 GBDK-2020 gets support for SMS/GG targets

Hi!
I'm working on adding support for SMS and GG targets to GBDK-2020. Develop branch already contains crt, some minimal library (including console output) and toolchain, that supports compiling for SMS and GG, and also there are few cross-platform SMS/GG/GB examples. We also have GBDK-2020 support discord server, here is the invite link. I'm also looking forward for your suggestions and help. https://discord.gg/pg7YhK36 |

Amazing project!
I tried metasprites.sms and scroller.sms (the version posted here) and a_kanoid.sms (the version posted on discord) on real hardware (SMS1 FR Hang On with everdrive). metasprites.sms : perfect ! scroller.sms : scrolling text doesn't display at all, only text corner up left. a_kanoid.sms: seems like you're not cleaning the VRAM correctly, so lot of garbage depending of what was displayed before booting the game. To see what I'm talking about, fix the header/checksum for SMS, use Emulicous with a real BIOS (I personally use Hang On one). |

I ported "Black Castle", homebrew game by 0x7f. It works fine on GG, but even better on SMS because of scroll inhibit of the HUD.
Sources and rom can be found here: https://github.com/untoxa/BlackCastle No sound and music yet. Also missing flipped sprites. Work in progress.

made a sort of cross-platform "warcraft" prototype. select the actors and point their destination, they all may walk by their individual path at once.
