Many of these disks are too far gone. Cleaning won't help most of them- they have banding from where the coating has come off the disk. Some of the Apple disks are from 80, which is getting on towards 40 years now.

Okay. Thats true with any 70's / 80's platform games - time is running fast and disks won't get better. They are still useful as all A2 dumps are now valuable so all good.

Indeed, I think these are among the first few A2 game dumps we have; I mostly had some OS images I used while adding support to DTC.

Rakki- I will take a second look at those disks you mentioned to be sure they aren't salvageable. Also, I took some group pics so you can see the labels.

I am reading the original factory pressed disks as:

Code: Select all

dtc -dd0 -p -a8 -f"TitleName/TitleName_" -i0 -g2 -y -i8 -l8 -t10

Thanks rcade, I appreciate your help. I can check only consistency for those unknown RAW steams and quality of signal etc. but cannot check the data integrity based on format. Current DTC version doesn't support A2 formats and plan is to add support for them through user defined formats.

Photos were very good, thank you. Obviously all games were loose without original boxes or owner just send disks? No problem if there are no photos available of "all" like box, manuals etc. Value of those dumps is high so good work!

Btw, Bomb Alley doesn't use halftracks. That effect of few sectors between noise comes from disk not being exactly centered on the spindle, likely during mastering. Seen this from time to time.

I only have the disks- If the owner has materials, he didn't send them and may be able to photo them for you.
