Those games, as many other games on dreamcast hardware, require per-pixel alpha sorting (also know as OIT - order independent transparency, you can read more about it at https://www.libretro.com/index.php/flycast-is-getting-a-vulkan-renderer-available-later-today-on-retroarch-with-nightly-core/) to be rendered properly. It's unavailable with OpenGL ES and requires a fairly good gpu anyway (something those SoCs don't have).
