Thanks for comming back and uploading the file again. I kept this bookmarked to check on it later in case it got more progress over time, but when I came back to it the link was down. I'll check it out soon.
It's sad to see one of the rare Mega Man X hacks pushing things forward abandoned, I was very excited to see game's enemies implemented. But it's also very understandable under these circumstances. Thanks for sharing!
