Adding smb3 all stars support

[city41]

I've been mulling this over in the back of my head. What if smaghetti could also build levels for SNES all stars smb3?

• the same graphics/resources used by smaghetti today could be reused in allstars mode. ie goomba looks and behaves the same in both games, as does pretty much everything else
• the editor itself would still be used pretty much exactly as is, only real difference is the viewport grid would change size
• entities can have an optional allstars config that allows the editor and createLevelData to use them seamlessly in allstar mode. From createLevelData and the editor's point of view, nothing really changes, just the entities get reconfigured behind the scenes. So in sma4 mode, goomba might emit one set of binary data and also declare a certain compatibility, and in allstar mode it might emit slightly different binary data and possibly have different compatibility. The editor just consumes this info and presents it to the user as it does today.
• entities that are not in allstars (say buried vegetable, flutter, etc) would just get disabled in allstar mode and the key for determining that is they'd just lack an allstars config.

if were to pursue this, I think the right steps would be

• add support for built in SMA4 levels to hex-tree
• leverage that new support to then add allstar support to hex-tree
• grab a handful of entities, say brick, coin and goomba, and give them the allstars config as guinea pigs
• have createLevelData emit an allstars level
• add a new component that takes that level and converts it into an ips patch, most likely just replacing 1-1 with the new level.
• patch an allstars rom and try the level

Probably the biggest challenge is adding a snes emulator that works in the browser. Not technically required at least as long as this is just an experiment. Could probably find ways to get a decent feedback loop without a snes emulator built in.

Also I think the hex-tree steps above would only be needed if pursuing a full allstars mode. For the guinea pig experiment, a regular hex editor should suffice

I am closing this discussion as I have decided I will pursue this. I plan to start working on this in November. For further discussion, see the issue
