There are none at this time.
Fortunately, Handango does have some software that look similiar to Asrtaware games.
The ones with the best graphics appear to be many of the Magmic ones. Those tend to run very fast and smoothly while still having reasonably good graphics. If you want the smooth running graphics.
Some people notice the Microforum games look remarkably similiar to certain Astaware games (i.e. Zap2016! PalmOS looks similiar to BlackBerry MegaBlaster) .... These have some rather fancy graphics but run slowly. Microforum seem to have somewhat fancier graphics but run MUCH more slowly...they tend to run VERY slowly, at least on a model 7280. Some people think they are unplayable, but I haven't tried them on the newer Blackberries (7290, 7250, 7520)
(I can't directly link to Handango.... Because Magmic is one of our sponsors, and I am posting screenshots of what are "competitor" videogames)
