CrazyC has posted up a new binary of his Dos Emulator for the PSP, heres what he posted:
I've put up a new version that adds a new option to the sdl section called keyhint. When set to true, the first button press will display a hint about what key you will get with the second button press. If the key you want isn't there you can cancel by pressing cross. It currently flickers a bit, but I'll fix that soon. Hopefully this will tide people over until I can put a full osk in..Download links:0.71 patch 0.71 binary (rename to EBOOT.PBP if you have to) 0.71 conf file
