Capacitor is used for filtering the DC current.I don't think you have damaged anything.
Yout BT receivers power GND and the audio out GND might be isolated.It might stop if shorted.Try continuity test.
Does your phone have a 3.5mm audio jack? Try this mod without the BT receiver and make sure your datasette works.Don't try to run before you can walk  ;)

These are the steps,if you want to be able to hear the datastream from the datasette.


1.Press Windows Key and R to open RUN window and type mmsys.cpl



Or right click on the speaker icon and select recording devices.


Double click USB microphone,go to Listen tab and tick the Listen to this device box.
Go to playback devices and set your own speakers as default.

With this configuration,you can listen to whatever is coming from the tape.
DO NOT use listen to this device feature if you are going to record a game to tape.You have to disable it.

1530USB Datasette to PC Adapter / How to split TAP files
« on: June 10, 2021, 07:33:38 PM »
If you have a tape with several games on it,you can back it up,convert it to TAP file and extract the individual games.

Download and install the TAP Manager by Manosoft.

Create a new folder on your desktop and copy the path.



Run the Tap Manager,delete the path on the output directory line and paste your own path.Click on the home button to make it default.



Click on the load file and select your TAP file.Tick the boxes for the games you want to extract.Click on the split file.

Autoload from tape to Winvice

DOWNLOAD this Winvice with the script files.

Press play on the tape deck and double click the autoload.bat

It will run the audio2tap to create a TAP file and stream it to winvice.Do not use the warp function.

Head Alignment Without the Real C64

Put the tape in the datasette and press play.




Find and run the file headalign.bat in that folder.


After the azimuth alignment loads up
go to datasette control and fast forward and
go to datasette control and start


You will see the lines.At this point ALT+W for 1 or 2 seconds to catch up with the real datasette.


Use the screw driver to align the head.Try to make the lines thin and straight as much as possible.


This is not easy,you will have to try a few times.

1.You can use it with C16 or VIC20.It works the same way as using tapes.
2.I don't think 10uf will work.You can find 100nf capacitors in old sound equipment like radios and PC speakers.You can also try 100K resistor instead of cap.
3.There are many different boards.You need to open up your datasette and compare the board with the ones on this topic.

Tapecart SD / Setting up the Tapecart SD

You need to format a micro SD card with FAT32 file system and unzip the file below,

http://www.load64.com/up/sd.zip

Copy the contents inside the folder called sd to your SD card.Make sure browser.prg is at the root,otherwise you will get "Press Play on Tape" message.

You can use any micro SD card upto 32GB in capacity.Try to use 8 or 16GB even smaller if possible.Few users had problems with the 32GB ones.If you are using a Mac,it might create duplicate files on the SD card.

You can change any folder and file on the micro SD card but you need to keep the browser.prg at the root folder.You can find tons of games,demos,apps etc in PRG format at the following link,

http://www.planetemu.net/machine/commodore-64

You can load the browser by pressing the SHIFT and RUN/STOP keys or by typing LOAD command and pressing the RETURN key.

How to create TCRT files:

1.Download Tapecart Bundler.rar and open it to your desktop.
2.Copy your PRG files to the folder called PRG.You need minimum 2 PRG files.You can't convert a single PRG file to TCRT.
3.Double click Runme.bat. It wil create game-Vol#1.tcrt Rename it before moving to your SD card.

Photo above is borrowed from Cem Tezcan's Blog.

First thing you need to do is format a micro SD card (up to 32GB) with FAT32 file system.
Download the following RAR file

https://www.load64.com/up/zerosd.rar

unrar it to your desktop and copy the files inside the zerosd folder to the root.
Make sure start.elf,kernel.img,config.txt and the other files are on the root,otherwise Pi Zero will not boot.
Insert the micro SD card to the Raspberry Pi Zero,plug in the cartridge to your C64 and connect the serial cable.Turn it on and select a D64 file and mount it.
Use the C= and Run/Stop keys to autostart the first file on the disk image.But keep in mind,this doesn't always work.You might get a "FILE NOT FOUND" error.In this case type /* and press return.When it's loaded start it with the RUN command.

If you want to download selection of games,go to this website.

If you want to have it all,CLICK here.

How to update the Pi1541

Visit the Steve White's project page,

https://cbm-pi1541.firebaseapp.com/

Find the download section and click on the link says,

Latest Version 1.X (Pi0/1)

That is the Kernel.img.Just replace your old one on the SD card with the new one and you are up to date.
Please note,version 1.24 has some bugs like activitiy light and buzzer not working.You might want to wait for the next release.


3D Printing the Case

Here is Cem Tezcan's 3D design,

https://www.thingiverse.com/thing:4541283

If you are going to get this printed by someone else,make sure pick one option either the one with the M2 screws or the M2.5 screws.Otherwise you might get 2 sets of cases costing you twice.

If you don't have a 3D printer,join a 3D printing Facebook group and ask if anyone can print this for you.You might find some one willing to print this very cheap or even just the cost of the postage.

I managed to get good signal from that pin in the photo using a 100nf capacitor.You might also use a 100k resistor instead.

DC/Battery Powered Commodore 64 / Re: Internal Battery Pack Mod for C64C
« on: December 29, 2020, 04:17:09 PM »
I was getting about 2 hours out of the recycled laptop batteries.
Someone from Italy did the same mod and getting over 5 hours with brand new batteries.
I never measured the power usage.

1530USB Datasette to PC Adapter / 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.
