AB's 'Gaming' section tends to get used almost exclusively by PC gamers, so your question might easily be missed in here. (You might find more people with long memories in something like 'Society & Culture', or even 'History').
However this site quotes 'Itchy me, star shee, Logo hutsy yutsy. - kill it':

This one suggests "Each, me, son, she, loco, hassi, passi, kill it", with a suggestion that the numbering might have more to do with Japanese than Chinese:

This post doesn't really add that much - but it proves that the blogger has searched the same sites that I have!

Your main problem might be that many such games would have had very localised words. The version used just a few miles down the road from your childhood home might have been considerably different to the one you knew. (When I started teaching, in northern Sheffield, I found that my colleagues in the south of the city didn't recognise most of the dialect and slang terms used by our pupils only a few miles away from them).
