Not trying to be "that guy" but going to beat this dead horse one more round...

First a big thanks to everyone who has responded and reached out with links and suggestion - much appreciated!

I am able to successfully get the links for everything that is not software list related (MAME, MAME CHDs, Extras, etc) but keep getting timed out on either of the software list related ones (MAME SL and MAME SL CHDs).  I am at a point where I only need a very limited subset of the SL CHDs (specifically ~1400 PSX files the the Saturn Rayman prototype), so sadly what I am looking for is specifically what the PD links do not want to let me see.
Are there not enough seeders, or specific times that I should be looking to try for?  Any thoughts you can pass along are great, and I PROMISE not to ask about this again!
