Card list (MSU1)


Generally every card should work with sd2snes.
However some cards, while sporting fast transfer rates, have long access times (jumping between two non-consecutive sectors on the card).
This can impact MSU1 performance when using the MSU1 audio and data features simultaneously only, as two files have to be streamed at the same time.

Generally peak access times (T_max in the table below) up to 1 ms are acceptable for MSU1. I’ve come across cards with maximum access times as long as 9 ms. If the peak access time is slightly above 1 ms, low average access times (T_avg in the table below) can make up for it sometimes.

Note that cards with long access times can still be suitable for low-bandwidth and smaller transfers per frame. Also, using only the data or the audio extension at a given time increases tolerance.

As a rule of thumb the acceptable peak access time is 10 ms for audio only, 2 ms for data only.

On this page cards tested with sd2snes will be listed, including their measured peak+average access time, brand, maker/product code, revision, and serial number, and if MSU1 audio+video playback at full bandwidth is possible.

    A “Short” SD card adapter for use with MicroSD cards.

    This might get flagged as SPAM, but it could be useful.


    Is it possible, that a card works in ED64 but not in sd2snes?
    It’s a 64 GB ADATA SDHC Class 10 – always telling me, menu.bin was not found. But I just copied everything from the 4 GB Card I used before.


      Make sure the 64GB card is FAT32 formatted, NOT exFAT. Windows cannot do this out of the box I think, you will need a special formatting tool. If the card is already FAT32 formatted, it should work…


    So what 32GB SDHC card shall i buy, any recommendations please?

    Thanks! :)

    Best regards

    SD acc time 0,569/0.772 ms

    Both working


    As the MSU1 library seems to keep on growing lately, this one should be a darn good find!
    Brand: SANDISK
    Name: Ultra microSDXC UHS-1
    Size: 128GB
    T_avg: 0.45ms
    T_max: 0.51ms
    MSU1 ok: yes


    Been studying some specs lately (SD Association,

    It seems that the new label called “Application Performance Class” refers to minimum random read/write IOPS, which is exactly what we are looking for (well at least it’s a good rule of thumb).

    A1: minimum 1500 IOPS read, 500 IOPS write
    A2: minimum 4000 IOPS read, 2000 IOPS write

    The above mentioned SANDISK Ultra microSDXC UHS1 is an A1 class SD card and it looks like it passed the test. So try to look for these labels as they suggest minimum random access performance.

    And btw: Thank you very much ikari for taking the time and effort to provide us with firmware for the wonderful SD2SNES. Echt eine supertolle Sache! Ich lese mich gerade etwas in ASM-Programmierung bezüglich MSU-1 oder generell gesagt SNES ein, habe eines Tages vor einige der MSU-1 Patches für NTSC Spiele für PAL Versionen zu “porten”.


      Very insightful, thanks! Sorry I was slow to approve this comment, I’ve been down with a fever for the last days.
      Danke und viel Erfolg bei deinen Projekten! :)


    Alrighty then, i tested SANDISK Ultra microSDXC UHS1 A1 with 16, 32, 64 GB’s. Here’s a short list.
    avg. access times (ms):
    16GB -> 0.184
    32GB -> 0.192
    64GB -> 0.188
    max. access times (ms):
    16GB -> 0.734
    32GB -> 0.821
    64GB -> 0.788


      Wow this might be what we really need to look at. I’m trying to find a 128 gb or larger with A2 or A1 and UHS3, class 10 card although not sure if the UHS helps in this case. Anymore info on these findings would be very helpful.


    Thanks for the posts guys, you helped me pick out a card. How did you guys go about testing the avg. access times and max. access times? Is there a test I can load onto the SD2SNES or is it done with the SD2SNES diagnostic firmware?


    Here is a page that explains what to use to obtain benchmark information:


      Actually just go to System Information in the main menu (X button) and it will measure and display access times of the inserted card.
