Official Pico 8 will not work in RG35XX H (Batocera V40)

I followed the wiki page. Tried using Linux & Rasp zip, .cfg created and placed at the location, and create splore file. Followed the step for Armboardx64, but still did not work. I use V40 and have a Windows PC (if it's mattered) since there's a step to make "pico8" file executible (?). I can play Pico 8 games using the Batocera's Stock and manual download the game in PC, but I really want to use splore to just explore and download right through it. Pretty sure I missed or wronged a step. Help?
