   Controller No.	Up	Down	Left	Right	B	A	Select	Start
   Controller1	W	S	A	D	J	K	LShift	Space
   Controller2	Key_Up	Key_Down	Key_Left	Key_Right	Z	X	[	]
