I have no idea if there is a code like that, but the three codes im posting, will allow you to build a pmn ladder. I will also post the anti 35 i have [it works] that helps with banns and other codes. Have the anti-35 code on at all times.

#DMA ANTI-35 [NO BAN]
0xFFFFFFFF 0x004C6614
0x00007EFC 0x00000000

#explosions off(1.6)no35
;binary port
0x0031386C 0x30C60000

#PMN TOWER (NO 35)
0x005FE4C0 0x00000001
0x005FE4E8 0x00000000
0x005FE538 0x05580558
0x005FE53C 0x001409C8

#Infinite Ammo
;Cheat Hz 15/1000
0xFFFFFFFF 0x00600630
0x00000014 0x00003008

Have these codes on and you can build pmn towers easily.
