iNES Mapper 252 is used for Waixing's Chinese localization of the Japanese Namcot game 三国志: 中原の覇者 (Sangokushi: Chūgen no Hasha). It uses a clone of the Konami VRC4, with the chip's A0 connected to CPU A2 and the chip's A1 connected to CPU A3 (VRC4e, Mapper 23 submapper 2). It has 8 KiB of PRG-RAM at CPU $6000-$7FFF, and 1 KiB CHR pages 6 and 7 are CHR-RAM.
INES Mapper 253 is the same, except that it's 1 KiB CHR pages 4 and 5 that are CHR-RAM.
