The two Cube Tech games you mentioned are included in the attachment in
this post.
I have the first four ROMs (those hacks of Inventor hacks) you listed that I found within one of the numerous NES ROMsets I have. I have attached the 4-pack below.
As for Titenic, I'm not sure if the Proper Version from October 2021 is the exact same as the one that NewRisingSun uploaded on Discord back in January 2021 with ABABSoft in its filename (that of which I do have in my NES ROMsets) or if it's a different version from that.
You can also try asking around the BGC Discord if you haven't yet if anyone these has the remaining ROMs on your list.
