A simple search and replace patcher in PowerShell.
'?' in search patterns will match any nibble (half-byte).
'??' will match any byte.
Each patch definition can refer to multiple files and multiple search/replace patterns.
I wrote this because I wanted an easy way to share small binary patches without shipping a patcher that gets flagged as malware.
Notes:
- Requires PowerShell 5+
- Will load entire file into memory before patching
Patches are defined at the top of the script.
Like this:
$patches = @(
# example showing wildcard matches
[PatchInfo]@{
files = @("example\test.bin")
patterns = @("00 0? -> FFFF", "?C?C CC?? -> DEADFED5")
}
# example of patching multiple matches, and warning on not found
[PatchInfo]@{
files = @("example\test2.bin")
patterns = @("FFFF -> CC CC", "88 -> 99")
first_only = $false
warn_not_found = $true
}

Right-click and 'Run with PowerShell' to run.
