C64 BT2: file - track/ sector list

[Weber G]

Since BT2 (C64) has a track/ sector loader, there are no file names in track 18 of the disks.

If someone is interested in, here is the file - track/ sector list:

I haven't investigated each file yet (not so much time). Therefore many comments are empty. Load address "EAEA" means => not investigated, yet.

disk 80 => character disk
disk 81 => dungeon disk 1
disk 82 => dungeon disk 2

[Darendor]

How does it know which disk it wants? For instance, it prompts you for "Insert any DUNGEON DISK", then reads that disk, and if it's the wrong one it tells you which one to insert.

[Darendor]

Also, in case anyone cares, the "city events" are always loaded to $9A00 in memory.

[Weber G]

How does it know which disk it wants?

Check the code beginning with $1CDC.

Check the code beginning with $1CDC.

Yeah, I did that.

I ended up with:

Do you understand that code? Check what's in $E0 and $D4 and follow each command, then you will know how it works to identify and compare the disk numbers.

I can not explain you all the code... that would go beyond the scope...

[Darendor]
