![]() There are plenty more tests like this that could be written. Theoretically you could read the entire screen in terms of transparent/not transparent, though only one pixel per frame, so it'd take most of a day to do so. ![]() Interestingly, most aspects of the PPU can be verified by using sprite #0 hit. You can probably think of many: proper frequency of waveforms, DAC volume levels, DMC sample playing. Several aspects of the APU, like the triangle's length counter, aren't reflected in the status register. What other observation based NES tests are there? That is, tests where the ROM itself can't tell the difference between the real system and inaccurate emulation, but the user can easily observe the difference? Maybe some sound test? Maybe an input latency test? An example exists at the bottom of this page:Īnyway, that would get my vote for most creative test ROM for the NES There are tests for seeing if a human is color blind, where the person will see a "5" if they are not color blind and a "2" if they are color blind, even though it is the same static image. But would that be possible? For example, have both messages displayed on the screen, but each message is displayed in a different color pattern, so that under NTSC, "TV Colors Test: PASSED" was readable and "TV Colors Test: FAILED" was not readable.Ī similar thing has been done before. That would be a really cool test ROM if the image it displayed read "TV Colors Test: PASSED" under an NTSC display and "TV Colors Test: FAILED" on an emulator that only does RGB. Then you wouldn't be able to claim you pass all my tests unless you do NTSC too. It'd display images that you couldn't make out unless you have proper NTSC emulation. What's wrong? Why is it doing this? I'm not entirely well-versed in emulators/roms so please excuse me if there is some blatant, rookie mistake I am making.I should write a "TV colors" test which displays checkerboards of particular colors that will appear identical to another solid color on an NTSC TV, but not on an emulator that only does RGB. I went back to Nestopia and tried mapping all the controls to my keyboard and even that didn't work. ![]() I did the same thing with the emulator and tried out FCEUX instead and still nothing. I figured maybe it was a bad rom so I downloaded a different version and that didn't work either. dmg file, and I installed Pinnacle Gamer Profile. I ran joy.cpl on my computer and made sure the controller was set as preferred and was properly calibrated, I downloaded Emulator Enhancer but couldn't find anything on how to install it and didn't know what to do with the. I looked all over the Internet for a solution and tried many different things. I tested the keyboard too, just in case, and nothing. ![]() When I ran the rom, however, the controller wasn't working. ![]() I checked Machine > Input and it had Pad 1 selected, which is what I mapped under. From there, I set all of my controls and pressed okay. I realized my computer wasn't finished installing the drivers for it and once it was done, it showed up in the joystick column. When I went to map the controls through Options > Input, the controller wasn't showing up in the "Joysticks" column. I first plugged my Xbox One controller into the USB port on my computer. I just downloaded Nestopia today and have been trying to get the controls to work.
