anyway i have every single disk backed up with personal backup systems (mfm , raw and so on) but the only downside is that 1, i cant boot them , 2. its only for backup ..
Well, unfortunately, this is next to useless for preservation purposes.
1) Many types of copy protection (on countless games) cannot be backed up this way.
2) You cannot tell what disks are now corrupted or have otherwise suffered bitrot - not uncommon! Fortunately our technology has proven to be very good at being able to read disks that even the games themselves do not. Note this is reading problems (common) not actual errors. The two are usually confused.
3) You do not know if they are modified. This (as well as 2) is a case of good or bad for you. But collectively, we can find the *good* versions. It just may take many copies to find them.
Believe me when I say that every games developer we have spoken to is 100% behind us on this. We are even working with at least 3 different ones getting their games legally public.
I hope you will change your mind about your games since otherwise they will just rot (floppy disks have an "official" 10-30 year lifespan - we estimate about 18 judging by all the 85/86 games that are beginning to loose their magnetism), and then of course everybody looses.

If you change your mind, please email us. It sounds like you have a very nice collection indeed.
Note, CAPS owns something in the region of 5000 games. However, there are duplicates, and many are error'ed/broken/modified.
