I think you've misunderstood this, this is for getting open the browser to then exploit its vulnerabilities on 1.0.0 (see below).
3.0.0 has a browser, and has smhax.
In Japan, PuyoPuyo was a launch day title and was available with 1.0.0 as a Demo, I believe. Otherwise, you will need the original game cart which runs on 1.0.0 and can used as a way to force open the web browser. This is otherwise difficult for 1.0.0 because it didn't have, at launch patched in, browser capability used for wifi sign-ins and such.
