i'm so glad deflemask has a hidden undocumented skip_intro feature in the config because i hate that stupid intro and software should not have intros with sound
i also hate how you can't set it to have a buffer of less than 512 (no unit mentioned) which still has latency in it and if you miss the options menu a bit too much to the right you hit the about button which wiggles a bitcoin donation qr code in your face until you can move your mouse to the tiny button on the middle of the screen to close it
basically deflemask's ux all comes across as very arrogant to me and i hate that i have no better option for pcengine music creation
