The bootstrap code translates to the following ASM:
; Initial hl = D163
$D163 <- 05 || dec b
$D164 <- 24 || inc h ; h = D2
$D165 <- 2E ||
$D166 <- 22 || ld l, 22 ; hl = D222
$D167 <- 18 ||
$D168 <- 02 || jr
$D169 <- FF ||
$D16A <- FF ||
$D16B <- 24 || inc h ; h = D3
$D16C <- 00 || nop
$D16D <-
Understanding the ASM will allow modifying the setup to suit different needs. For example, to make 8F run code starting from item 1 ($D31E), replace the Onix (0x22) with a Tangela (0x1E).

Notice that this setup doesn't set hl to $D322, which some common item setups assume. For those item setups, inserting two items will fix this problem:
