There was never any other standard for cartridges, as far as I know.
Actually I was about to make my post longer, but after realising that it would become a wall of text and getting tired I ended up cutting it short (the fear of the frequent auto-log-out problem of the forums didn't help either, though I
did press Ctrl-A Ctrl-C frequently when I typed). While it made sense to have only one way of displaying the size of a cartridge for most systems it was not the case with the Famicom, because of its (usual) CHR+PRG ROM configurations for the carts. Most magazines BITD showed game size in one single number, such as 1M(bit), 2M(bit), etc. However, certain magazine(s?) did write something like "1M + 512K", showing how its CHR and PRG ROMs were configured, and in case a cart contained RAM, be it CHR RAM, some additional work RAM or battery backed ones, they even went this far to write something like "1M + 512K + 64K SRAM", so there was no real standard to show how large a
Famicom cart was. But of course they're all shown in bits, not bytes, so it's not contradictory to what you said. The difference in "standards" I mentioned was just whether they specifically showed the actual CHR-PRG ROM configuration, not whether it was shown in bits or bytes.
But! Actually I didn't know the CHR-PRG separation thing of the system BITD though. And since I was more familiar with how FDS stored stuff, having hacked game graphics on the real system and the like, and that
pirarchived cart games for game copiers usually worked like 1 disk storing 1M of data, so a 2M cart game spanned 2 disks, so I was really confused on what things like 1M + 512K actually meant.
