I think that there is no reason in buying Japanese Puyo Pugo, right? It was only as example...
PPT(JPN) is only an example used because, as it happens, is how you also got access to the 1.0.0 browser which was otherwise not 'active'. On higher firmwares, it is unnecessary, we all have easy access to the browser.

"I dont belive in fate, but [...]" - Plutoo as he found an out of bounds read in the pl microservice.
The entire hack (as i see it) currently bases on the sm service to escalate to kernel... In case they dont find a practical way to escalate from an universal usermode applet (preferably webkit) we are stuck at 3.0.0
This was likely what was reported in the 3.0.0 HackerOne submission that brought on the complete key-revoke in 3.0.1, since the issues go well beyond ROhan's weird access conditional with the Mii's but all of it ties into a strange escalation of permissions to gain control of sm and then the kernel.
