donation has been made - thanks a lot!!
it WAS the write protection that caused the issue, hopefully this will save some other people`s headaches...
two more questions:
with the amigasys3plusaga version that i somehow managed to put together my cd32 cd rom was recognized, now with amigasys4aga it just spins but nothing happens on the wb screen. how can i get this cd rom to work?
the second question, do i really not need this aux-datatype?
