'''NOTE:''' This is for English Pokémon Yellow only.
Naturally, only 56 trainers can be encountered via the trainer escape glitch (Special stats of 200-255, trainer IDs 0 to 55).

However, with arbitrary code execution, you can encounter artificial trainer classes with the routine at 3D:5FF2 with these very specific items:
1. ws m (0x63), any
2. 4F (0x59), any
3. Lemonade (0x3E), x61
4. Thunderstone (0x21), x242
5. 10F (0x5F), x1
6. X-Special (0x44), x2
7. Max Potion (0x11), x127
8. TM18 (0xDA), x205
9. Item 0x9D, x0
10. TM01 (0xC9), x33
11. Item 0xBB, x218
12. Lemonade (0x3E), x62
13. Water Stone (0x22), x4
14. Lemonade (0x3E), x(class)
15. Water Stone (0x22), x4
16. Lemonade (0x3E), x255
17. TM34 (0xEA), x88
18. TM08 (0xD0), x4
19. Poké Ball (0x04), x6
20. Soda Pop (0x3D), x33
21. Item 0x7F, x218
22. TM05 (0xCD), x132
23. Lemonade (0x3E), x201

Before you use ws m and 4F, make sure the bytes (C3, 21, D3) are located at DA7F and the bytes (C3 30 D3) are at DA64 (FA64).

Code:
For "ws m" (0x63):
- ld a, 3D
- ld hl, 5FF2
- ld bc, 0244
- ld de, DA7F
- call 009D
- ret
<nowiki><br></nowiki>
This code calls "FarCopyData" with its source being 3D:5FF2, the bytes to copy being 0x244, and the destination as DA7F.

For "4F" (0x59):
- ld hl, DABB
- ld a, 3E
- ldi (hl), a
- inc b
- ld a, (class)
- ldi (hl), a
- inc b
- ld a, FF
- ld (D058), a
- inc b
- inc b
- ld b, 3D
- ld hl, DA7F
- call 3E84
- ret
