uint16_t xindex = m_oam[oam_address + 1] - 8; uint8_t pal = m_sgb_pal_map[(xindex < 0) ? 0 : (xindex >> 3)][((yindex - SGB_YOFFSET) >> 3)] << 2;The < 0 check never works since it is unsigned - xindex also seems to underflow to 0xffff causing this access to be always out of bounds since m_sgb_pal_map[20][18]. |
