Hello,
Probably a stupid-question, but I'm working on something...
I have created a script that import the content from the dat files into MySQL. A quick check for oversized ADFs gives me:
Code:
MySQL [tosec]> select name,size from roms where size >923648 and name like "%.adf";
+--------------------------------------------------------------------------------------------------------------------+---------+

What are these oversized ADFs useful for ? I mean, a floppy can hold only 164 tracks (but normally the last used is 159, which is 160 in total), so as everybody knows, the ADF should be 901120 bytes, nothing less and nothing more except in some special cases (I have found some disks to be readable for the last 4 tracks, have not checked the extra data), so a maximum with 164 tracks would be as above, 923648 bytes.
Even more odd, one file above is 923649 bytes..
Continued below (20000-limit)..
