Anyone know how to use e-reader cards in Super Mario Advance 4?

[MathUser2929]

I want to use the card to add plants to SMB3. Using other cards would be nice too. I am talking about using the Visual Boy Advance emulator.

should have some useful information

Do you mean Super Mario Advance 4 - Super Mario Bros. 3? (that is to say the GBA port of SMB3; GBA Mario numbering gets confusing)

If so I should probably link https://gbatemp.net/threads/super-mario-advance-4-all-unreleased-e-reader-cards-translated.529179/ if so.

https://caitsith2.com/ereader/index.htm might also be of interest.

no-intro used to have a nice wiki as well but think it got lost in a site shuffle recently so might have to go on the wayback machine or something.

Some also fiddled with the wii u rerelease of the game as it included some things.

https://tcrf.net/Super_Mario_Advance_4:_Super_Mario_Bros._3#e-Reader_Support has a list of CodeBreaker codes for activating some e-reader effects, like adding the SMB2 plants.

I couldnt get it working, but does someone have the codebreaker codes they can post?

Ok, I found the plant code. It was at tcrf. I wish I could enable more of the e-cards, but at least I finally got the plant code working.

I have a copy of this with all levels unlocked. Sites refer to it as the "1.1" version but this is just code for "everything is unlocked".
