Bypassing the patch is for glitching & spawning with ER but these are mods & the CRC checks your .rpf for irregularities in file size, fonts & other stuff then places you in modders pool. I have fun with my mates as we all had the same mods, public & private but Apoc & Matrix always had the best source codes & other modders leached & leaked their work, so they released it. I learned from all the old post's & YouTube tutorials, but this game is way outdated now butt still in my Top 10 Favorites.
