F18a functionality

[wiesl]

Hello,

Nice project in combination with pico9918.

Any plans to implement F18a functionality?

Thanks.

I do plan on adding V9938, V9958 and F18A support in the future. I'd like to keep this library as clean/minimal as possible though, so I'm not sure how that will look at this stage. Possibly separate libraries.

F18A is now implemented in the pico9918 and gpu-dev branches, but it is very Pico-specific, so leaving this issue open until I produce a platform-independent implementation. I might do this, because otherwise I can't add F18A features to my HBC-56 emulator :)
