Possibility for a multi-directional scrolling platformer module?

[Dot_AO]

I was wondering if someone successfully made a platformer game in Nes Maker with both Horizontal and vertical scrolling? Or if someone have the knowledge to make one?
I was thinking of games like: Super Mario Bros 3 (when Mario goes high enough it loads screen above and you have the ability to backtrack to the left).
And Metroid (couple of screens it's vertical, you have a door, there's a transition until it loads the next sets of screens and then it became vertical).

vertical scrolling is at the top of many peoples wishlist, but it would be very difficult to implement with nesmaker, especially in a way that would work with most games. so no one has shared a way to do it yet. (and it is somewhat unlikely to happen soon)

Super Mario Bros. 3 and Metroid use a mapper (MMC3 & MMC1) that can switch its hardware scrolling direction during gameplay.
NESmaker games use Mapper 30, which allows only vertical or horizontal scrolling but cannot switch between them. Additionally, NESmaker (the engine) is designed only for horizontal scrolling (= vertical mirroring on Mapper 30) only!

Worse yet, the physical carts the homebrew scene uses are hardwired to either horizontal or vertical scrolling (there is a solder joint IIRC), with horizontal being the standard.

Some carts (like the INL ones) it's not hardwire, and the mirroring is set when the bcp is flashed. But basically, yes, you don't really have much choice here, NESmaker is meant for hozizontal scrolling only.
