Thanks for your help. I finally got it last night . Since I could never get past the first part with full power, I wound up doing it with Max's VF. I used Minmay as support. For the first part, I held down thrust and missiles the whole time (which occasionally led to Minmay singing) and just went after them hard. I eventually got past them with about 8:45 on the clock leaving a little left on my fast pack. I used my fast pack until I eventually lost it. I then just kept using Minmay to keep my HP up. When Hikaru came, I charged him straight on with missiles then when he got close I did Max's VF special and grabbed Hikaru and beat him down a bit. I missed him on my second special but had enough time to work him down with regular missiles. I had about 2:30 on the clock to take down the final ships. I was so nervous after taking out Hikaru that my hands were all numb and shaky during the final two ships. I kept thinking I was going to blow it. I know for a fact that I tried that mission at least a hundred times (about 15 hours). Now that I know how to do it, I'm sure I could do it again. Just took a long time to find the right combination of factors that suited me.
I think I am going to try for S on every level, but doubt I will try for SS. I still haven't gotten one other than the ultimate levels.
I am thinking about going back to try for ultimate and S on the previous Macross Frontier game. Do you have to finish all the ultimates first, or can I just get the S level trophy without playing ultimate? I'm pretty sure I can get S, but not sure about ultimate. I'm not going to spend another 15 hrs on a single level again!
