After more time than I care to admit, I finally have my second version of my CHX file collection for bubble2k16's Snes9x_3DS https://github.com/bubble2k16/snes9x_3ds/releases and PicoDrive_3DS complete. My gratitude belongs to Computer_Freak_2004 for his handy tool https://gbatemp.net/threads/release-chx-file-creator.552806/ without which I would not even have attempted this "project" and a HUGE special thank-you to sleepingkirby for fixing a long-standing bug in bubble2k16's PicoDrive_3ds v0.94 release (which basically crippled the cheat functionality, thereby making my attempt of creating .chx files for all my ROMs pointless). If you plan on using these cheats I would strongly recommend grabbing sleepingkerby's release https://github.com/sleepingkirby/emus3ds/blob/master/picodrive_3ds.cia
