Alternative Genesis Core with ARM support.

From the comment in SDL_filesystem.h:
Please call SDL_free() on the pointer when you are done with it

When building the project with MSVC, I ran into some debug heap asserts early into the program startup.
The culprit appears to be the code in m_config.c that does free(prefdir) as changing these to SDL_free(prefdir) resolved the issue.

I'm not sure what to do about `GetDefaultConfi

Via playtesting, the compass arrows (#29) were ignored, likely because they are right at the edge and outside the player's attention. If they are moved slightly inwards, they may become more noticeable.

Games that have these arrows also tend to draw them closer to the player rather than near the edge; e.g.

• GTA 1 & 2
• Fire Fight
• Crazy Taxi

Spelling of the word "viewport" is inconsistent in the code, sometimes it's spelled viewPort and sometimes viewport. It would be nice to make it consistent.

The font bitmap has empty space reserved for ASCII characters 0x80 through 0xA0.

We should use that space for something, like icons for WASM-4 controller buttons, or generic sprites like stars/hearts/etc.

Games can then use hex string literals to easily display these:

text("Press \x80 to jump!", 0, 0);
