Re: Couple of BeebASM usage questions.

For compact this could be done by including it's code to be assembled and saved seperately. However with format I want to be able to produce 40 and 80 track versions from the same code, which would mean including the format code twice, and re-defining the number of tracks (which I don't think you c...

Re: Couple of BeebASM usage questions.

Final part is that I'll need to put the assembled files for FORM40, FORM80, COMPACT etc on a single disk image that can be transferred to a real disk for use, I know it is possible to drop a single file on a DFS image is it possible to add files to an already existing image? tricky already answered...

Re: Mega Games Cartridge (MGC) MK II Development

I would also like some way to *not* have the cartridge auto-start the menu, so it 'just' provides an SD card interface and an MMFS ROM while leaving the Master to start up in the configured language as normal. A way to this would be to lose the option of a second SD Card Interface and use that pin ...

Re: Mega Games Cartridge (MGC) MK II Development

This is fascinating stuff (even if slightly over my head). If I understand correctly, this cartridge would provide an SD card interface which doesn't tie up the user port - is that right? If so I would potentially be interested as a way to add MMFS to a Master without tying up the user port. I'd wan...

Sure. Looking over the history o...

Kieran is right about the status of the stardot repo version of github (assuming nothing's changed since I last looked).

I think F11 is what I'd usually expect to toggle full screen mode. I say that mainly because Firefox uses it. That might be a bit easy to hit accidentally, but since F10 is break I guess it's no worse than that; F11 has no permanent effect, after all. I have no objection to Alt+Enter as a full scree...

Re: Do you own a Mac, and like your Electron emulators minimal and potentially seizure-inducing?

The logical next step is to add a technically-redundant glClear and see whether the window now at least fills itself in. If you fancy throwing a glClear(GL_COLOR_BUFFER_BIT); on line 294 of OSBindings/SDL/main.cpp then go for it. If that gives a window with empty contents rather than one that doesn...
