Hi, is it possible for the iCode Uno/Duo Plus to recognize Commodore 64 controllers with two buttons? These are not very common (they came out with the ill-fated Commodore 64GS game console) but there are quite a few games that make use of the extra button. The first fire button connects pins 6 and 8 as usual. The second fire button connects pin 9 (PotX) to pin 7 (+5V). It would be great if this could be recognized by your adapter. Thanks!

Sorry pin 9 and 5 are used for paddles and currently the firmware expects to only see paddles connected to those pins. there might be some way to programmatically accomplish this but it would require a firmware update. I will ad this to possible enhancement list to consider in the future.
