McZonk from Team Emergency Exit has updated his Commander Keen for PSP to version 0.99.Commander Keen PSP is a ported version of Katy¡¯s CloneKeen v8.3, which is an open-source remake of the good old 2D Commander Keen by id Software back in 1990. In this version, save and load is supported. Here is the message from Zonk:

Just a little new Version of Commander Keen for PSP. I thought I can release a final version but there are problems with episode 2&3. So it version 0.99 instead of 1.0. I hope to fix this bug soon. Or there next version will be 0.999 :)

Now loading and saving is supported. You can use the triangle to open save menu and you have 2 safe slots (left and right trigger). You can load via main menu (get back to main menu is also supported now).

Thanks to all old school gamers who love this game.
