From a6ec18e23f88bd172aa3e13ed3081b3bf4e1996a Mon Sep 17 00:00:00 2001 From: Nebuleon Fumika Date: Mon, 14 Jan 2013 02:51:39 -0500 Subject: Preliminary support for saving to an arbitrary saved state slot. Currently, tapping a cell representing a saved state slot in the menu will load it, regardless of the current option, save or load. So the save option only accepts Left, Right and A. --- source/nds/gui.c | 228 +++++++++++++++++++++------------------------------ source/nds/message.h | 2 +- 2 files changed, 93 insertions(+), 137 deletions(-) (limited to 'source/nds') diff --git a/source/nds/gui.c b/source/nds/gui.c index 06a8500..934b254 100644 --- a/source/nds/gui.c +++ b/source/nds/gui.c @@ -77,8 +77,8 @@ EMU_CONFIG emu_config; GAME_CONFIG game_config; //save state file map -char savestate_map[SAVE_STATE_SLOT_NUM]; -static u32 savestate_index; +static u32 savestate_index; // current selection in the saved states menu +static u32 latest_save; // Slot number of the latest (in time) save for this game #define MAKE_MENU(name, init_function, passive_function, key_function, end_function, \ focus_option, screen_focus) \ @@ -282,8 +282,8 @@ u32 gamepad_config_menu; static void get_savestate_filelist(void); static FILE* get_savestate_snapshot(char *savestate_filename); static void get_savestate_filename(u32 slot, char *name_buffer); -static u32 get_savestate_slot(void); -static void reorder_savestate_slot(void); +static uint8 SavedStateSquareX (u32 slot); +static bool8 SavedStateFileExists (u32 slot); void get_newest_savestate(char *name_buffer); static int sort_function(const void *dest_str_ptr, const void *src_str_ptr); static u32 parse_line(char *current_line, char *current_str); @@ -1863,31 +1863,28 @@ u32 menu(u16 *screen) get_savestate_filename(slot_index, tmp_filename); sprintf(line_buffer, "%s/%s", DEFAULT_RTS_DIR, tmp_filename); remove(line_buffer); - if(savestate_map[slot_index] > 0) - savestate_map[slot_index]= -savestate_map[slot_index]; - reorder_savestate_slot(); } void savestate_selitem(u32 selected, u32 y_pos) { u32 k; - for(k= 0; k < 10; k++) //Only display 10 slot + for(k= 0; k < SAVE_STATE_SLOT_NUM; k++) { - if(selected != k) - { - if(savestate_map[k] > 0) //full - show_icon((unsigned short*)down_screen_addr, &ICON_NSTATEFULL, 28+k*21, y_pos); - else - show_icon((unsigned short*)down_screen_addr, &ICON_NSTATEEMPTY, 28+k*21, y_pos); - } - else //Highlight - { - if(savestate_map[k] > 0) //full - show_icon((unsigned short*)down_screen_addr, &ICON_STATEFULL, 28+k*21, y_pos); - else - show_icon((unsigned short*)down_screen_addr, &ICON_STATEEMPTY, 28+k*21, y_pos); - } + struct gui_iconlist *icon; + bool8 Exists = SavedStateFileExists (k); + uint8 X = SavedStateSquareX (k); + + if (selected == k && Exists) + icon = &ICON_STATEFULL; + else if (selected == k && !Exists) + icon = &ICON_STATEEMPTY; + else if (selected != k && Exists) + icon = &ICON_NSTATEFULL; + else if (selected != k && !Exists) + icon = &ICON_NSTATEEMPTY; + + show_icon((unsigned short *) down_screen_addr, icon, X, y_pos); } } @@ -1944,16 +1941,8 @@ u32 menu(u16 *screen) unsigned int selected; selected = -1; - //write save - slot_index= get_savestate_slot(); - sprintf(line_buffer, "%d", (slot_index+2) > SAVE_STATE_SLOT_NUM ?
