Understanding the files on the DVD of Arirang Karaoke (hk2 & midi0)

[Ishisashi]

Since the most-significant byte of length info are likely to be 0, it is possible to find the mask itself from the length info?

38 03 03 34 36 2E 31 30 2E 30 2E 4E 2C 46 6E 2C 42 6E 0E 09 23 53 4A 53 46 23 4F 4A 4D 46 0E 09 0E 09 0E 09 0E 09 23 23 23 23 23 23 23 23 23 23 23 4A 6D 70 77 71 76 6E 66 77 62

From the third byte (little-endian integer), it can be seen that the mask is 0x03.

Disc B MUN99603.DAT
I manually identified the offsets and masks for the first 15 songs based on this idea.

|Kumyoung no.|Title|Offset|Mask|
|-|-|-|-|
|124|결혼 행진곡 (신부 입장)|0xE7000|0x00|
|550|애 국 가(1절)|0xEA000|0x5A|
|564|어머니의 마음|0xEF000|0x48|
|931|LAST CHRISTMAS|0xF9800|0x59|
|1000|졸업식 노래|0x10F000|0x18|
|1024|어린이날 노래|0x115000|0x00|
|1025|어머님 은혜|0x119000|0x7B|
|1051|ADORO|0x166800|0x61|
|1052|All For The Love Of A Girl|0x171800|0x60|
|1053|AND I LOVE HER|0x179000|0x63|
|1054|As tears go by|0x183000|0x62|
|1055|Autumn Leaves|0x21F800|0x61|
|1056|Bad Case Of Loving You|0x362800|0x60|
|1057|Before The Dawn|0x510000|0x5B|
|1058|Bridge Over Troubled Water|0x516800|0x5A|

The current issue is, where are the offsets and masks stored?

Is anyone still actively working on extracting the midi part?
I can get the title and lyrics and mp3. But cannot get anything on the midi part.

Henry123 mentioned he can get all the midis. I wonder if anyone know how to do it, please share the knowledge. Thanks in advance

Good work! Please share your codes and let others benefit from that.

My plan is trying to get AI to help. But without a player I don't think I have a chance. It's a complex matter. It's hard to work alone therefore this discussion group. Please share your results for discussion.
