UPDATE 12-21-17
Today is a truly Magical Update! Thanks to Rhester72 & DanTheMan827, you can now use Custom Firmware Switching Magic! I put together a video showcasing this as well as two other nifty USB-HOST Relative Updates. These are USB-HOST dedicated Cores & converting NTFS & Fat32, etc., Flash & Hard Drives into a more suitable and reliable format for use with NESC/SNESC. You will need to use Hakchi 12-14-17, and can Update it by Flash Kernel, Rebuild Kernel, & Memboot! Many Cores Updated, per usual...including MAME 2003 (Build Fixes; Thanks clienthax & twinaphex!), MAME 2010 (Build Fixes: Thanks orbea & twinaphex!), FBA 2016 (Save State Fixes; Thanks barbudreadmon!), Eighty-One, Genesis Plus GX, Mednafen VB, Mednafen PCE-Fast, Mednafen SGFX, Mednafen NGP, SNES9X, RetroArch (Both Fceumm & Nestopia). I renamed both RetroArchs to keep them from being separate, and to notate which RetroArch Version they are on
Enjoy Today's magical Update, and here is the video related to the 3 USB-HOST specific enhancements!
And, of course, the actual Update
