Kawaks Arcade Emulator
Kawaks Arcade Emulator is an emulator for Android that brings the quality and nostalgia of classic arcade games to your device. The app features a large library of console games from NeoGeo and Capcom CPS1 and CPS2, so you'll have plenty of choices when it comes to playing your favorite games.
This emulator is user-friendly and has a well-designed interface that's optimised for touchscreens and gamepads. It also includes advanced cheat code support, allowing you to unlock special abilities or modify game parameters for added fun and challenge.
If you're having trouble getting your games to work, check that the ROMs are in their proper folders. It's also possible that the emulator is too old for the ROMs, or that they were renamed or extracted (which can cause problems).
If your games aren't running correctly, try running the compatibility troubleshooter and following the wizard. It might help to install a new video driver, or run Kawaks in window mode (not full screen).
If you're looking for an even more powerful and feature-packed emulator, consider RetroArch, which has multiple 'cores' that can emulate different systems. This makes it easier to get older arcade games to work, and it's available for free. Just be aware that RetroArch can take a while to set up, and it may run a bit slower than Kawaks. You can house your emulators in "Documents", a folder on your desktop, an external HDD, or a thumb drive - just make sure they have full read/write access.
