Solution to XD VA GD KHT BD

As the flavortext tells you, this puzzle does not require translating anything from Korean. (Indeed, pasting the Korean part of the flavortext into Google Translate informs you that Google Translate won't help, either.) The puzzle is actually an English-language crossword whose clues have been phonetically transliterated (not translated!) into Hangul, the Korean script. Google text-to-speech can pronounce the clues for you if you don't read Hangul, and using it on the clue headings tells you that they are 아크로스 ("ah kə roh sə") and 다운 ("dah oon"), which should be a big hint as to what's going on. But you should probably also learn some things about Hangul to solve the puzzle. Some relevant facts:

1. Hangul is alphabetic, with 14 consonants and 10 vowels.
2. Hangul text is arranged into blocks of one syllable each, read from left to right. Every syllable starts with a consonant, then has one vowel either below or to the right of that consonant (vowels whose long stroke is horizontal go below, and vowels whose long stroke is vertical go to the right), and optionally can also have an ending consonant at the bottom of the block.
3. Diphthongs exist; most of them are pronounced by just pronouncing the individual vowel sounds in order, but a notable exception is ㅐ/ ㅔ, both of which are pronounced like a short e sound (as in bet or head). In modern Korean as spoken in South Korea, the two spellings are pronounced exactly the same. (North Koreans and some older South Koreans claim that there is a subtle difference between them, but if there is, neither of the two authors of this puzzle can hear it.)
4. A few consonants differ quite a bit in their pronunciation depending on whether they are found at the start or end of a syllable. Most importantly, the consonant ㅇ is silent at the start of a syllable (and is used as a placeholder for syllables that phonetically begin with a vowel sound), but pronounced like -ng at the end of a syllable. Also, the consonant ㄹ is both L and R; it sounds more like an R at the start of a syllable and L at the end. (An L in the middle of a word, even if it begins a syllable, can be approximated by adding an L to the end of the previous syllable, but an L at the start of a word just doesn't exist in Korean.)
5. There are other phonemes common in English that don't exist at all in Korean, so transliterating requires you to just make a somewhat close substitution. Examples include z (for which ㅈ, the j-like consonant, is typically used), f and v (ㅍ/ㅂ, p-like and b-like respectively). Neither the voiced or unvoiced th sound exists either; voiced th (as in the) is typically treated like a d sound, and unvoiced (as in thin) like an s.
6. Consonant clusters are difficult to render in Korean; generally, they need to get expanded into multiple syllables so that each of the consonant sounds can be heard. Most commonly this is done by attaching the schwa-like vowel ㅡ to each of the non-syllable consonants.

So you can start to fill in the grid using Google text-to-speech, but you will quickly notice that most of the clues are incomplete in Hangul; they contain some capital letters from the Roman alphabet that resemble some kind of cipher. Indeed, they are a cipher—each of those letters stands for a different Hangul letter. It's possible to crack the cipher yourself by making good educated guesses as to some of the ciphered words, but it will help immensely as soon as you can fill in the entry at 74-across, SKATS, and then Google it. SKATS is a Hangul romanization cipher based on Korean Morse code, and it's been used to encipher many of the words in the clues.

Some things that will help you piece the clues together:

1. All punctuation and spaces in the clues have been preserved. In particular, pay attention to the spaces between blocks in Hangul, as they tell you where the word breaks are in the clue.
2. In SKATS, syllable blocks are separated by a single space, and word breaks are indicated by a double space. The SKATS words in the clues adhere to this convention.
3. Only entire words (as opposed to individual syllables within words) have been enciphered in SKATS.
4. Several of the clues refer to Korean food and culture, so there are a handful of places where the Hangul or SKATS words don't sound like English, because they're not. They're the name of a Korean celebrity, or a Korean food or drink.
5. The title of the puzzle is SKATS for 크로스워드, which is just "Crossword". (You don't need to decipher it, but it's there.)

Filling out the grid reveals the eight-part instruction at 19-, 25-, 29-, 39-, 49-, 50-, 62-, and 74-across: SHADE IN / EVERY / ENTRY / WITH A LETTER / THAT / ALSO / IS USED IN ITS CLUE IN / SKATS. Doing so gives you this grid:

The shading forms the Hangul text 고돔도. That doesn't mean anything in either Korean or English, but enciphering it in SKATS gives LA BAMBA, which is the answer.
