At the moment I can't tell as I don't have a working RiscPC at home. My checking that will have to wait until I can organise myself and take the software 'to work' and try it there. Probably some time next week. Alternatively, if you (or anyone else) is interested I can put !WAV_FFTScan up on the web for others to try out and compare RPCEmu with a real RiscPC. I'll also see if I can refind the IEEE routines I used to check in the past, and give that a go on RPCEmu. Has anyone already done that? At present I assume RPCEmu just used the default version of the FPE module that came with RO4.02. I'll check when I get a chance. Although as I said, the discrepency isn't enough to give me any problem or worry, just a curio.
