redcode / 6502 Goto Github PK

The link to Z in the README.md file is not useful, it just leads to a page that says 'Coming Soon...'. A better link would be https://github.com/redcode/Z I think.

Hi, I'm making a emulator for my hobby computer using the 6502 CPU. I'm using this library for my emulator CPU emulation. The only thing is, I don't know how to use this. Do I need to power the CPU on and then run the CPU with specified cycles?

ASL, INC and possibly other read/write instructions do two writes on an original 6502.
They first write the original value, then the modified one.
The CMOS 65C02 behave differently.

That can cause issues when working on memory mapped I/O, such as what is done on the C64.

Forgive me, I am completely new to C & C++. I am looking for a C library that can "play" (output waveform samples") for NSF and NSFe audio files. I have found a project game-music-emu which contains support for many different types of 8 & 16 emulators but it is written in C++ and I have a need to use C only code due to the development environment for my project.

Would this be a good candidate?

Please consider changing the license to something more compatible with a library, such as the LGPL or MIT/BSD. This would allow static linkage and easier inclusion in projects that are more permissively licensed.

Installed the Z headerless library as instructed. When building this project, however, it is looking for the file Z/hardware/CPU/architecture/6502.h:

$ make config=release-dynamic all

The directory architecture and the files inside there don't exist under CPU:

$ ls /usr/local/include/Z/hardware/CPU/
6502.h  Z80.h

Did I miss something during Z installation?
