Yoshi's Story GBA tech demo - very fangame looking?

[DJ Yoshiman]

@DJ Yoshiman Holy Yoshi, it's the Yoshiman himself! I mean, I was half-expecting you to show up, but I still gasped when I saw your name by this thread in the index page! Haha, I suppose that the tech demo isn't weird enough to scream "young Yoshiman"! If you did make it back then, it would be more like the unfinished Yoshiman level in Yoshi Gone MFGG! Like, there's no mutant Koopa Troopa with a Goomba head in the tech demo, but there sure is one walking around in your level!

It's pretty cool to hear about the extension! Do you remember what it was called, and where you got it from? I found not one, but two lists of TGF/CNC extensions (albeit most extensions are shared between), but from what I can see there doesn't seem to be an extension that does magic with transitions.

You know what, thinking back on it now, I think Yoshi RPG was a MMF game. If it only has an exe, that would confirm it.
Just checked, yep, exe only, it's a MMF game. The zooming transitions are built-in as of 1.5, I believe.
