80010008 03000000 - Searches for 8 bytes of 03 00 00 00 05 00 01 00 once using Default Offset
05000100 00000000
92000000 00000DD1 - Adjusts the pointer offset by adding a value of 3537 dec = DD1 hex to the pointer
D8000000 020130FF - Tests and skips the following two code lines if 2 bytes from pointer equal `FF 30`
D8000000 0103C0FF - Tests and skips the following code line if 2 bytes from pointer equal less than `FF C0`
08000001 00000030 - Writes 1 byte with 1 offset from pointer, replacing a value less than `C0` with `30` (partial Isz glitch fix)

use conditional type inference to "copy" a type T into a new type variable O and then an identity-like mapped type which iterates through the copied type's properties.
