Super Mario World - Just What Do I Need ROM

Super Mario World – Just What Do I Need is a 6-exit romhack of Super Mario Advance 2 (the GBA version of SMW) created using Smallhacker’s SMA2 transplant tool. Featuring a nonsensical blend of Standard, Kaizo, and Puzzle, this romhack heavily abuses the many strange and unusual additions that were added to the GBA version of this game. These include the ability to push Yoshi around without riding him, a revamped system for Special World color Yoshi spawning, and, of course, everyone’s favorite plumber with a hilariously floaty jump, Luigi.

There is a Player’s Guide section, which you will absolutely need to read before playing. This guide will go over the changes from SMW to SMA2 in great detail. Even with the help of the guide, you’ll encounter cryptic puzzles and some borderline Kaizo setups, so play at your own risk. If you get stuck, or if you’d rather just watch the hack instead of playing it, you can find a clear video here (major puzzle spoilers warning).

Players Guide

Changes from SMW to SMA2 (you WILL need to know these)

Mario and Luigi behave differently in a few different ways

• When Luigi is riding Yoshi, he can eat enemies and spit them back out again
• When Luigi hits a multi-coin ? block, all the coins spill out of it at once

Yoshi behaves quite differently from the SNES version

• You can “push” Yoshi along the ground by walking into him
• If you pass over Yoshi during the goal walk, Mario/Luigi will automatically hop back onto Yoshi
• Yoshi can safely “land” on certain platform sprites, such as grey platforms, rather than going straight through them like in SMW (note: red ? switches are an exception to this)
• Unlike the US SNES version, Yoshi can eat dolphins

Colored Yoshis also behave very differently

• Once you have fed and grown a special world color baby Yoshi for the first time, there is a chance that the special world baby Yoshi will spawn inside regular Yoshi ? blocks
• This depends on a few factors: if you’re small or big, it can be any colored Yoshi (this is entirely random)
•  If you’re cape, it will always be blue (if you’ve fed blue Yoshi already)
• If you’re fire flower, it will always be red (if you’ve fed red Yoshi already)
• Eating 10 berries with a special world color Yoshi results in an egg that hatches into a variety of powerups, rather than just a mushroom like in the SNES version
• Blue Yoshis hatch a cape
• Red Yoshis hatch a flower
