fastboot: skip intro/title/menu and autoload save if one exists
Three small hooks, all gated on CheckForPlayerNameInSRAM (carry = save present):
- home/init.asm: skip 'predef PlayIntro' when a save exists
- engine/movie/title.asm (PrepareTitleScreen): jp MainMenu, skipping the
title screen (only the boot path hits PrepareTitleScreen; return-to-title
paths jp DisplayTitleScreen directly, so they're unaffected)
- engine/menus/main_menu.asm (MainMenu): after TryLoadSaveFile, if
wSaveFileStatus==2 jp SpecialEnterMap, skipping the CONTINUE menu
Exported CheckForPlayerNameInSRAM (:: ) so home/init.asm can farcall it.
New game (no save) path is fully preserved. Ship pokeyellow.gbc only; the
_DEBUG build overflows home ROM0 by 8 bytes with the init hook.
