nostalgic-css / NES.css

$cursor-url: url(get-file-as-data-uri("../assets/cursor.png")) !default;

Describe the bug

When I try to use a custom theme

To Reproduce

// xx.scss
$primary-colors: (
  normal: red,
  hover: red,
  shadow: red,
) !default;

@import "nes.css/scss/nes.scss";

Expected behavior

Environment:

Suggestion(s) for fixing this issue
In my opinion, should we not rely on the JS transformation Base64, but use the transformation directly?，Is it possible to provide the ability to customize the theme。

Additional context
In the component library I'm developing, I'm trying to provide a set of custom themes

Same issue, I'm trying to alter the success color to a brighter green but to no avail. When I import variables like this:
@import "node_modules/nes.css/scss/base/variables";
it gives me this error in compilation:

HookWebpackError: Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
SassError: Undefined variable.
