A “full set” refers to a complete collection of ROMs that are compatible with a specific emulator version. For WinKawaks, a full set includes:
The number varies, but a true WinKawaks full set typically contains 400–600+ zip files, roughly 5–10 GB compressed.
Open WinKawaks. Go to File > Load Game. Click Audit All Games. winkawaks full set roms
If you have a "Full Set," the audit should turn nearly everything Green (except very obscure clones).
Even with a full set, WinKawaks can be finicky. Here’s how to fix typical problems:
| Problem | Likely Cause | Solution |
|---------|--------------|----------|
| Game doesn’t appear in list | Wrong ROM version | Use ROMs from MAME v0.139 or earlier. |
| Game loads then returns to menu | Missing BIOS (neogeo.zip) | Download correct BIOS and place in roms. |
| Audio crackling | Sample rate mismatch | Set audio to 22050Hz or 44100Hz in options. |
| No input response | Controller not mapped | Go to Game > Map Controls. |
| "File is corrupted" message | Incompatible set (split vs non-merged) | Convert to non-merged using ClrMAMEPro. |
| Netplay desync | Different ROM CRCs | Both players must use identical ROM ZIPs. | This section is critical
Example entry in rominfo.dat:
Game "Metal Slug" (mslug)
rom mslug_c1.rom, 0, 100000, 5AD92CA7
rom mslug_c2.rom, 100000, 100000, 0B5EE583
...
Yes, but with caveats.
For the preservationist and the old-school gamer, having a WinKawaks full set ROMs collection is like owning a time machine that fits on a USB stick. The emulator is lightweight, boots almost instantly, and handles the most beloved arcade genre (2D fighters and beat 'em ups) better than any other software. The number varies, but a true WinKawaks full
However, be aware that development on WinKawaks has ceased. Modern alternatives like FinalBurn Neo (FBNeo) have larger full sets and better accuracy. But FBNeo lacks the nostalgic, "double-click and play" simplicity of WinKawaks.
Final Recommendation: Keep a WinKawaks 1.65 full set on an older Windows laptop or a Raspberry Pi (via Wine/RetroPie). Use it specifically for Capcom and SNK games. For everything else (Irem, Toaplan, Sega), use MAME.
The arcade era may be dead, but thanks to collections like the WinKawaks full set, the quarters—and the memories—live on forever.

For hardcore collectors, use ClrMAMEPro with a WinKawaks DAT file. This tool repairs, renames, and rebuilds ROM sets to match the exact checksums required. It can convert a MAME set to a WinKawaks-compatible set.
