ExtraPulp is a Chrome extension that unlocks PlayDate Pulp’s hidden 16x16 tile mode, so you can make games at the PlayDate’s native 400x240 resolution instead of the normal 200x120.
To install, download the source and follow Chrome’s instructions for loading an unpacked extension.
The Pulp editor actually supports configuring the tile size and scale factor in the source code:
var tileWidth = 8; var tileHeight = 8; var editorScale = 2; // TODO: remove me, we're not supporting this, it gets too hairy
It looks like full resolution support was planned during development, but removed. This extension simply forces tileWidth and tileHeight to 16, and editorScale to 1.
