Any good examples?

Been thinking about making a game for 5200/XE, are the any good C libraries for me to use?

Not really and not sure if general libraries make sense on this platform. Read the Atari Memory Map, DeRe Atari and a few examples of games in CC65 e.g. here

If you use cc65 depending on the type of game i.e. action/shooter etc. you will likely still need

assembler routines within cc65, however cc65 makes this very easy to do as long as your happy

with 6502 assembler.

Also, cc65 will take care of creating a proper ROM image. So you don't have to learn that, and you can concentrate on game play.

If you are looking for a C-based software library for writing games, you could check out 8bit-Unity.  It allows you to target several 8-bit platforms in addition to A8 (c64, Apple II, Lynx), and it is based on CC65.  What's cool about it is that it does take advantage of platform-native features like hardware sprites, scrollable tilemaps and raster interrupts while implementing them in software on platforms that lack them.

I'm glad you brought it up...

 

I have some sound/music and graphics libraries in ca65, which I in turn call from games written in assembler.

 

I've been thinking of taking those libraries, and calling them from C instead. That way I can have the game logic in C, but the stuff that drives the graphics and sound in assembler.

 

I struggled a bit to figure out how to set up proper configuration with ca65, use .zeropage, etc. But once I got it working, I was quite pleased.

 

It sounds like there will be a similar learning curve (and not much sample code) getting a simple "Gr.0:?"Hello World" up in cc65!
