Oh shi- plothole... Well, the Yoshi Heartland is where Yoshis *truly* come from, so Yoshi's island is a place they later colonised. Besides, all the mario games have plotholes anyway. Just pretend that this explanation is canon (or fanon).
Edit: BTW, this isn't the forest tileset, and I don't plan to ExGFX my own tree trunks. Also, "Yoshi Bush" sounds stupider in my opinion than "Yoshi Forest". So, probably not.
Well, I've seen youtoobs of Kaiso mario world 1, and I found the link to no. 2 in SA forums. In 2, I've finished 2 levels.
Fu-damn, you know how hard hacks are frustrating? Kaiso mario world is so hard that it goes beyond frustration - I'm just happy to be alive after 50 savestate attempts.
Well, my vote for a base hack section is "yes" because it would be useful to differentiate them from other hacks. I still prefer for everyone to make their own stuff, but since others usually don't... then fine.
