Would it be possible to add support for alternate/duplicate platforms? As an example, I have my PC Engine ROMs split between PC Engine, PC Engine CD, Turbo Grafx, Turbo Grafx CD, and SuperGrafx. While I could edit the config to change the folder name for each scrape, or rename folders back and forth, it would be easier if it could read the es_systems.cfg (which contains the "parent" system's name in the tags) or I could add one of the alternate platforms to the config with something like:

[pce-cd]
scrapeas="pcengine"

The Pixel theme contains images for a lot of those alternate platforms, so I've been using those names as a guideline while working on my setup. That could also be useful for having a pre-set list of aliases for the scraper.

Thanks!
