Hi,
I'm new in Casio Prizm Development and I want to make a game similar to this: https://www.youtube.com/watch?v=U1978S0khMc. In the past I worked with Cryengine 3, Unrealengine 2 and Java on the pc. Is it true that I need C++ knowledge and this PrizmSDK-0.3 for prizm games?

Thanks for your help and sorry for my English I'm from Germany.

Welcome to Cemetech, TiroTosh! Writing a tilemapper in C (not C++, because the released PrizmSDK is for C rather than C++) is pretty straightforward for the Prizm. All you need is an array of storage, some sprites, and key input to tie it all together. If you have experience with C/C++, then you should be able to learn what you need to know to write graphical Prizm games pretty fast. We're happy to help!

Also, no need to apologize; your English is more flawless than many of our native English speakers.

My port of openjazz jackrabbit utilized some c++ features. However yes you only need C knowledge and the only reason I used c++ was because this is a port. Also yes we are happy to help. I would also like to point out that it is better to use libfxcg in place of the old PrizmSDK 0.3. Libfxcg can be found here https://github.com/Jonimoose/libfxcg
