Testing homebrew programs

There are two ways to test programs compatible with the WonderSwan developed using Wonderful:

• Testing using an emulator - cheap, convenient, not 100% accurate;
• Testing using physical hardware - expensive, rewarding, 100% accurate.

In general, it is recommended to test using an emulator, then periodically validate with physical hardware. Hardware verification is required in particular if you're relying on cycle-exact code or obscure tricks.
