Secret Maryo Chronicles AKA Super Mario Clone FX / SMC

I've searched for nearly two days so far, and unfortunately haven't found any version that early of SMC.  On the two pages you linked, after looking at the Page Source on each, the files themselves were not archived, so they aren't there on either page.  So, unfortunately, those routes are dead ends for finding any of the versions you're looking for.

However, I did find something interesting on the Internet Archive.  First:

This was uploaded on June 1st, is labeled as a port of version 0.97 for the Sony PSP, and according to the poster, it seems to be the earliest version found online.   I couldn't get it to work on any PSP emulator I tried it on, unfortunately, and my PSP is buried in a bunch of other stuff right now, and I don't know exactly where it is, so I can't used the included instructions to transfer it to that and see if it works.  Then, I also found this:

These were uploaded on May 31st and (obviously) labeled as early tech demos of SMC.  There's no version numbers anywhere, and they're for some reason saved in .cdi format, which is the format used for Dreamcast games.  I used ReDream Dreamcast Emulator to play them, and they worked just fine.  I couldn't find any more information on them at all, and have no idea if they're legitimate early tech demos that were made by the team behind SMC or not.  They do seem to use early sprites that were shown on the original website and much of other artwork and screenshots from around that time, however, so it's at least possible.  Again, there's absolutely nothing about them online that I could find, except for the posts on Internet Archive; there are two more posts there, with one having only one of the demos, and the other only being a torrent download for the same 3 files that are on the IA page to which I linked.

That's all I've been able to find thus far.  As far as I can tell, they're not what you were looking for, but I'd think are interesting and a step in the right direction, at least.  I've got a couple more ideas as to places to look, and when I have the time over the next few days I'll see what I can come up with.
