The situation is even worse: The 1571 ROM version -03 won't load PRG files with the protection bit set, because the burst code checks if the file type byte is equal to $82. The first and only 1570 ROM had this bug already fixed, but I don't think that it will load USR files. I also don't think that there is a bug in the C128 ROM that is related to the file type. > what the record length is.

There are some multilevel games around that have all levels compressed in one big file, and before the game starts the drive obviously collects all the sector linkers to have quick access to any position inside the file. This process is very fast, comparable to the 15 seconds validate program that reads in all the linkers. Nicolas - This message was sent through the cbm-hackers mailing list.
