Package: libmupen64plus2
Version: 2.0-1
When upgrading libmupen64plus2 from 1.99.5-6 to 2.0-1, using 0-9 keys to
change save slot stopped working. The reason is that the version 2.0-1
uses SDL 2.0 and uses scancodes instead of keysyms to test for keys 0-9,
in the following way:
src/main/eventloop.c:457
else if (keysym >= SDL_SCANCODE_0 && keysym <= SDL_SCANCODE_9)
main_state_set_slot(keysym - SDL_SCANCODE_0);
Unfortunately, the values of scancodes for 0-9 are not sequential:
SDL2/SDL_scancode.h:81
SDL_SCANCODE_1 = 30,
SDL_SCANCODE_2 = 31,
SDL_SCANCODE_3 = 32,
SDL_SCANCODE_4 = 33,
SDL_SCANCODE_5 = 34,
SDL_SCANCODE_6 = 35,
SDL_SCANCODE_7 = 36,
SDL_SCANCODE_8 = 37,
SDL_SCANCODE_9 = 38,
SDL_SCANCODE_0 = 39,
Therefore, keysym is never >= SDL_SCANCODE_0 and <= SDL_SCANCODE_9.
According to SDL2 docs, "The values in this enumeration are based on the
USB usage page standard http://www.usb.org/developers/docs/";, so it is
probably safe to assume that they will not be changed and so
SDL_SCANCODE_1 to SDL_SCANCODE_9 are sequential, and test for
SDL_SCANCODE_0 separately.
