Something Strange with VIC-20 Names That I Don't Understand

[load81]

I was looking through Commodore VIC20 - Games - [CRT] - Singlepart (TOSEC-v2017-10-23_CM).dat the other day and I noticed something strange about the way certain files are named.

In the case of Jupiter Lander I see a strange artifact in the name I don't understand.

Jupiter Lander - VIC Super Lander (1981)(Commodore)[A000]

I see the title and subtitle, the copyright year, the copyright holder, and this little blirb [A000] which confuses me. What is this? Cartridge label, but a Google Image search suggests this is wrong. Other entries such as Jupiter Lander - VIC Super Lander (1981)(Commodore)[a2][A000] push the [A000] past the dump flags and seemingly into the "more info" area. So, what added information is this supposed to convey?

The only theory I'm left with is maybe a two-byte memory address. If that's the case, why isn't it $A000 or 0xA000 as this would be more clear?

Thats correct, it's the start address of the cartridge, hence it's in a [] bracket.

as of why it's not 0xA000 only the prior renamers can say that .

to know more about the naming you can read the TNC here.
