Dude you rock, and so do the other people who've helped you out. I just played through the hack and can say i honestly had a blast. I left reviews on the base hack pages of mOTHER+99 and mOTHER as i think it's an essential add on to the great work done by those folks. https://www.romhacking.net/hacks/3640/
I had no major issues to report but i will say Ridley's flickering was the most notable issue, but i suppose that's just the reality of the NES. Hopefully this gets more recognition going forward as i feel it really deserves it but more than anything i just wanted to say thanks, it's very kind and awesome of you to do this work and put it out there so people like me can enjoy it.
