Re: Anyone have a IDE64 v3.1 or 3.4?
From what I have been able to tell, the IDE64 is ideal for using PRG files, not D64 images since there is no real 1541 emulation. The 1541 Ultimate is the ideal solution but, as you said, it is also the most expensive. I was able to use the uIEC to actually load and play D64 images that do not use a fast loader. Unfortunately, any software that loads programs into the 1541 in addition to the C64 will not work on anything but the 1541 Ultimate (from what I know).
If you want a fast, inexpensive way to get decent 1541 emulation then I would use the uIEC or XA1541. If you want excellent compatibility then the 1541 Ultimate is the way to go.
