现在在哪能买到 Rev H 的版本?
这个东西没有一个固定的厂家来做?都是商家自己做的?因为开源?
现在最新的是 Rev H 吧?
我看这里 http://retrorgb.com/sd2snes.html 写的是这样
There are a few differences in the audio circuit of the SD2SNES revisions:
SD2SNES PCB Revisions A-F have slightly lower audio output.
SD2SNES PCB Revision G was a quick fix for this, boosting MSU-1 audio to the correct levels but introducing some noise.
SD2SNES PCB Revision H (and newer) adds an audio opamp forever fixing MSU-1 audio functionality.
