Been waiting a while to do this update but I wanted to order some of the merchandise myself to check the quality and the service provided by Cotton Cart, the online shop that fulfils the orders for t-shirt etc.
I also wanted to use the Shop section to launch my latest NES music tool, 'droNES'
No, I'm not going all capitalist and it's been a hard decision for me to start charging for my NES software but my time is precious these days and I don't think it's too much to ask for the amount of effort that goes into my tools. Of course, there's no reason you couldn't copy it from a friend but doing the right thing encourages and facilitates further developments.
Anyway, without further ado: Marmot Audio Shop
