I thought that I had a slow FPGA at first because the WODE would always get stuck on the loading screen with firmware above 1.28 but it turned out to be the regulator that I was using for 3.3v. Once I replaced the regulator for a better one or took 3.3v from the drive board firmware above 1.28 worked fine. I now use the latest firmware v2.9 or anything above 1.28 works just as well for me due to the fact that now for some strange reason any firmware below 1.28 will not read any ISOs
It's been a while since I added the WODE to that Game Cube so my memory is not very good. I think that I will read through this thread again to see if I can jog my memory a bit but off the top of my head:
I can't remember any settings on the WODE affecting audio streaming and the drive was directly connected to the WODE apart from power and gnd. Those extra wires coming from the drive board on the picture further up this page were power, gnd and eject for the slave board.
The only thing that I can think of at the moment is to try lowering the pot. Audio streaming games seem to be a lot more demanding on the drive and laser and I found that I had to lower the pot significantly with the drive connected through the WODE, especially for backups.
