30-in-1 multicart -> 16 chips (George Boole's nightmare)

There are 16 chips. Do you think this is come special crazy mapper?
It is just simple 16 kB / 32 kB NROM game + mirroring select with register placed at $7000-$7fff.
Most of the chips are for some crazy PRG bank mixing. But they could use just 4 MBit PRG + 2 MBit CHR + 74273 + 74153 and 2 diodes + resistor to generate clock to 74273 (when placing it at $8000-$ffff).
The lookup table of values written after selecting game 01-30 is placed at offset $71 in ROM :
01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 1E
They are sequential, so looks like they combined the games' PRG (or CHR) in bad order, ordered mask roms for them in factory and after doing prototype PCB they realized that they combined those files in wrong order, so they needed to fix it in hardware by using those gates.
Also, the menu routine is weird (game selected by entering number, instead of selecting from list), no game names.
