This version improves widescreen and extrawide versions:
- Fixes a missing S2 on default widescreen configuration. This should fix issues when playing the standard version on bsnes-hd and not getting the windowing mode correct.
- Upgrades the proximity patch to version 2.0, improving Mario <-> Enemy distance calculation.
- Adds detailed instructions and base patches for building SMW Widescreen from scratch. See BUILDING doc for more details.
Ultrawide version is still work in progress, but by following the building instructions you can see a preview version of it. Version 1.20 will release the definitive version, along with the 448x224 base patch.
