|  Re: New emulator with Plus/4 support is developed
If you want to try out the latest version, I have now updated the ep128emu.exe.zip file. As usual, you still need the other files from the older full package, as well as the 1581 ROM if you want to use that. In the machine configuration, load the first 16 kilobytes to ROM 30, and the second 16 kilobytes to ROM 31. Then you can add D81 image(s) in the floppy configuration dialog (unit 8 is A, etc.; the geometry parameters are ignored, because a D81 is assumed to always have 80 cylinders, 2 sides, and 10 sectors per track). The image file may also be \\.\A: to access a disk directly - this may or may not work in practice.
A PRG file can be loaded on startup with the -prg command line option.
Note: some configuration parameters are now interpreted differently, so the speed of the emulated machine may not be correct if there is an old configuration file - set CPU frequency to 1 (this is a multiplier, not a Hz value), and video clock frequency to 17734475 (PAL) or 14318180 (NTSC).
