ES1 is implemented entirely in the front-end using features from GLES3.0. Therefore, every backend with GLES3 support (i.e. everything other than D3D9) supports GLES1 as well.
ANGLE passes GLES1's MustPass, however there are known missing features.
| Features | Status | Backends |
|---|---|---|
| Logic Op | Implemented through extensions 1 | Vulkan, GL |
| Palette compressed textures | Emulated with uncompressed format | Vulkan |
| Smooth lines | Unimplemented | None |
| Two-sided lighting | Unimplemented | None |
| Matrix palette | Unimplemented (optional) | None |
- Logic op is implemented through the
ANGLE_logic_oporEXT_framebuffer_fetchextensions. - Currently, these are supported on the Vulkan and GL backends only.
