# puce65c02
puce65c02, a WDC 65c02 cpu emulator focusing on accuracy and performance
runs at ~1Ghz on a modern computer  
powers reinette IIe : https://github.com/ArthurFerreira2/reinetteIIe

### tests
I left the test and timing routines I used during developpement  
you can use them to verify accuracy :

Theses tests require `6502_functional_test.bin` and `65C02_extended_opcodes_test.bin` which you can get from https://github.com/Klaus2m5/6502_65C02_functional_tests  
and `timingtest-1.bin` I got from BigEd at http://forum.6502.org/viewtopic.php?f=8&t=3340

### compile and run :
```bash
g++ -Wall -O3 -D __TESTS__ puce65c02.cpp -o puce65c02 && ./puce65c02
```
or, much slower but with detailled info :

```bash
g++ -Wall -O3 -D __TESTS__ -D VERBOSE puce65c02.cpp -o puce65c02 && ./puce65c02
```
or, if you just want to check the cycle accuracy :

```bash
g++ -Wall -O3 -D __TESTS__ -D TIMING puce65c02.cpp -o puce65c02 && ./puce65c02
```
