ehm .. what?!
you can play those games instantly! Just download them (not telling you where ;) ) and copy them to your psp.
If u've taken my release, copy them to x:\dosbox (this folder should already exist if you've installed my release correctly, put the folder of the game in there!)
Then, execute the prepared *.bat file, most likely called game_psp.bat (game = name of the game or an abbriviation of it) and u can play!
What do you mean with danzeff keyboard? a ready-to-use on screen keyboard for psp apps? Or what? DosBox uses p-sprint for now! CrazyC already helped us by implementing keyhint! be patient until he releases a version with an osk if you don't like the temporary versions.
I've made DosBox as easy to use as possible. You don't even have to type anything in order to get the games working! If u are still not pleased, I am afraid you've just have to wait then ... sorry!
