NTRQ is free to use and always will be.
However, if you think it’s worth paying something for then please consider visiting the link below and making a donation.
I’ve set up a link to make donations to Cancer Research. My mum has been battling cancer for the past 3 years and wouldn’t be here today if it wasn’t for the people dedicating their lives to helping us all fight this terrible disease. This is my way of saying thanks.
The more donations received, the more I’ll be encouraged to continue developing NES audio software.
