What is ORCA

A tool to merge MAME ROMs using recipes (.xml or .mra) into a single .rom file to be used with an Arcade gateware IP Core.

Installation

To set up ORCA, you only need to:

• Download the latest release
  • Debian/Ubuntu and WSL users can download the .deb package and install using sudo dpkg -i ORCA-<version>-Linux.deb
• Extract the executable to a directory in your PATH System Variable. e.g: /usr/bin on macOS/Linux or %WINDIR% on Windows

Usage

Single File

# Linux/macOS
orca -z /PATH/TO/MAME/ZIPS file.[xml/mra]

# Windows
orca.exe -z DRIVE:\PATH\TO\MAME\ZIPS file.[xml/mra]

Batch processing using scripts

Assuming you have the following structure

.
├── output
├── roms
├── tools
│   └── make_roms.[sh/ps1]
└── xml

On Linux/WSL and macOS:

Note: Change the PATHs according to your needs

#!/usr/bin/env bash

PARENT=$(dirname $PWD)
XML=$PARENT/xml
ROMS=$PARENT/roms
ASSETS=$PARENT/output

find ${XML} -name '*.xml' | while read line; do
    echo "Processing '$line'"
    orca -z ${ROMS} -O ${ASSETS} "$line"
done

Windows Powershell:

$currentPath = $(Get-Item $($MyInvocation.MyCommand.Path)).DirectoryName
$fileNames = Get-ChildItem -Path "$currentPath\..\xml" -Recurse -Include *.xml

try { 
    foreach ($f in $fileNames){
        $xmlfile = $f.FullName
        Write-Host "Processing $xmlfile ..."
        orca.exe -z ..\roms -O ..\output $xmlfile
    }
} catch {
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
} finally {
    Write-Host "Done."
    timeout /t 5
}

exit 0

Output:

PS A:\rom-recipes\tools> .\make_roms.ps1
Processing A:\recipes\xml\Recipe.xml ...
Done.
