The first speed up comes from using a harddrive file (hdf) connected to the virtual accelerator SCSI connection. Unzip all the files into the same folder as the winuae.exe file. To get the QEMU part working you, need a base qemu dll and several support files. In the past few days, a new, beta 16 build had become available.
There was a marginal increase with my laptop and definitely much closer to the real NextGen hardware, it still didn’t feel like we were there yet. While I did download and test it, I didn’t see a huge speed increase. Their first release with the PPC JIT code was 2900b15.
So, Toni (WinUAE developer), and Frode (FS-UAE developer), have collaborated to get QEMU’s PowerPC core code working.
