Probably asMSX will be included in the very beautiful MSXVR which is based on a Raspberry Pi board. Therefore we need to have a release cross-compilation for this architecture.

Do you mean it is able to run Linux ELF armel programs?
You can implement this build generation in Github Actions to make it universal :)

So, github is able to generate it directly? It would be cool that Github would build the release zips when a release is defined. Is this possible?

I'm now trying to add arm-linux-gnueabihf-gcc building step.

Rather than defining a new "step", you should be able to change CC and FLAGS by calling them in the make command or via environment. That's how the cross-compile projects are done.

And yes, release can be generated from Github Actions.

Cool! Two things:

Instead of none could we use linux? I learned today that none is to compile bare metal executables.

And, I would like to generate a new asmsx.arm or something like that, so that the make release build both.
