Strange Mapper 147 board

This board:

supposedly contains the same game and game version as this board (128 KiB PRG-ROM plus 128 KiB CHR-ROM), yet the chip markings seem to describe 128 KiB PRG-ROM but only 32 KiB (256 Kilobits) of CHR-ROM. Is the 27C256 a fake and in reality contains 128 KiB, or what's going on here?
