After extraction, your portable WinKawaks 1.65 folder should look like this:

WinKawaks_1.65_Portable/
├── winKawaks.exe          # Main emulator (portable)
├── ROMs/                  # All .zip ROM files go here
│   ├── kof97.zip
│   ├── mslug.zip
│   ├── sf2.zip
│   ├── neogeo.zip         # BIOS file (critical!)
│   └── ... (200+ ROMs)
├── Cheats/                # cheat.dat file
├── SaveStates/
├── Screenshots/
└── ini/                   # config files

Important: The file neogeo.zip (Neo-Geo BIOS) must be present in the ROMs folder. Without it, Neo-Geo games won’t boot.

If you are looking to relive the golden era of Neo-Geo and CPS1/CPS2 arcade games (Street Fighter, Metal Slug, Marvel vs. Capcom) without the hassle of configuring a modern frontend, this portable package is a fantastic find. However, it is strictly for older hardware and specific game libraries.

Do not download "installers" from scam sites. You want the 7-zip archived version.

A “full ROM set” is a complete collection of all games that the emulator can run. For WinKawaks 1.65, a full set typically includes:

A “full” set means no hunting for missing parent ROMs, BIOS files, or clone patches. Everything is pre-organized, CRC-checked, and ready to play.
