Capability-wise, I don't think so. But the (published) browser exploit that's used to boot Mocha isn't 100% stable, sometimes it'll just freeze up the system and force you to hard poweroff.

Anecdotally, this freeze seems less likely to happen if you boot into the exploit immediately. Either by having the exploit page be the first thing that shows up when the browser is loaded (so the page that was last accessed), or with Indexiine.

Indexiine is probably a good method to start with. It changes the browser's start page to the exploit, loading into the Homebrew Launcher automatically without having to press "Run". If Indexiine seems unstable, then you could plunk down the $7-$10 and get Haxchi.

Indexiine is a little awkward since it edits a NAND/system title, doubly so since it's the one that's used to access the homebrew launcher in the first place. I've tested out installing/uninstalling a bit, it seems to work ok. If you do somehow end up with a "browser brick" and can't access homebrew, BluuBomb is a bailout, though kinda complex to set up.
