Before I even begin, let me just say that this post is not like any other problem people have been posted about NSMB so please bear with me. I'm running a virgin 4.2U that's been softmodded using the simplistic guide posted elsewhere in this forum. I'm on Waninkokos cIOS 249 v14 and have a variety of USB loaders (Neogamma, Configurable USB Loader, GX, etc). I have had no problem getting NSMB to boot up (both PAL and NTSC versions with patched main.dols). However, once I do begin playing, the sound for touching a coin has been replaced with a loud screeching noise. After I touch 3-5 of them in a row, the game will ultimately freeze up and I will have to manually power down the Wii. All other sounds and background music are fine. I have tried a variety of troubleshooting processes including: 1. Switching from a component cable that goes through my reciever to the original composite cables directly into the tv. The coin sound is still a screeching noise and the game will not lock up, but the noise will play continually after touching too many of them and will continue screeching until the end of the level. 2. Switched televisions- again, the same issue. 3. Played an original copy of the game. Same thing believe it or not! I thought it was an issue with the backup loaders, but now I'm wondering if it's the actual system hardware. I'm just surprised it's just this one little sound byte that can be such an issue as all my other games work perfectly. The only reason I'm considering it has anything to do with something related to the hacks is that I've never had such a problem prior to the softmod. Are there any known issues with the any of the basic cIOS's or IOS's that could cause this? I realize I'm probably out of luck since I doubt anything that's been hacked would interfere with the original copy of the game, but I thought I'd ask the experts and see what recommendations I may get. Any help or guidance would be greatly appreciated! Cheers!
