This uses SDL and it sounds doable from a technical prospective.
However, the license it is under is overly broad :
In addition to the constraints set by the CC license, you must respect the following rules:
Do not offer the Software on a pay-per-play basis.
do not distribute the Software through pre-paid access websites or BBS's.
do not use the Software in publications of any form unless written consent is obtained by the author.
do not distribute the Software through mirror websites, unless written consent is obtained by the author.
do not distribute older versions of the Software through authorized mirror websites after newer ones have been made available by the author.
Even if i did a port, i can't even distribute it to you.
The cruel irony is that probably not even Nintendo's own EULA are this restrictive : I can still sell my physical Nintendo games thankfully.
What G&W games do you want to play ? Sounds like i can just redo them from scratch.
