No More Heroes 2 crashes after boss battle.

I'm running on 4.0 system menu, retail copy of the game, and I blocked updates via StartPatch. I haven't had any problems until now. I've played through three hours of the game, and RIGHT after I kill the giant robot boss (Letz Shake NMH1), the screen goes black and there is a loud buzzing sound. No buttons work, and I have to shut it down manually.

I think it might be because it needs an IOS that I don't have, but I thought if that was the case, then the game wouldn't have loaded initially, right?

I realize this may be a long shot because the game only came out today, but if any of you can help me out, I'd be grateful.

If it was due to an outdated IOS the game would likely have black screened when you tried to load it, not after already playing for a while. Some trackers took down one of the versions that were released claiming it was a bad dump: No idea if that's true or just user error, but if the crash happens the same way in the same spot every time, that might be the reason.

Yeah, I figured that's what would happen if it was an IOS issue. I can see why a bad dump would do this, but I have a retail copy of the game (I grabbed it from Gamestop earlier today), so I don't see what the problem could be... Maybe it switches what IOS it uses after a certain point?

Nevermind, I tried playing through the battle a fourth time for the hell of it, and everything worked. I guess maybe my Wii was overheating or something.

it sounds u've find the cause of interruption
similiar problem was echoed by ISO players. they fixed it by reloading the game. fyi.

I've also just encountered the same error when fighting the space suit boss so it wasent ur wii over heating.

Hey, I got the crashes too, but it was hard to trigger fortunately. However, I have this little problem, when I'm fighting Pizza Batt Jr. I can't seem to kill him...I got him down to about 1/3 or 2/5's health, and it just doesn't go down any further. He's like invincible, I think then, he was supposed to go into his second form, but I can't finish this battle at all because of this debilitating glitch. I've been booting from a USB game channel, using ios 249, no codes, doesn't work, then I booted both from USBLGX channel, and HBC entry, and I still can't get him to his second form. I got the latest USBLGX, is it a bad dump? I'm playing the WIISOS dump, I put it on my drive with WBFS Manager 3.0.

I got a 4.0u softmodded
