When I looked at the binary of some games, I see some weird text, which looks like comments or metacode of some higher language, (examples shown below). Any clue what's the purpose?

*Final Fight 3

*1997 Super HIK 18-in-1 (JY-101)

*1997 Super HIK 21-in-1 (JY-105)
Image

*Dragon Ball Z - Super Butouden 2 (Unl)
This is dumped from the blob game (right), comparing with the DBZ that is floating on the inernet (left) shows that those text were cut off, so maybe this blob is first release or something

A lot of old-fashioned assemblers and linkers neglected to clear RAM before assembling into it. This caused unused areas to have whatever data happened to be in that part of RAM, and in this case, it happened to be source code. See "Category:Games with uncompiled source code" and "Final Fight 3 (NES)" on TCRF.

What was the GBA or DS game(?) that accidentally got filled with a bunch of cached porn websites? :D
