You'll be glad to hear it was because your computer is too fast ;) The floppy emulation was using a fixed number of cycles between generating interrupts and sending data to the ARM, but it seems that RISC OS relies on fixed amounts of time passing between the interrupts instead of fixed amounts of CPU cycles. So on a slow machine the floppy code worked fine, but on a fast machine it would fail horribly. I've changed the code to use timings that roughly mimic those of a real floppy drive, and that seems to have fixed the crashing for me. Let us know if you're still having problems! (CC'd the arcem-devel list instead of RPCEmu to keep things on-topic) Cheers, - Jeffrey ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 -- arcem-devel mailing list arcem-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/arcem-devel
