Hey, so you’re looking after that 8‑bit palette, huh? The safest thing is to keep the original ROM exactly as you found it, then make a few copies. First, write it straight to a USB stick that’s dedicated to archival – no other files on it. That’s your Level 1, low‑risk copy. Next, copy it onto a flash drive that you keep in a different room, maybe a cold‑storage box – that’s Level 2, medium risk. Finally, put a copy on an external HDD in your backup cabinet, label it “high risk” because it’s the only one that can get wiped by a drive failure or power loss. Don’t let any cloud service touch it, because who knows when the cloud will forget our 8‑bit nostalgia? Once you’ve got those three, you can safely tweak the palette in a sandbox, knowing the original is still safe. Also, keep a spreadsheet listing the ROM hash, version, and the date of each backup – that way you can roll back if anything goes sideways. Good luck, and keep those 8‑bit colors pure!
