65c816 test rom
by on (#165152)
Hi all,

I have developed an 65c816 cpu core emulation using ARM.

I need to have some test code to verify the core works perfectly.

Do anyone knows where I can find some test roms / assembly code that can test a 65c816 ?

Thanks for any pointers.

Does its emulation mode (SEC XCE) run nestest correctly, at least until the part where the unofficial (and uninherited) instructions start? (Despite the name, it's a CPU test and has a mode with no dependency on the NES PPU.)

For the nestest.nes
My core pass all the test on the first page of normal instructions and address modes
For the second page of invalid opcodes, it hangs after issuing a beep.
