Can I reprogram a White Noise Machine

[Datastreem]

Hey,

Found this site when I just searched a chip that's on the board of a White Noise Machine that I just bought, I'd really love to be able to edit the sound files, are even add my own. I'm using it for my Tinnitus and it's got 30 sounds but some are just wasted.

I see there's some programming pins etc. I'm a dab hand at micro soldering etc. Been into electronics for years, I'd love to be able to have a go at this, I see the chip MIX2032 is the audio output chip, The TC4056A is for charging the battery, I think the 25vq64asig is the flash chip, but I can't find anything on the one in red (SZY84A2 U359G2412)

I see there are also some jtag connections, ground, V+, negative data t D– (DM) positive data terminal D+ (DP)

Is this possible?

Thanks so much

Try to read the chip with an SPI flash programmer.

SZY84A2 U359G2412: Can you post a clear picture of the chip in question? The photo is not sharp enough to see clear details, but I think it may read 5ZY..., not SZY... But looking for 5ZY84A2 U359G2412 doesn't return a result either so other letters/ciphers may be wrong, too.
