FEATURE - Use bottom screen as map per DS

[mkst]

Intro

The DS version of SM64 used the bottom screen for a map (as well as other HUD (HDD?) elements). Rather than having a blank screen, or configuration, we could/should leverage the bottom screen for a map in the 3DS port too.

Considerations

Any assets being distributed as part of the repo need to be free from (Nintendo) copyright. If we wish to use any sprites/assets from either N64 or DS versions they should be extracted from the ROM at compile-time.

TBD: are Blender exports of levels subject to copyright?

Progress:

Versions:

There are a couple ways to do this, lets call them "1.0" and "2.0". Ideally lessons learnt doing 1.0 will transfer to 2.0

1.0

This is the 'lets just get something working' version

• [x] Draw the correct background based on the current level being played
• [x] Draw the correct background based on the current AREA of the level being played
• [x] Determine Mario's X/Y world position and map (via scale/offset) into 0-256 and 0-256 coords
• [x] Overlay some kind of 'red dot' for Mario's position
• [x] Sprite for Mario rather than square
• [x] Background colour to fill transparent areas per DS version
• [x] Display arrow for direction Mario is facing

2.0

• [ ] Use higher resolution png (512x512? 1024x1024? e.g, tile 4x 256x256 to make a 512x512 map)
• [ ] TOGGLE: Rotate map based on Mario's direction (Mario always at origin 0,0, (or 160,120 - i.e. centre of the screen))
• [ ] Zoom png based on user input?
• [ ] Overlay assets, stars? other points of interest?
• [ ] Change minimap based on x/y/z location of Mario e.g. Castle and BBH, levels with multiple vertical levels.

Zoom feature could come handy since, using SM64DS Editor, you can render all objects/enemies of the field on a map. I would be an useful map-guide feature.
