Hacked this together awhile ago- but it was never released,
there was an app on PSN (PCSC80021) that had a webbrowser in it, which has better HTML Video support than the offical one-
so i (and a few others on CBPS..) tried to see if it could load youtube, after changing user agents alot i found it works on longer videos than just 2 hours
it also lets you load videos w ads, which you cant do on youtube in browser
weirdly though, it refuses to load on Devkit, i dont know why. testkit and retail work fine thou.
ld-preload/ is LD-PRELOAD.SUPRX which i wrote some assembly code at the bottom of the EBOOT.BIN to make the app load at startup,
and forcemount/ is PRELOAD.SKPRX.
