10/05/2015 Subject: SH4 Playable Ship Experiment Results
After removing all mods (with JSGME) I installed the PT-109 playable ship mod. It worked on SH4 1.4 and SH 1.5. I was able to pilot the ship and sink a few Junks. Question:-> How does one fire the torpedo's on the PT boat?
I then added the Battleship Yamato playable ship and a fix for it's AA Guns, but I did not see any Yamato. Then I checked the file folders and found that I had not completely unwrapped it's folder. I unwrapped that extra folder and got it to work for SH4 !.5. I'm gonna have quite a lot of fun with this ship. the question here is: How does one aim the main guns. all I could manage to do was use the red crosshair but I sank 4 ships anyway.
I then found severl folders even some single mission files that were not unwrapped properly so I corrected this and put them in the data/single missions folder.
Conclusion: I must take full responsibility for the install mistakes. And with a bit more practice with these SH4 and SH5 mods I hope to save myself from any more frustration.
Thank's Again for all the support....... TDD&BKidd
