CPU Tests
| branch_timing_tests | |
| cpu_dummy_reads | |
| cpu_dummy_writes | |
| cpu_exec_space | |
| cpu_interrupts_v2 | tests the behavior and timing of CPU in the presence of interrupts, both IRQ and NMI; see CPU interrupts. |
| cpu_reset | tests CPU registers just after power and changes during reset, and that RAM isn't changed during reset. |
| cpu_timing_test6 | |
| instr_misc | tests some miscellaneous aspects of instructions, including behavior when 16-bit address wraps around, and dummy reads. |
| instr_test_v5 | tests official and unofficial CPU instructions and lists which ones failed. It will work even if emulator has no PPU and only supports NROM, writing a copy of output to $6000 (see readme). This more thoroughly tests instructions, but can't help you figure out what's wrong beyond what instruction(s) are failing, so it's better for testing mature CPU emulators. |
| instr_timing | tests timing of all instructions, including unofficial ones, page-crossing, etc. |
| nestest |
PPU Tests
| blargg_ppu_tests_2005.09.15b | |
| full_palette | displays the full palette with all emphasis states, demonstrates direct PPU color control |
| nmi_sync | |
| oam_read | |
| oam_stress | |
| ppu_open_bus | |
| ppu_sprite_hit | |
| ppu_sprite_overflow | |
| ppu_vbl_nmi | tests the behavior and timing of the NTSC PPU's VBL flag, NMI enable, and NMI interrupt. Timing is tested to an accuracy of one PPU clock. |
| scanline | |
| sprite_hit_tests_2005.10.05 | |
| sprite_overflow_tests | |
| sprdma_and_dmc_dma | |
| tvpassfail | NTSC color and NTSC/PAL pixel aspect ratio test ROM |
| vbl_nmi_timing |
APU Tests
| apu_mixer | Verifies proper operation of the APU's sound channel mixer, including relative volumes of channels and non-linear mixing. recordings when run on NES are available for comparison, though the tests are made so that you don't really need these. |
| apu_reset | Tests initial APU state at power, and the effect of reset. |
| apu_sweep | Tests NES APU sweep cutoff (silence) thresholds and sweep subtract mode |
| apu_test | Tests many aspects of the APU that are visible to the CPU. Really obscure things are not tested here. |
| blargg_apu_2005.07.30 | Tests APU length counters, frame counter, IRQ, etc. |
| dmc_dma_during_read4 | Tests register read/write behavior while DMA is running |
| dmc_tests | ?? |
| dpcmletterbox | Tests accuracy of the DMC channel's IRQ |
| pal_apu_tests | PAL version of the blargg_apu_2005.07.30 tests |
| square_timer_div2 | tests the square timer's period |
| test_apu_2 | 11 tests that verify a number of behaviors with the APU (including the frame counter) |
| test_apu_env | tests the APU envelope for correctness. |
| test_apu_sweep | tests the sweep unit's add, subtract, overflow cutoff, and minimum period behaviors. |
| test_apu_timers | tests frequency timer of all 5 channels |
| test_tri_lin_ctr | tests triangle's linear counter and clocking by the frame counter |
| volume_tests | plays tones on all the APU's channels to show their relative volumes at various settings of $4011. Package includes a recording from an NES's audio output for comparison. |
