The sixty502IntroductionWelcome! This is the home of project 'sixty502', a Nintendo Entertainment System(c) emulator written in Java 1.6. AuthorsChris Pable (pkgingo@google.com) Chris Erickson ... [More] (neoscriptor@google.com) GoalOur goal for this project is to successfully emulate the Rockwell 6502 processor contained inside the NES. This goal includes: Parsing 6502 assembly source code files. Translation of 6502 instructions into Java methods. Representing a physical memory using a data structure. Memory-mapped input/output. To be expanded upon.. DocumentationPlease see the Wiki section for a detailed look at our implementation. [Less]

This project is to recreate the 6502 microprocessor that will be pin and instruction set compatible with the MOS Technology 6502 in the Apple II series of computer, and will be drop in compatible with ... [More] that computer. The project consists of HDL for the CPU, written in SystemVerilog, an instruction level emulator for the CPU, a full regression and unit test suite, a random code tester and demonstration and example code. Eventually, the HDL design will be implemented in hardware. [Less]

SummaryA MOS Technology 6502 simulator and 2 pass assembler written in C# AimsAn almost complete 6502 simulator written in C#, it implements an almost complete instruction set along with a working ... [More] two-pass assembler. In the short term, the aim is to complete the instruction set and the user interface, so you can see the processor status, etc. In the slightly longer term, the aim is to implement save/load of assembled programs, a console for text-based I/O, alter the structure of the simulator to allow use of interrupts (and to implement them!) as well as generally improve the structure and flow of the simulator. HistoryI originally started writing this for something interesting and different to do, away from my day job as a Java developer and PhD student. I chose C# because I like both the language itself and because Visual Studio is one of the best IDEs I've used (and as a kind-of student, I got it for free =) Unfortunately, after a couple of months of on and off development, I had to take a break to actually finish my PhD and so I stopped working on this around December 2008. No I have time to start work again, the initial progress will probably be quite slow, due to the need to familiarise myself with the 6502 again and try and remember what I had in mind for the rest of the simulator. (The lack of comments in the code don't help...)
