Card list

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, 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.
