JohnYayas is offering a free demo version of spaghetti in the hingednewt website
try it out before you buy anything else and see for yourself if it fits you or not
i remember pangolin also offering demo versions, but it is not compatible with the riya lite
lds is compatible with riya, but i have not heard of any demo version
so, just search for as many demos as you can find prior to deciding
and use patience... assembling the projector was the easy part. understanding the software is the real deal here
