This isn't really an emulator somebody would play a game with.
Here's the list of features supported:
2.1. 6502 CPU (central processing unit)
Based on Marat Fayzullin
m6502 cpu emulator core. Completely rewritten to take advantage of C++
features such as inline functions and classes.
2.2. Memory mappers
Supported memory mappers: 0(none), 1(MMC1), 2(UNROM), 4(MMC4), 6, 7 and 15.
Some work better, some don't.
The key pads of both players are supported. However, the program doesn't
do any trick to force the keyboard to binary mode or scan code mode.
Therefore, it doesn't recognize simultaneous key presses. It always assumed
that the last pressed key is now down and nothing else.
It is possible to input the Dr Wily level 1 password in Mega Man 2 (I have done it),
but it isn't possible to finish the first level of Super Mario Bros.
2.4. PAPU (paraller auxiliary processing unit): Sound
Most of the time used in developing this emulator has gone into the sound
emulation. In Mega Man 2, Solstice and Solar Jetman, the sound emulation
quality is perfect, but in Super Mario Bros, it's pain to hear. I have
no clue what is the reason. The documentation available of the sound
circuits is no nearly good.
The sound emulation, due to it's exactness, is very time consuming.
It requires a fast computer.
The PCM emulation doesn't work. It just can't get it working.
It succesfully decodes DPCM encoded sound samples, but it does
not work in games such as Blades of Steel or Super Mario Bros 3.
Those games don't even startup.
2.5. PPU (picture processing unit)
This emulator doesn't use graphics. It's really a text mode NES emulator.
The PPU emulation is also very exact. It takes really good care of
the timings, but absolutely nothing is drawn.
It's nice to investigate how the NES works.
However I guess I dived too deep...
My goal was to make perfect sound emulation to record music.
After I realized that I could get
instead, I abandoned this project.
Nowadays I'm working with SNES games.
