Lazarus is an Emerald hack. The base I will name is the US Emerald dump whose SHA-1 is f3ae088181bf583e55daf962a92bb46f4f1d07b7, the same figure as the Emerald page, because that is the clean dump the pret repository documents. The research note says the hack wants a clean Emerald and does not pin a smaller revision inside Emerald. If your dump's hash differs, stop. A patched or trimmed Emerald will fail a source check for the same reason FireRed 1.1 fails a 1.0 patch.
The Rebit guide published on 20 November 2025 calls Lazarus a BPS patch and names Nemo (Nemo622) as the author. That is the article’s publication date, not a separately confirmed release date. Its instructions direct readers to the creator’s Ko-fi page at https://ko-fi.com/nemo622. The BPS label and author-channel attribution come from this one guide; Ko-fi restricted automated access during this review. An earlier planning note said UPS without a public source, so it is not counted as a competing published claim.
Apply whatever file you obtained from that channel with the home patcher. If it is BPS, a wrong Emerald fails closed. If a copy in the wild is UPS, the same failure text can appear. If a copy is IPS, you lose that check. I would not take an IPS of Lazarus from a reupload.
