Introduction
------------

ffnes is a nes emulator.

Now there are a lot of nes emulators, but for me, I still want to write a completely new one. It's an interesting thing.

I have already spent a lot of time on study how nes hardware working and how to write a emulator. Now I'm ready to write code and do debugging.

I payed more attention to the quality of the code and portability. I think the code is clear and good for your reading, enjoy it.


How to compile
--------------
There is a vs2005 project for win32. You need install vs2005, then goto ffnes/vs2005 directory open ffnes.sln, and press run button directly, everything will be OK.

If you are using ubuntu or other linux distribution, you need install a mingw32 gcc compiler, then you could goto src directory, try make.
The target binary is for win32 due to mingw32. Currently code can't compile for linux platform, need do more porting work.


How to use
----------

Keyboard definitions for joystick:

up - E
down - D
left - S
right - F
A - J
B - K
turbo A - U
turbo B - I
select - B
start - N
alt - hide/show menu
alt+enter - toggle fullscreen

getting source code:
git clone https://github.com/rockcarry/ffnes.git

Please provide an .exe file. Some users won't have the ability to compile a C++ program or won't download source code out of fear of viruses (no offense).

Won't download source code fearing viruses, but will download an executable?

Alright, sucky answer. But an .exe would be convenient for users and some people don't have C++ compilers. Its standard to provide an .exe.

I think it's just fear of entirely unnecessary effort.

Not providing a binary means every user has to do the work of building it, instead of just one person.

Or maybe it's fear of compilers? I think that's a justifiable fear.

Fry: Not sure if agreeing with me, or being sarcastically disagreeable.

[rainwarrior]

I'm not sure how you'd read any of it as sarcasm? The "fear of compilers" bit was a joke, but not sarcastic. They really are scary awful beasts. (Aaaa, sorry, yet another thread is off topic now isn't it.)

[Quietust]

On the topic of compilers, why Visual C++ 2005 and not a later version like 2010 or 2012?

It doesn't compile out of the box with VS 2013. Complains about not being able to build an MFC project with a non-Unicode character set. Switching to Unicode (from Multi-byte) results in a bunch of errors. I gave up at that point.

Sorry, I just wanted to make a Fry from Futurama meme and couldn't think of the 2nd line.

Now this is why I complained about a lack of .exe in the first place.

Incidentally, the usage of MFC also prevents it from being compiled with Visual C++ Express, which is probably a show stopper for quite a lot of people here. I'm assuming the reason it uses 2005 is because that's the only version rockcarry has.

That's why memes should be avoided here.

I could convert all that code into C and compile it... but is worth the effort? Looks like an old and dated emulator.

[rockcarry]

I am so sorry everyone, It's my fault. I will upload binary of ffnes.
The project is still under developing, so there are many bugs, and something didn't implemented. Due to this I'd like make it stable first, then release the binary.

yes, on my old winxp computer, only vs2005 can work.
