I think yo need to buy some sort of licence to create on those things, which costs a lot of money. Also, not many people are interested in making games for handhelds, so it's not really worth it.
Who wants to work with me? We could start a company! and our product would be called
The U-KlikMan or something cheesy like that... the cool part would be that we would publish klik games and make HESystems so everyone could experiance the joy that is..klik.... (please note: this is a joke)
Joke or not, it could happen in the future. I know some here are crazy enough to make a portable klik system... Pretty cheaply too (guess $150) just have to make an OS that simply loads and runs .gam files...with linux..hmmm hey, that's actually a good idea..Anyone know how .gam files work?
If you wanted to know how .gam files work you should probably ask Dines, he knows a shitload about .gam files i think, he even made a topic about it in the forums here, you should check it out.
