Failed Backup Troubleshooting
« on: December 15, 2020, 05:59:12 PM »
Alright folks.These are the common problems I come across.

You backed up your tape but it doesn't work on emulator.

1.That tape game might have copy protection.

Downoad Vice 2.2 and start the x64.exe.
Go to Settings->Drive Settings -> Set the Drive 8 to NONE

Try your TAP file again.Vice 2.2 version is less picky and warp speed is around 3000%

2.Tape might be damaged.It is very likely chewed by the datasette 30 odd years ago.
That tape might load and run on the real hardware just fine.Because C64 loads and runs the program even if it has corrupted data.It will crash or glitch out during the game play.
Emulators crash while loading if there is corrupt data.

This is how it looks if the tape is damaged.



If the game is on both sides of the tape,you can backup both sides and stitch the good parts with the bad ones using audacity.

3.Finaltap gives 6%
If that game loader is not in the Finaltaps database,you will get very low percentage.
Do not clean/optimize as it might ruin that TAP file.
You might try to clean with the program called Tapclean as it has a larger database.

Download this TAP file and record it to a tape.Backup that tape and check with Finaltap.If you get 99% without cleaning,
it means the adapter,datasette and the tape is OK.
