Code language for porting games to other engines

[Xuwboss]

This probably isn't the right spot for it but i was wondering something.
Say i had 100% original graphics(Since the RTP and DLC's can only be used in RPG Maker software) and wanted to expand my game so i can get my game console ready. What language would be suitable to do this? and does anyone know of anyone that has attempted this?

I was curious because of Undertale's expected Physical Release after it came out on consoles and the game was made with GameMaker: Studio

You can only deploy MV games to systems that support HTML5 games and JavaScript.
If a device does not support that, forget about converting your games for it.

Additionally, consoles like Xbox or PlayStation or so requires you to purchase developer access and it is extremely unlikely that there will ever be a way to deploy there.
