[Emu fork] lr-atari800 with fixed keyboard & 4 controllers

rkoster

I found and fixed the bug that prevented typing any characters that needed the SHIFT or CTRL keys. This also opened up lowercase typing, because you can now unlock CAPSLOCK.

~~There's a pull request for libretro/lr-atari800. But that hasn't been touched in 10 months, so I don't know when they'll pick it up.~~

~~If anyone wants to build my version because they urgently need the fix, it's at https://github.com/raphkoster/libretro-atari800~~

This has been merged upstream, so getting my fork is no longer needed.

I needed to play M.U.L.E. as it should be played, so... I have added support for four joysticks to my fork of lr-atari800 core.

To take advantage of this, you just need to set the emulated machine to "Atari 400/800" under Options. The other machine types only had two joystick ports. Be sure to remember to set the two additional joysticks to Atari Joystick, rather than RetroPad.

Just as before, the additional special hotkeys (Select, Option, virtual keyboard, etc) only work on the first controller.

Have the changes been submitted upstream? Would be good to have them in the main core. Thanks.

I submitted a pull request for the keyboard fix a while back (https://github.com/libretro/libretro-atari800/pull/27). That said, it doesn't look like any attention has been paid to the core upstream in many months.

The controller changes are brand new and a bit more extensive, so I'd rather see them get tried out a bit before submitting a pull request.

The keyboard fix and the four controller fix have been merged upstream by the Retroarch folks!
