But have you seen the video of World-e? This video provides more evidence that Nintendo can hack Mario games better than anyone. We, the ROM hackers without association to Nintendo, have never produced anything like World-e in SMA4.
World-e refers to new levels in SMA4 and not from SMB3. To play them, you must scan their e-Reader cards to unlock them. (This requires two Game Boy Advances, an e-Reader, a GBA link cable and a SMA4 cartridge; or an emulation of all this.) Japan has all cards, America has some cards, Europe has no cards.
- several powerups and sprites from Super Mario Advance 2 (GBA), including the Cape Feather, the 3-up moon, the carryable springboard, the Chargin' Chuck, the Monty Mole, the Wriggler, the L'il Sparky, the Hothead, the carryable and parachuting Goombas, and more.
- the triangle blocks from SMA2, plus new flipped triangle blocks that allow Mario to run on the ceiling.
- a few more imports like the veggies from Super Mario Advance (GBA) and the Bumpty from Super Mario Advance 3 (GBA).
- some more stuff in the video.
The current theory is that the level data is in the e-Reader cards, but the new features like the sprites are in the ROM of SMA4. Hackers might use the Monty Mole and the other stuff in the ROM, without using the e-Reader cards.
We put events in order.
- Nintendo created Super Mario Bros. 3 (NES).
- Nintendo hacked SMB3 to make Super Mario World (SNES).
- Nintendo ported SMB3 to make part of Super Mario All-Stars (SNES), this is SMAS.
- Nintendo ported SMW to make Super Mario Advance 2 (SMW), this is SMA2.
SMB3 and SMW use similar engines. Nintendo might have used the engine of SMA2 as the base hack for SMA4; this would explain certain SMA2 features in the SMA4 engine. The levels and graphics in SMA4 come from SMAS. So SMA4 might be a hybrid hack of SMA2 and SMAS; this is how World-e of SMA4 has so much from SMW or SMA2.
We might want to make ROM hacks from SMA4, because SMA4 has so much in one ROM.
