VFEMU is an interesting machine emulator framework.
Unlike QEMU etc., VFEMU simulates at a lower level, which means that it can simulate a module (e.g. CPU, RAM, Disk, Monitor, etc.) as well as its ports/pins, and how the ports/pins are connected.
It's somewhere between pure VM level and circuit level.
VFEMU might not be very fast, but we have more freedom.
Its API is not complicated. You can easily design your module and connect existing modules in your favorite way.
Anyone can make their virtual computer and gadgets here!
Go to the root directory of this project, and then do
mkdir build
cd build/
cmake ..
makeAnd then you can run examples in this way
./examples/demo_tst001Please see the files in example/.
We recommend that you start from demo_tst001.cpp,
which is a small example of how to connect a custom CPU
and custom RAM to form a small computer.
If you think it's simple enough, then you can try my custom NES Game Emulator demo_tnes01.cpp.
This is a good demonstration of the VFEMU framework.
Currently, we can boot many Mapper-0 games to their title screens and even demo screens.
It now has a basic implementation of the 6502 instruction set, an SDL2-based graphics output.
