Undertale Boss Select

Adds a Bosses option to Undertale's main menu, right under Settings.

Pick a boss and you go straight into that fight, the real fight from your own copy of Undertale, with the LV, HP, weapon, armor and food a typical run has when it gets there:

• Napstablook, Toriel, Papyrus, Mad Dummy, Undyne, Muffet, Mettaton EX, Asgore, Photoshop Flowey and Asriel at LV 1, with the food you'd have picked up by then
• Undyne the Undying, Mettaton NEO and Sans (shown in red) as on the genocide route: LV 12, 15 and 19, with the gear and food from that route

Win or spare a boss and you're back on the list with a star next to their name and your personal best time for that boss. Lose and you're back on the list too, no save loading. Hold Backspace in a fight to give up.

Boss Rush runs every boss back to back on one HP bar: your HP carries over from fight to fight, while LV, gear and food switch to each boss's loadout. Your best Boss Rush time is saved.

Each boss's loadout is shown on the list before you fight.

Your save is safe: the mod plays from its own copy with its own save folder, so your normal Undertale save is never touched. Solo only.
