update your system ?
really, that's the easiest and safest and most compatible method.
Just be sure to have Haxchi already installed, or it would be a little harder to do it on 5.5.2 (not impossible).
If you really want to play without update:
did you try launching the game while being offline?
the console doesn't tell you "launch anyway" ?
If you can launch it at all, you might have to try with loadiine, but it has less compatibility.
again, the easiest method is to update.
What cfw are you using if its haxchi/cold boot haxchi then just go ahead and update and all homebrew will still work perfectly. If you are using mocha/browser hax then you can still go ahead and update the only downside is the browser hack is less reliable on the latest fireware. Also if its botw that is saying the system needs updated ignore this its a game update not a system update.it did come up lunch anyway and but said i need system update but if i do update the system will i loose the homebrew hack

So my Wii U is setup to boot automatically into CBHC Haxchi. So I can go ahead and update the system and not lose anything? Cuz I can’t get Smash or Mario Tennis to play cuz they ask for a system update.
