Hey guys, I had an old stuffed toy with a speaker inside. I opened the toy and found a little remote with a button to start the sound. I opened it up, the the motive being to put my own sounds on it, but have no clue how to do it. I have access to a soldering iron and I'm assuming a computer will be involved :P
Probably uses some shitty microchip with flash, good luck trying to figure out how to flash it.
