MSXはアンドロイドの夢を見るか９

IS01のキーボードが正常に認識しない問題ですが、まずはSDLの仕様で「/」が認識しないため以下を修正。

SDL_androidkeyboard.c

static SDL_scancode
TranslateKeycode(int keycode)
{
    SDL_scancode scancode = SDL_SCANCODE_UNKNOWN;

    if (keycode < SDL_arraysize(Android_Keycodes)) {
        scancode = Android_Keycodes[keycode];
    }
    if (scancode == SDL_SCANCODE_UNKNOWN) {
	return SDL_SCANCODE_SLASH;
    }
    return scancode;
}

また、IS01の仕様で特殊キーや、足りないキーに対応する。具体的には「Alt」で切り替える。

SDLgfx.c

#include <SDL.h>

#ifdef _IS01
static int alt=0;
#endif
