I am in the process of doing TAS of arcade games (with MAME). I have tested many Eggs and some marked as rumor, so I have some corrections that I can send to someone to update the site.

My videos of arcade TAS are on YouTube

Currently I am doing a TAS of Gaplus, and I have found that on every wave (so far) that has a formation, there is an hidden extra life flag somewhere, like in wave 1.

Here is screenshots of Parsec 2,5,6,7,10,11

So, is there someone I can send my updates for the Arcade Easter Eggs on the Digital Press web site?
