ok, I've been trying to get this game to work and here is my experience.
First my specs:
3.2U (original) Twilight Hack and HBC installed
4.0U (Nintendo Upgrade)
Banner Bomb used to install needed files (cIOS's and whatnot)
BootMii installed with PreLoader .29
ok, have been getting all my backups to work fine. I was initially using NeoGamma R2 and IOS 249 Rev 13. Latest backups that were working for me are Punch Out and MadWorld on the current setup.
I use Sony DVD-R media with the ISO burned at MAX speed with ImageBurn. (Just to make note, I burn all my games at MAX speed and never had any problems with them, or with the media)
So I try Ghostbusters with the same setup and get stuck at the Wii Strap screen. Nothing happens when I push the buttons, the wii drive sounds like it's spinning, but not reading. Also used all default settings with NeoGamma R3 IOS 249 rev 13.
Came on here and tried the suggestions, pressing A and/or Home, plugging in nunchuck, etc...nothing.
I've tried every IOS 249 from rev 7 all the way to 13 and all give me a green screen EXCEPT rev 13.
So I will eliminate all other revisions and say rev13 ONLY gets me to the wii strap screen.
Then I decided to use the most current version of NeoGamma. So now I tried R4 RC2, same as before all default settings. Still hangs at strap screen. Every time I get stuck at this screen, when I push any buttons on the remote, all 4 blue LED's blink almost like my remote is not communicating with my wii. So, for some reason when the game tries to load, it seems my remote looses communication with the sensor bar, or is just not able to be used. I noticed if you have BootMii loaded the remote does the same thing because you cannot use the remote with BootMii, only the power/reset buttons or the GC controller. Not sure if there is a connection, but maybe someone can chime in on why the remote is not communicating.
I read about ejecting the disc, so I tried this next. Just before the game boots with NeoGamma and the screen turns black I hit eject. A message says "please insert the Ghostbusters disc" During this time, the blue #1 LED on the remote turns off then back on again and stays illuminated. When I put the disc back in, the strap screen comes back on but no button presses work...however the LED is still illuminated but remote still not working.
After this I did the same method but tried hitting the home button as suggested. When the strap screen comes up I hear the DVD starting to read more which it didn't do before. I finally get past the strap screen!! Game loads, set up my save, and I can play game. Cool right?? WRONG
I try again and again to do this to see if it works again...it doesn't! Reboot after reboot doing the exact same procedure doesn't produce the same results. Then I decide instead of pushing the home button, to push the "A" button...surprise, it works!! So reboot and try again...guess what?? DOESN'T WORK
So I try "Home" button again...doesn't work! Reboot again, and try hitting "A/Home" at the same time, well this seemed to work! Reboot again, nothing! I cannot get two consecutive boots to work using the same method, and sometimes not even alternating methods. It's almost like it is completely random. I don't get it...but something is happening to make this work. It ONLY works when I ejected though. If I don't eject, like I said before, my remote will just flash all LED's.
Sorry for this lengthy post but I just wanted to share what was happening with my Wii just in case anyone might be able to tell why it's doing certain things at certain times, and why it will work one time and not another. Very strange.
