It sound logical, but it doesn't work that way.
Prety much every whdload game you can found has new icon. It is not easy to start those games with that bog standard icon wich is sized to 0,5mmx0,5mm. And there is also some games wich doesn't have event that and they crash system with KS2.0
He could use TinyLauncher or AGLaunch, I use TinyLauncher perfectly well on a 2.0 rom A600.
I never go into the icons to launch a game, even on my beefed up A1200!
Or he could use a file manager like dopus or filemaster or dirworks and add a WHDLoad button and launch his games that way.
