libretro port

[eadmaster]

don't port this to Windows, port it to the libretro core as a core option (automatically support a lot more platforms)

Now that the wide_gb library does compile on Windows, this should be more feasible.

Would very much enjoy this seeing currently there is not support for linux users

do we have a followup on this?

[kemenaran]

Hey, thanks for asking! To be fair, the development of the Windows version was quite tiresome (for a lack of a proper Windows development environment on my side), so I stopped working on this project for now.

However compiling the SameBoy libretro port from the current code shouldn't be too hard. If someone wants to try, I can definitely provide some mentoring.

Also, I opened #6 to improve the scene change heuristic (which for now is quite a limitation of WideGB). Again, I can mentor someone wanting to have a look at this.
