We are working on the new firmware that increases sound quality a lot and also has the 3-bit volume control for FMPAC and SCC channels separately. The firmware will be available once it's properly tested.

Compare the sound quality:

Old firmware: https://drive.google.com/file/d/0B7xjYWTXlb9mR1MxaldQOXpfMVk...
New firmware: https://drive.google.com/file/d/0B7xjYWTXlb9mclgzTnM3Y2drQmM...

Ignore the occasional clicking sounds - this problem is already solved.

Great news !!!!!

What kind of firmware will be updated? The carnivore2.pof file or the BOOTCMFC.BIN file?

The firmware's file (POF) will be updated. When we decide how we implement the volume control, I will be able to tell whether any other components will be updated.

Must will be updated hardware components? This aren't good news...

No, hardware will stay the same. Unless there's no other solution as to store the permanent volume settings in a small optional EEPROM. But we will try to avoid this.

The optional M93C46 eprom? No problem for me. I installed it in all the boards that I mounted.

I have a question. The new firmware, will also have the new SCC+ functionality ?

Yes, the new firmware has the SCC+ functionality included. Would be nice if that could be also tested. I sent the firmware file to you an hour ago.

Replied my impressions in the e-mail.

We have reversed the changes for the SCC filter, now it sounds as before. The FMPAC is not affected - it sounds better and louder. Also the volume control has been implemented into the bootblock:

I will send the updated bootblock and the new firmware to 8bits4ever and Carmeloco. If they are happy with the changes, I will released the new files. My own tests show that everything is OK. :)
