I have a Railking F3 that I believe is from the RTR 30-4187-1 set.
It is a PS2.0 engine. The default sound file that is supposed to be on it is: s07rpf3___f3___sfe070501afin.mth
I'm not sure what the current sound file was on it, so I downloaded it off the engine and saved it.
I tried to load a different sound file on it, and the consumer loader gave me errors that I couldn't load a 3V sound file on a 5V engine. However, after looking at the above file that was supposed to be on it, I thought it was a 3V processor. The loader screen gave a critical error - 3V file on 5V engine. I tried a bunch of files. Same error. Got other errors that made sense - when I tried to load a PS3 file with 2Mb and it only had a 1Mb limit, but they were 3V files, too.
Then found r031pp5rksf3___sf_031017bfin.
I tried this, and it took, with no errors, but now my sound is gone. Engine worked in forward and reverse, but no sounds.
I went back to the old file that I saved off - it loaded, but now no sounds again! WHAT? It was working fine with that file!
Then hunted around the MTH website for any older SF engine, and found 20-2565-1. File name is:
p052pf3_ft_aba_all051011afin.
It WORKED! I had sound back!!!! But 2 hours ago, I got a warning that the engine needed a 5V file?
What's going on and why?
Is there a freight (and passenger) F3 that is supposed to work? I did not go back and try a different 3V, now that the engine has "accepted" the 3V.
Thanks, Dave
