How do I know if a game is over 72 mins?

Is it true that if it is over 72 mons that it cannot be used with Knife Trick or No-Solder Mod?

I have tried Spiv website for info but it makes no sense.

Please help!

When you go to burn it , it should tell you how long it is. If not you could always open up the .cue file and check.

i think that if its over 71 mins it wont boot with a knife/cog/etc or no solder-mod swop not 72 mins (although i could be wrong)
