Best cross assembler for multiple 6502 targets

[barnieg]

I'm slowly learning how to use DASM as its used by Batari Basic for targetting the 2600, I've been reading up on the basics of Atari 8-bit computer assembly (GTIA chipset) and find that I may need to use another Assembler such as X-ASM. So that my brain doesn't explode can I use one assembler platform for all 6502 targets? This introduces the following questions:

 

1. If an alternative to DASM is used can Batari Basic still be used?

2. Could I use the same set-up for Atari 7800 or even one of the Commodore Computers at a later date?

3. Slightly of tangent - Is Graph2font available for Linux or are there plans to open up the source code?

 

 

Maybe I'm naive in wanting to be able to reuse code, but even without that I would rather not keep relearning the particular syntax's/differences of the Assembler I am coding in.

 

Thanks

You'll need start-up code for each machine you target. The CC65 "C" compiler package available from http://www.cc65.org has start-up code for quite a few different 6502 machines.

Thanks for the pointer, I've found that some 7800 software has been written using CC65.

 

I expect I will end up using Batari Basic + DASM for the 2600 and CC65 + CA65 for everything else

 

Out of interest has any one here been able to port a 2600 game written in assembly to another 6502 target leaving the game mechanics relatively intact?

 

thanks
