[vg5000] vg5k improvement needed on mame/mess project
hi everyone!
i’m seeing that vg5k emulation on mame/mess emulator still lacks several features, like different ram sizes (expansion), .mrx dumps/snapshots, etc.
since mamedev is hosted at github by default - https://github.com/mamedev - i guess that would be great seeing these improvements soon
(btw, i’m not misregretting emulators like dcvg5k - the fact is that mame/mess is really needed of such improvements/features - and besides mame/mess is available in Debian/Ubuntu default repositories since years ago, the same we can’t say about dcvg5k )
thanks!

You're tempting me. I've wrote some MAME code for a driver almost 20 years ago... time goes fast.
My todo list is already so long already...

From what I see from the MAME code on GitHub, there seem to be a 16kB and 32kB extention option.
The emulation seems pretty complete. And as Daniel is credited as helper, it's a sort of seal of quality

Code : Tout sélectionner
~> mame vg5k -ramsize 48k
At least this seems to work. You can choose 16k, 32k or 48k.

i didn’t know that "-ramsize 48k" argument, thanks! (and i thought that it was available at the "tab" options)
but anyway, .mrx snapshot/dump support is still missing, isn’t it?

Re: [vg5000] vg5k improvement needed on mame/mess project
i think that there is a bug found on multicolor display - it shows quite differently among mame/mess and dcvg5k - i’m afraid that what dcvg5k shows is closer to the real machine

Re: [vg5000] vg5k improvement needed on mame/mess project
This is surprising, because MESS code for EF9345 emulation was copied from the dcvg5k sources.

Re: [vg5000] vg5k improvement needed on mame/mess project
results looks really different, it is really worth trying... - i guess we might need to do some kind of “bridge loading tests” for that...

Re: [vg5000] vg5k improvement needed on mame/mess project
perhaps that code copying happened before some probably recent bugfixes on dcvg5k - i have no idea about this because i didn’t follow the development evolution of both that closely, but it seems quite likely that happened this way...

Did you tried on a real VG5000 ?

Re: [vg5000] vg5k improvement needed on mame/mess project
i think i’m seeing what is happening - the mame/mess version i’m using is from ubuntu 16.10 repository, and it might be quite outdated - actually, http://i.xomf.com/cpvvj.png and http://i.xomf.com/zsjvj.png are from the same example i shared above

Re: [vg5000] vg5k improvement needed on mame/mess project
i created another example (source also included in the attachment as usual, i guess it explains clearly what i did)
on mess/mame: http://i.xomf.com/hsdbh.png
on dcvg5k: http://i.xomf.com/hqdcm.png
please let me know which one is closer to the real machine, and if any of the emulators i used are not that outdated

I'll try to launch this on a real computer this week-end if no-one does it before.
