sdlarch's Issues

NDI idea

First of all. Great work.
Wait you seems to understand portuguese :)
So, here it goes:
Vi que possui dois projetos: nanoarch e sdlarch que são similares.
A ideia seria, abstrair a saída gráfica e sonora utilizando NDI.
Já que existe o núcleo libretro-ffmeg que poderia ser compilado com suporte a Network Device Interface.
Com isso, "em teoria", poderia fazer streaming de qualquer jogo suportado por libretro para qualquer dispositivo sem a necessidade da camada gráfica/sonora em sdl2 ou glfw. Imagino que para o joystick ainda seria necessário.
Os clientes VLC e OBS parecem já suportar.
Tive essa ideia, enquanto ouvia o criador Andrew comentando sobre o protocolo.
Enfim, vou fazer um fork do projeto e tentar implementar também.

OpenGL Sample

When running through the following OpenGL sample:
https://github.com/libretro/libretro-samples/tree/master/video/opengl/libretro_test_gl_fixedfunction

I get the following:

Failed to create OpenGL context: Could not create GL context: BadMatch (invalid parameter attributes)

It works through RetroArch though, know what I'm missing?

Crash if a directory name is passed as game

It appears that -1 is assigned as file size at

sdlarch/sdlarch.c

Line 700 in 10a9ffd

info.size = SDL_RWsize(file);

A crash follows after trying to allocate a buffer of (size_t)-1 bytes

Perf interface for Timers

RETRO_ENVIRONMENT_GET_PERF_INTERFACE

We could adapt it around SDL_GetTicks().

Support for non-emulator cores / RETRO_ENVIRONMENT_SET_SUPPORT_NO_GAME

A libretro core can declare

bool no_game = true;
env_cb(RETRO_ENVIRONMENT_SET_SUPPORT_NO_GAME, &no_game);

In that case, it should be possible to run the core without specifying a game.

However, sdlarch refuses to launch with just one argument (usage: sdlarch <core> <game>)

Mupen64 Desynced Audio

Running Mario Kart 64, getting desynced audio.

Audio Callback

Implement definition for RETRO_ENVIRONMENT_SET_AUDIO_CALLBACK.
