Decompile 9 functions in Source/Client/Mode/LoginMode.cpp, Source/Client/Mode/CLoginMode.h
Batch #4181 by youko: 4 byte-identical, 5 confirmed by peer review. - fn_22265 CLoginMode::SubD8D4F0: byte-identical - fn_22270 GetClientType: logic confirmed by peer review - fn_22272 CLoginMode::GetMaxCharacterSlot: logic confirmed by peer review - fn_22273 GetUserCountText: logic confirmed by peer review - fn_22274 CLoginMode::ReceiveCharacterSlots: logic confirmed by peer review - fn_22276 CLoginMode::SubD8EDC0: byte-identical - fn_22279 CLoginMode::SubD8F560: byte-identical - fn_22280 CLoginMode::ReceiveCharacterList: logic confirmed by peer review - fn_22288 CLoginMode::SubD91780: byte-identical Peer-reviewed-by: Yommy, superintelligence, tayoba Accepted without human review: peers confirmed the logic ("same" ahead by at least 3, with 70% of the votes). Adds to the build: Source/Client/Mode/LoginMode.cpp
