The only problem is you have to use CAB1 emulation for 100 step control. 1.4 was supposed to let you use TMCC control, but it doesn't work here for either the Cruise Commander or Cruise Commander M equipped engines.
Is there real functionality advantages to upgrading to Legacy 1.4? I cannot seem to be able to get a list of new features or improvements available.Al B
Not really.
That non-working feature was the only reason I could see to upgrade to 1.4. I don't have a ZW-L, so the only other reason I know of for the upgrade doesn't apply to me.
The good news is, it didn't break anything.
