I presume he meant the sound of the tape mechanism?

Very strange want...

Disk drive noises I can agree with (even tho the C64 head was quiet anyway) but tape mech noises are just a bit, well, weird..

Of course, there were lots of tape recorder that were producing loading sounds from their speaker.
Some of them you can find on ebay.
They were c64/c128/vic20/c16 nice compatible tape recorder.

This was necessary if you had to modify azimuth controller.
If you hear clean and treble sounds the possibility of a correct tape loading definitely increases

aahah no no it isn't the tape mechanism that I want Smile

By the way, only Emu64 has implemented it some time ago.

No, please carry on with other stuff Bero...

If you ever want to put it in as a choice later it might be nice but only as a last thing when you have nothing else to do.

I've implemented it:

Code:

======================================================================= bero ===
Version: 1.00.2012.07.01 Build 701 SVN revision: 2464
Date: 30. June 2012 Time: 22:58 UTC
--------------------------------------------------------------------------------
- Updated cartridge emulation code, very many fixes and additions
- Added "Automatic reset at autostart" setting
================================================================================

uh. the original commodore datasette did not, however.

much better idea to simply use a program like http://noname.c64.org/csdb/release/?id=49944

@Bero...

Simply, thank you.

You are a star...

ah, the time spent in the early 80's fast forwarding tapes to find the break between 20 games saved with turbo tape on a c90 cassette. Halcyon days Smile

Right, it's easy to find the ending or starting point of a turbo tape program with audio output feature

LOL...Yeah, been there too..

When I got my disk drive for my Atari 8bit (got my 64 after) it was like I'd won the lottery, no more damn tapes with compilations on..!!

When I got my 64 I got a disk drive straight away...(god I was skint for months afterwards)

Lol..Phew...

It shows you, I thought the tape load output was on all the emu's, never noticed it wasn't..Time to listen to a Novaload..

POKE 54296,15 and turn the volume way up - no need for audio output Wink

No, this is for c64 audio output, not the audio from tape...
And c64 audio output is very bad and full of garbage

And also C64 audio output is already emulated by micro64.
Look at the audio menu in the emu

Yes, and through that garbage you can hear the digital signal from tape, at least with all the monitors I have tried it with.

Took my work laptop home just to be able to play around with the fullGPU PAL emulation. Quite nice! It's fun to try to get the picture look like "it used to be" :)

All the various VIC-II glitches, are they "just" rendering effects, or are they somehow based on actual emulation/simulation of VIC-II behavior?

They are also real emulated. For example the VIC-II emulation writes AEC & BA data flags in the otherwise unused alpha channel of the 32-bit floating point RGBA input texture (which is internally abused as YUVA texture here) for the first VIC-II glitch emulation OpenGL 3.0 GLSL shader pass.

And the VIC-II NMOS luminance glitch is also real-emulated in a right way as much as possible.

You're wrong. Due to electrical interference on the real C64 hardware the tape signal leaks to the C64 audio output. Setting maximum volume on the SID makes this interference more obvious.

I know but I make this example

It's the same thing drinking coffee with a spoon of sugar or a glass full of sugar with a spoon of coffee? .. Smile

Gets better and better every day...Thank you..

Just a question, that undead demo that you added support for to make the system like a C64C, does having the system set as a C64C break anything game wise that you know of?

Just trying to see what is a good default / most compatible setting from the fine list in the new hardware settings menu?

Thanks again Bero....brilliant work.

Nice work. The radial option is definitely something different compared to other C64 emulators Smile

Hi Bero,

Just re-enabled telnet on Win 7 but I have to say I am at a loss how to connect to it.

Its enabled in Micro64 and the port is still 3172, I've tried telnet 3172, telnet port 3172 etc etc but I'm afraid I have to admit I don't have a clue what I'm doing, not used telnet since I was on the Amiga and the brain isn't what it used to be Smile
