You might be right, but I still want the option to use the original sound effects. I cannot say which I will prefer until I try them both. It should be very easy to simply make two .ips patches available. Please do that.
He is right.
But, you know what? It doesn't matter if he's right or not. It's their project. They are the creators, and the result of whatever they choose to include in the game is their intention. What you "will prefer" is not a factor that should be taken into consideration on any level. What "the creators prefer" is the only thing that needs to be considered.
You aren't in a position to special order it. You are in the position to play it -or not- and are being extremely disrespectful by posting with such a sense of entitlement that creators should cater to you like they're taking your Burger King order.
Sometimes folks around here seem to need a reminder that the work people do here, they do for free. They take away time from their families, their other hobbies, etc. to make these projects -unpaid- and then release them for free.
I appreciate your contributions to the retro gaming scene through your blogs, videos, etc. but you seriously need to step back a second and realize what you are doing and the effect it has on others, in particular those few who are actually producing new content for said scene.
