Please save in a pokecenter before updating if using a save from a previous version, otherwise you risk corrupting your save. You should again patch a CLEAN YELLOW ROM if patching from the IPS patch. Do NOT apply the patch to an already patched Yellow Legacy ROM. Please be smart, take a backup of your save before updating just to be safe.
Patcher: https://www.marcrobledo.com/RomPatcher.js/
PSA: Before you get started patching anything, load your base yellow ROM into rom patcher js (or a hash checker) and check the SHA-1 hash. The base yellow hash should be SHA-1: cc7d03262ebfaf2f06772c1a480c7d9d5f4a38e1. If it is not exactly this, you have a modified or bootleg yellow ROM and you will have to find a real one. Similarly the hash of your 1.0.10 patched ROM should be SHA-1: 2ac87de42afc70ef6016805acb3b206644417f97, again if this is not exactly this, you have done something wrong and should repatch.
