I respect your effort - it's good for what it is, essentially being an easy mode.
But for someone like me who enjoys the challenge of the original it makes the games too easy, since enemies still move at a regular speed. I also prefer to have weapon downgrades intact and I'm rather fond of the original power-up icons.
edit: Just played through your hack again and in addition to what I wrote before I'd also like to add that I feel it makes the player character actually move a bit too fast (personally I feel like Belmont's Revenge had the perfect amount of speed). And while for the most part the added velocity makes things easier it also makes some jumps actually more difficult, since it's more likely to jump too far now, to "overshoot" so to speak. I appreciate the effort making the items look more in line with the rest of the series, but the redesigns lack clarity, especially when played on a smaller screen. The original designs on the other hand were nice, clear and distinct.
I hope you don't take this criticism the wrong way, since the hack works pretty well for the most part and I could see it making the game more enjoyable to some people. And the fact alone that you even bothered to make a hack for this "black sheep" game is very much appreciated. It's just not quite what I'm looking for.
