It doesn't: cpu_idle = 0 in rpc.cfg, even though the CPU is, clearly,
idling correctly! But several items in rpc.cfg bear no relation to
reality:
RPC.CFG REALITY
mouse_twobutton = 0 correct
network_type = off correct, though network is connected
via bridge
mouse_following = 1 correct
cdrom_type = 0 correct
cdrom_enabled = 1 not according to Configure*
refresh_rate = 60 correct by 'Settings'
stretch_mode = 1 ?
sound_enabled = 0 correct
vram_size = 2 correct
cpu_type = ARM610 S/ARM selected in 'Settings'
mem_size = 32 256MB selected in 'Settings'
ipaddress = 172.31.0.1 RPCEmu here = 192.168.2.2
cpu_idle = 0 enabled (and seems to be working)
(*just noticed that the RAM disc icon isn't on the icon bar, though it
is selected in Configure-Disks). It was there yesterday: I'll try
rebooting.
