CPU Tests

blargg_nes_cpu_test5	Similar to cpu_timing_test6 (an older or newer revision?)
branch_timing_tests	These ROMs test timing of the branch instruction, including edge cases
cli_latency	This ROM tests the CLI and related instructions' delay in taking effect, and related IRQ behavior.
cpu_dummy_reads	Tests the CPU's dummy reads
cpu_dummy_writes	Tests the CPU's dummy writes
cpu_exec_space	Verifies that the CPU can execute code from any possible memory location, even if that is mapped as I/O space
cpu_flag_concurrency	(Not sure about this one - need to find the thread where it was posted)
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	This program tests instruction timing for all official and unofficial NES 6502 instructions except the 8 branch instructions (Bxx) and the 12 halt instructions (HLT)
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	fairly thoroughly tests CPU operation. This is the best test to start with when getting a CPU emulator working for the first time. Start execution at $C000 and compare execution with a log from Nintendulator, an emulator whose CPU is known to work correctly (apart from some details of the power-up state).

PPU Tests

blargg_ppu_tests_2005.09.15b	Miscellaneous PPU tests (palette ram, sprite ram, etc.)
full_palette	Displays the full palette with all emphasis states, demonstrates direct PPU color control
nmi_sync	Verifies NMI timing by creating a specific pattern on the screen (NTSC & PAL versions)
oam_read	Tests OAM reading ($2004), being sure it reads the byte from OAM at the current address in $2003.
oam_stress	Thoroughly tests OAM address ($2003) and read/write ($2004)
ppu_open_bus	Tests behavior when reading from open-bus PPU bits/registers
ppu_read_buffer	Mammoth test pack tests many aspects of the NES system, mostly centering around the PPU $2007 read buffer
ppu_sprite_hit	Tests sprite 0 hit behavior and timing
ppu_sprite_overflow	Tests sprite overflow behavior and timing
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	Displays a test screen that will contain glitches if certain portions of the emulation are not perfect.
sprite_hit_tests_2005.10.05	Generally the same as ppu_sprite_hit (older revision of the tests - ppu_sprite_hit is most likely better)
sprite_overflow_tests	Generally the same as ppu_sprite_overflow (older revision of the tests - ppu_sprite_overflow is most likely better)
sprdma_and_dmc_dma	Tests the cycle stealing behavior of the DMC DMA while running Sprite DMAs
tvpassfail	NTSC color and NTSC/PAL pixel aspect ratio test ROM
vbl_nmi_timing	Generally the same as ppu_vbl_nmi (older revision of the tests - ppu_vbl_nmi is most likely better)

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_phase_reset	Tests the correct square channel behavior when writing to $4003/4007 (reset the duty cycle sequencers but not the clock dividers)
apu_reset	Tests initial APU state at power, and the effect of reset.
apu_sweep	Tests the sweep unit's add, subtract, overflow cutoff, and minimum period behaviors.
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.

Mapper-specific Tests

31_test	Tests for mapper 31 (with various NES 2.0 headers for PRG ROM sizes)
BNTest	Tests how many PRG banks are reachable in BxROM and AxROM.
bxrom_512k_test	Similar to the BxROM test in BNTest above.
exram	MMC5 exram test
fme7acktest-r1	Checks some IRQ acknowledgment behiaviors of Sunsoft FME-7 that emulators were getting wrong in 2015. (by tepples)
fme7ramtest-r1	Checks how much work ram the Sunsoft FME-7 can access
Holy Diver Batman	Detects over a dozen mappers and verifies that all PRG ROM and CHR ROM banks are reachable, that PRG RAM and CHR RAM can be written and read back without error, and that nametable mirroring, IRQ, and WRAM protection work. (by tepples)
MMC1_A12	(Not sure?)
mmc3bigchrram	MMC3 test for large 32kb CHR RAM with NES 2.0 headers
mmc3_irq_tests mmc3_test	Three different revisions of the same MMC3 scanline counter and IRQ generation tests.
serom	Tests the constraints of SEROM / SHROM / SH1ROM variations of the MMC1 boards.
Submapper Tests	2_test - Mapper 2, Submappers 0, 1 and 2
	3_test - Mapper 3, Submappers 0, 1 and 2
	7_test - Mapper 7, Submappers 0, 1 and 2
	34_test - Mapper 34, Submappers 1 and 2
test28	Tests for mapper 28
vrc6test	VRC6 mirroring tests

Input Tests

allpads	Multiple controller test supporting NES controller, Super NES controller, Famicom microphone, Four Score, Zapper, NES Arkanoid controller, and Super NES Mouse
dma_sync_test_v2	Tests DMC DMA read corruption
mousetest	Test for a Super Famicom mouse wired in a Famicom expansion port as controller 3
PaddleTest3	Test for the Arkanoid controller
read_joy3	Various NES controllers tests, including read corruption due to DMC DMA

spadtest-nes	Super Nintendo controller test (when connected to a NES)
vaus_test	Another test for the Arkanoid controller

Misc Tests
