Here is one of the author's thoughts on compatibility with existing JagRISC gpu sources
Here is the link for those who wish to compile their own.Command line options are definitely different. But that's probably the
smallest problem for somebody who is interested.
The assembler syntax is more important, as I understand nobody wants to
rewrite his old sources. Here vasm is either compatible to Devpac (using
the "mot" syntax module) or optionally to the GNU-as (using the "std"
syntax module).
AFAICS Madmac is not compatible to Devpac. The functionality is similar,
but the Madmac directives start with a dot.
I am prepared [for feature suggestions and bug reports from the community]. The Atari ST scene already uses vasm a lot, because of the Devpac compatibilty.
