[Coco] Noob 6809 ASM programmer looking for tips

[Ricardo M. Ferreira]

Hello again, and sorry for the late replies.

BTW, does anyone know if there is a framework for Coco games (with 
functions for keyboard / joystick, sprites, sounds, music, etc.)?

Thanks, Bill! I've visited your music page, it is a great resource! I've 
listened to a lot of Orchestra 90 songs, and was wondering how hard it 
would be to use one such song in a game. I guess I could "borrow" the 
player code and build the game with the "scored" ("compiled") song, but 
do you know if there is already a game or framework with source code 
available for this?

I've found your site previously via Google. It's been really useful 
already, and it is on my bookmarks. Thanks, Aaron! :)

Thanks for the tip, Stephen. I ended up using Geany, which I had already 
installed on my Linux dev. machine.

Added to the library. Thanks, Dave!

Mark, for the processor, yes, just a reference is enough, but I also 
need references for the Coco itself, such as memory map and interfaces 
(keyboard, joystick, cassette, ...). So far, I think I've got everything 
I need, but I'm sure I'll bother the list with other questions later.

 From what I recall, they seemed to be very nice, but I'm leaning 
towards OSS on Linux ATM. BTW, the website seems to be unavailable now 
("The website you were trying to reach is temporarily unavailable").


So far I've done a few tests using CMOC, a "cross-compiler for a subset 
of the C language": http://perso.b2b2c.ca/sarrazip/dev/cmoc.html . I can 
write the body of the program in "C" and a few important routines in 
assembly, so the coding & testing (with the XRoar emulator) are really 
fast: from Geany (the code editor), I can press 1 key to compile & 
launch the emulator with my code.

[]s!
