The Joyboard is simply a cool thing to have. I don't have any of the three or so games made to work with it, or even a C64 emulator... The pre-Commodore Amiga joysticks on the other hand are great and what I choose to use. Simple, small and responsive.
The errors on my disk sets are so consistent, I feel sure in retrospect I stupidly torched them all on one machine... probably a 2000 I was fighting with a while back.
If you have any version of AmigaForever, you should try to create your own new Amiga Workbench install floppy disks, as all the files required are on the CD. I can't remember if they are separated into directories for each of the individual floppy disks, like the Workbench disk, the Extras disk, etc., but with some work I think it could be done. It has been a long, long time since I looked at the file structure on an AmigaForever CD.
If you don't own any version of AmigaForever, you can buy it new, or find someone with an old version that will likely sell it cheap if they have upgraded to a later version.
