mos6502-test-runner

Test harness for testing mos6502-emu against TomHarte's 6502 tests.

This test harness skips all tests for illegal KIL opcodes but runs all others.

mos6502-emu currently passes all official opcode tests but fails on some of the illegal opcodes:

• $6B (ARR)
  • Works correctly for NES 6502 but not stock 6502
• $8B (XAA)
• $93 (SHA)
• $9B (TAS)
• $9C (SHY)
• $9E (SHX)
• $9F (SHA)
• $AB (LXA)

To run tests using stock 6502 behavior (decimal flag works):

cargo run --release --bin mos6502-test-runner -- -d ../ProcessorTests/6502/v1

To run tests using NES 6502 behavior (decimal flag does nothing):

cargo run --release --bin mos6502-test-runner -- -d ../ProcessorTests/nes6502/v1 --nes
