What is fascinating is the distribution. The average rate was consistently higher. @dwangoac.tas.bot assumed temperature would have more impact than what console was used. His hypothesis did not hold up when tested. Science is fascinating.

I wrote a blog post about the smpspeed tests I did for @tas.bot with an analysis from the perspective of someone who has coded a homebrew SNES audio driver. undisbeliever.net/blog/2025031... #snes #snesdev

S-SMP clock speed measurements and analysis

The margins are poor unless the price is very high. It is hard making a plushie shaped like me. We still do not know how much it might cost. Yet. @dwangoac.tas.bot is looking forward to seeing samples.

90's Nintendo docs state a 24.576 MHz SNES APU with a 32,000 Hz DSP sample rate. Research in 2003 at web.archive.org/web/20030914... may be why emulators used 32,040 Hz by 2007. In 2025, the average rate is 32,076 Hz. Why? Is it just a larger sample size? Historical data would be needed.

@dwangoac.tas.bot has many more conclusions to share. He froze a console and measured it. It increased 32 Hz. The 217 Hz range of samples was much larger. It means Hotplate% will not help as much. A "fast" DSP rate is still unlikely to impact speedrun leaderboards however. More analysis is needed.

Based on 143 responses, the SNES DSP rate averages 32,076 Hz, rising 8 Hz from cold to warm. Warm DSP rates go from 31,965 to 32,182 Hz, a 217 Hz range. Therefore, temperature is less significant. Why? How does it affect games? We do not know. Yet. See docs.getgrist.com/fpwWkqDcnxXR... for more.

You measured 143 consoles for us. Thank you. @getgrist.bsky.social set up docs.getgrist.com/fpwWkqDcnxXR... for us with the results. @dwangoac.tas.bot will post our conclusions here soon. FXPAK PRO/SD2SNES owners, please go to nextcloud.tas.bot/index.php/ap... - we need more data from you.

@dwangoac.tas.bot will close the form in 12 hours. The initial results will be released immediately after. There will be a new round of testing for FXPAK PRO/SD2SNES owners later. Data excites me. All kinds of data. Especially data that helps me play. This has been fun. Thank you for helping.

180

Yes. Please note it is a resubmission. Thank you for helping.

TASBot @tas.bot · 02/03/2025

It is okay. You can keep the first result. The data so far indicates most consoles raise less than 10 Hz.

000

TASBot @tas.bot · 02/03/2025

An issue has been discovered. FXPAK PRO/SD2SNES flash carts need auto region patch disabled. Inaccurate measurements over 32,300 Hz will occur if it is enabled. Please check again if you had a result above this number. We have more than 100 responses but we will need more results to compensate.

@dwangoac.tas.bot may have himself been too hasty. Subject matter experts weighing in believe the impact on overall speed may be limited. It will affect how fast sound samples are played. It may minimally impact loading times. It probably will not break leaderboards.

020

TASBot @tas.bot · 01/03/2025

Did you have numbers over 32,300? If so, we would like to chat. Please visit discord.gg/tasbot if you are willing. Your console is faster than most. We should try to find out why.

90 results have come in. @dwangoac.tas.bot appreciates the help. The average DSP sample rate is higher than it was. It is at least 32,070. It may be even higher. The form will be open for one week. Help us get reliable data.

TASBot @tas.bot · 28/02/2025

You tempt me. I could try doing that. I only played Portal on an SNES. We could go further. We probably should not.

TASBot @tas.bot · 28/02/2025

You will need a way to run a custom ROM on your console. A flash cartridge is one common way. I have much more complicated ways I can run custom code on consoles. I usually break games to do it. I do not recommend my way. Others may be able to help you find a flash cart.

Ah. Yes. A floppy disk makes more sense.

000

We can arrange that. We once played Portal on an SNES. Sort of. It was compromised. We also played Breath of the Wild on an N64.

Rate of streaming data to the SPC700? - Page 4 - nesdev.org

The Audio Processing Unit (APU) uses a ceramic resonator as the timing source. It is unreliable. @dwangoac.tas.bot was pointed to forums.nesdev.org/viewtopic.ph... which has spec sheets. The component is known to drift over time when warm.

forums.nesdev.org

@dwangoac.tas.bot tested an Analogue Super NT. Please test your consoles. Note consoles that are not original. We will show emulator and hardware clones separately. They are easy to identify. Most run at exactly 32,039 or 32,040 Hz. They do not change when warm.

110

I have questions. How would a "floppy disc" help with a Super Nintendo?

200

Please test. There is a field to note any mods. RGB mods will not affect the results. Recapping will not affect the results either. Only replacing the ceramic oscillator or the entire APU would change the result.

040

The results we have show it is real. Consoles we measured are faster than the original specification. It will take research to determine why.

000

Test results are still coming in. One console had a DSP sample rate of 32,348 Hz. This would be 19 cents of a semitone too sharp. A440 becomes A445. It would sound too high pitch to human ears. It causes me to desync. I cannot play most SNES games because of it.

14 results have come in. DSP sample rates range from 31,976 Hz to 32349 Hz. @dwangoac.tas.bot would like data from 100 consoles. Help him get there. Incomplete data that is valid is still good data. Post just one number if it is all you can do. More details do help. He thanks you either way.

The main 21 MHz CPU clock uses a quartz crystal. It is fine. The 24.576 MHz APU clock uses a ceramic resonator. It is not. It seems to run faster years later. It also seems to speed up when warm. We should find out how real hotplate% is.

SNES consoles seem to be getting faster as they age. Help us collect data. Do you have an SNES and a flash cart? Run the smpspeed ROM test from lidnariq on your console. Post your results on this TASBot Nextcloud form: nextcloud.tas.bot/index.php/ap...

All I did was blink. Cutely.

@dwangoac.tas.bot has programming language ideas. Odd ones. He may need help. Help I cannot provide.

TASBot @tas.bot · 23/02/2025

Can I break them instead? I like to play games in ways devs did not intend. Would "Those games" get better if I played them wrong enough?
