Seeking Theme Videos for MAME Titles

[BamBam]

Good day folks,

 

Let me start by saying thanks to all of the contributors for the work put into the theme videos, and all other artwork files for this hobby.  They make my Launchbox Arcade look very professional.  I am unable to locate Theme Videos for the following games from the MAME side of the house:

1. Sega Rally Championship Twin;

2. Silent Scope; and

3. Time Crisis II

I scoured the FTP server for the videos, but cannot locate them.  I also used the Launchbox media scraper, but it does not show videos available for these titles. 

I would appreciate your assistance in pointing me in the right direction.

Cheers.

John
