ok well sadly, after reading trhough the forums and finding this:Nanquitas has been offline since August, I've been doing the recent updates to BootNTR and NTR itself
Disclaimer: I've not yet personally updated to the (at time of post) most recent firmware 11.12 and Luma 10.0.1.
However, from reading around, I believe @PabloMK7 has you covered with following:
1. Latest BootNTR Selector for .plg plugin support.
2. This Luma 10.0.1 fork for .3gx plugin support.
I've tried just dropping the 9.1+plugin launcher .boot by @Nanquitas and nothing,
I've also tried the 10.0.1 which i assume also has the launcher and nothing,
so i guess i have to stick to the selector on latest luma and FW,
would really like to use the launcher with latest luma,
tthanks for your work @PabloMK7
