Ah never mind, I did try to exchange the 74xx chips but it didn't help.
And what's worse, I realised that the Rom chips must be custom made - with 28 pins there is no way these are 27C512 with only 64kb each, cartridge says that it contains 31 games, and 64x6=384 which leaves only something like 12kb per game which is not possible ... and to rewire 6 eproms (27c010) is just not worth the effort.
