Make your own *.ptn

1. Convert *.ptn to *.bms

Step 1.

1. Open your *.ptn file in hex editor (Anything else).

2. Find the first EZTR text (in hex, 45 5A 54 52).

3. Copy

   50 54 46 46 00 06 C0 00 0D 00 0A 43 40 00 A0 3E 00 00 8E 37 11 43 F9 00 01 01 30 2D 61 69 2E 6F 67 67 00 00 41 00 49 00 88 65 47 00 50 65 A6 00 A0 B1 A6 00 9C F6 12 00 70 A1 41 00 C0 F7 12 00 D8 F8 45 00 00 00 00 00 C0 F7 12 00 18 F9 12 00 C1 5C 41 00 C0 F7 12 00 D8 F8 02 00 32 2D 63 6C 61 70 2D 30 31 2E 6F 67 67 00 88 65 47 00 50 65 A6 00 A0 B1 A6 00 9C F6 12 00 70 A1 41 00 C0 F7 12 00 D8 F8 45 00 00 00 00 00 C0 F7 12 00 18 F9 12 00 C1 5C 41 00 C0 F7 12 00 D8 F8

   This is temporary header data.

4. and paste this before the first EZTR text (in hex, 45 5A 54 52).

5. Cut last N-number of EZTR datas (include EZTR text) which have not null datas.

   Example:

   If you want to make 5 Line pattern, Cut last 5 EZTR datas which have not null datas.

6. Find the fourth EZTR text, and paste at front of the fourth EZTR text.

   Example:

   (Copied hexes) 45 5A 54 52 (Some hexes)

7. Save it.

Step 2.

1. By using ptfluffy(pt2bms), Make *.ptn to *.bms (It can need to change extension to *.pt)
2. Open your *.bms by BMSE.
3. Change yours.
4. Select All notes by Ctrl-A and Copy it Ctrl-C.
5. Paste it at Notepad, save it, name it "input.txt". This is BMSE ClipBoard Object Data Format.

2. Convert BMS Data to *.ptn Hex Data

1. *.ptn files have In-Game Note datas. Each have 11 byte data.

2. It can make by bms2hex.

   2.1 Usage bms2hex

   python3 bms2hex.py

3. Done !

3. Paste Hex Data to *.ptn

1. Output data have several tracks. Track #011 ~ #019 will be key part.

2. Copy each tracks. If you made 5 Line pattern, Copy #011 ~ #015.

3. Referencing song's original *.ptn, Replace data at last 5 EZTRs.

   Example:

   If you made 5 Line pattern, find last 5 EZTRs. Each EZTRs are 1 Line.
   #011 Track will be Line 1, #012 Track will be Line 2.... (#012 also can be Line 1)
   Start by EZTR text, 75~78th bytes mean length of 1 Line note data.
   Change it (output.txt has length data).
   After length bytes, Replace your own hex datas.
   Repeat this.
