Export to old systems

Could GDEV export for older systems like the mighty Amiga, ZX Spectrum, etc?. GDEV is such a cool engine and the ability to export games for older systems would be incredible.
How hard would it be to do such a thing?

Unfortunately, Near impossible as those systems do not support the programming language used, nor the rendering methods uses by PixiJS, the renderer used by the engine.

(Note, not impossible, just extremely difficult.)
