MAME development: lr-mame2003 Updates

space invader

Oh, it's a pity!

Then it is imposible to play super sprint with more than one player? Or marble madness with two players?

I have correctly setup 3 mouses (2 trackballs and a spinner or 3 spinners) in advmame but I'd like to use the crt shaders of mame2003.

Finally could you explain me which is the usage of the last update? Is posible to map x-axis for player one and y-axis to player two??

This way at least could be posible to use two steering wheels...

@space-invader yes that's exactly what the last update allows. You need to enable the core config option. Check here for instructions. I have two spinners and it works great in Super Sprint and others. You can still map player three to joystick. No joy for multi trackball Marble Madness or Rampart. Use the spinnners and trackballs wiki I wrote for AdvanceMAME. It does have some screen effects--the rgb triads aren't as good as libretro shaders but it's better than nothing.

Solved! I had enabled the option but didn't know how to map the second player to the y-axis. After some hard thinking, up and down and it works. :)

dankcushions, any more improvements to come in your schedule??

Anyway, many thanks for your effort.

@space-invader my to-do list is in the first post.

I think using more than one trackball/mouse in retroarch MIGHT be fixable. I'll look into that in a week or so :)

@dankcushions , you may want to consider "fixing default aspect ratio for CPS2 games" to "all games" in Mame2003. I am finding that everything is outside of what it should be. Mortal Kombat plays stretched, Donkey Kong is not 3:4, etc.

dankcushions

@GreenHawk84 it's not everything, but there is a general problem. I gave cps2 games as examples.

I would enjoy to ship you a six pack of beer for this work.

It would be awesome! Waiting for your great job!

dankcushions

aspect ratio problems have now been fixed :)

previously some games would appear at the wrong ratio (eg blasteroids stretched, street fighter 2/alpha stretched, mortal kombat stretched). now corrected via https://github.com/libretro/mame2003-libretro/pull/53

you should now never need to use custom aspect ratios to get it to look correct.

Dude nice!!

Awesome work man!

I updated Lr-Mame2003 today via "source." I went to launch Battletoads and it is still stretched. Do I need to update again today to get the new update to fix it? Thanks!

thanks :) it was updated when i posted last (21 hrs ago) so i think so, as battletoads is approx 4:3 on this version (just tested)

BrockBoyts

@dankcushions So is the correct way to update Lr-Mame2003 in the retropie menu and update via "source"?

BuZz

you can update from binary - the binaries have been updated.

thanks! so i checked mame2010 out - it has the same issue and it should have a similar fix, but i couldn't quickly fix it as there's some annoying stuff in the way it was written. here's where i'd want to fix it: https://github.com/libretro/mame2010-libretro/blob/master/src/osd/retro/retromapper.c#L144

but the machine being run isn't initialised till after, here: https://github.com/libretro/mame2010-libretro/blob/master/src/osd/retro/retromain.c#L222

so really either the init needs to happen sooner, or the retro_av_info needs to be reset after the init.

anyway, i logged the issue: https://github.com/libretro/mame2010-libretro/issues/20

I'm not working on it right now but it's not impossible, just not much point me looking at it when there's stuff out there I can get fixed easier.
