I am trying to read and save a 27SF512 chip using a APU1 and Tunerpro. For some reason, the file saves as a VLC Player file. Its labeled as .bin but I sent it to a member here to read and it will not open. What am I doing wrong?

*.bin is a file extension that is associated with VLC player. You can associate any file extension with any program, it doesn't change the file, just the icon used and the program windows thinks it should use to open it.

So the person I sent it to should be able to open it? Im a newb here with this stuff.

It’s been awhile since I’ve used a apu1. You should be able to use flash and burn read as a 27c256 then save buffer . The extension would be a .bin

If your trying to post it on a thread you will need to zip the file.

Im about a week into learning this stuff and I think Ive only consumed about 3% of the info that out there to learn. With that being said, what is flash and burn? Is it a program I need to download?

I was trying to send it via email to a member here so he could look at it.

I am trying to send the file to ULTM8Z (Mike). I dont think he is familiar with Autoprom

Flash and burn is a stand alone program used for the apu1 and burn products.

Thank you. I am not familiar with that . I will look into that now.

I think it’s easier to do a read that way than using tp, if you read it as a 512 you need to set the offsets. So read it as a 27c256

Tuned,

Does it matter what the buffer start address is when he does the "read chip"? He's trying to read in a 27S512 chip and hte buffer start is currently 0000. In the screen shots he sent, that's the only difference I detected from how I work it on my minipro burner... I use 08000

It is asking me for chip start address and finish address as well as buffer start and finish.
There is no list of chips in the supported chips window.

I changed the start to 08000 earlier and it still saved as a VLC file. I never bothered to sending it to you.

If you read as a 256 you don’t need the offsets . The 512 offsets are here.

000000 -> 007FFF
008000 -> 00FFFF
I don’t know why it’s not saying supported chips

I closed the program and restarted it. supported chips are now listed.

Ok, so I think the answer to my question is yes

Right on ! Making progress

Try sending to me. It may work now.

I sent you the file that was read and saved using the FLash N Burn software. It still saved it as a VLC file though.

Sorry I never saw your question but yah those are the correct offsets or reading as a 32k does the trick no other offsets needed unless the default was set to burn a 16k file 27c128.

Success!

The one with the start address at 08000 works.

Can you even rename with newer windows to change the extension ? (Vlc to .bin )

apparently... It opens just fine in Tunercat

Large file 64k with the incorrect offsets ?

no, its still a 32kB file..

Weird but glad you can read it now
