If its only about updating the hardware you have with recent firmware - just put the complete archive on an sd card and put it in before powering on, the device will pick the right firmware automatically -- https://cc65.github.io https://rr.pokefinder.org https://vice-emu.sourceforge.net https://magicdisk.untergrund.net In headlines today, the dreaded killfile virus spread across the country adding 'aol.com' to people's Usenet kill files everywhere.
