There are emulators. Please don't derail this with a topic already being discussed on the forums.

Sorry. Didn't mean to derail the topic. I meant true emulators not converters and the other topic is for ones for PS Vita.

So how do you read the assembly code from the rom? I looked at the link at page 3 and I didn't see how to read the code.

[NUj6URfi]

Like from a cartridge and not .nes file unless that is what is on a cartridge.

[N36fSL3A]

What? A .nes file is a image of a cartridge.

You don't get assembler code, you get binary code. You read the opcodes and emulate how the 3 processors would work.

[NUj6URfi]

Okay, how do you read the binary code or opcode?

[N36fSL3A]

Seriously?

With fstream you load in the nes file. You then read the contents and a certain part of the cartridge and then you read an individual byte. In a massive switch statement you check what the code is and use the correct function for the opcode.

Look up .nes headers and how to use the standard ifstream & ofstream library.

[NUj6URfi]

Thank you. I did not understand you could just use fstream.

[N36fSL3A]

You can use fstream on all files...

I thought it was for text only. Thank you very much.
