I copied the Mighty Guy processing myself and tested it, and it seems to reproduce the processing of the actual machine.

TILE_GET_INFO_MEMBER(galivan_state::get_bg_tile_info)
{
int const attr = m_bgrom[tile_index + 0x4000];
int const code = m_bgrom[tile_index] | ((attr & 0x03) << 8);
tileinfo.set(1,
code,
(attr & 0x78) >> 3, // seems correct
0);

// same as Mighty Guy
tileinfo.group = (attr & 0x80) >> 7;
}

void galivan_state::video_start()
{
m_bg_tilemap = &machine().tilemap().create(*m_gfxdecode, tilemap_get_info_delegate(*this, FUNC(galivan_state::get_bg_tile_info)), TILEMAP_SCAN_ROWS, 16, 16, 128, 128);
m_tx_tilemap = &machine().tilemap().create(*m_gfxdecode, tilemap_get_info_delegate(*this, FUNC(galivan_state::get_tx_tile_info)), TILEMAP_SCAN_COLS, 8, 8, 32, 32);

m_tx_tilemap->set_transparent_pen(15);

// same as Mighty Guy
m_bg_tilemap->set_transmask(0, 0xffff, 0x0000); // split type 0 is totally transparent in front half
m_bg_tilemap->set_transmask(1, 0x0fff, 0xf000); // split type 1 has pens 0-11 transparent in front half
