Nice work Dank, you're really banging out the updates. Thank you! :)

I'm not sure if this this is a good place to mention a few games that don't work in lr-mame2003. A few that I think would be great additions maybe some day down the road. :)

Xenophobe which seems to work exclusively in AdvMAME no other emulators has this distinction.
Skull & Crossbones which works in all emulators but extremely flattened vertically in all emulators. Only AdvMAME seems to get the proper proportions. I use the video setting (672x 480s 1.00x2.00).
Puzzle Bobble (Bust-A-Move in North America) just drops back to the menu. It's the same in AdvMAME but for some reason mame4all-pi it does work.

@Riverstorm Most of the ones that don't work for me (add Rampage and Sarge to the list) have the same symptom: launches, but directly Service Mode and stuck there. I expect that's what others are seeing. It probably warrants another thread.

Nice work!

I can't wait to try this. Over the weekend I'll make some adjustments to the TrackBall/Spinners wiki page I wrote and extoll the virtues (again) of using lr-mame2003 for most games. At this point, only the most complicated spinner/TB setups require AdvanceMAME to map the inputs (and any vector games).

Oh, no Rampage. My nephew and I play a lot of Rampage. He's a teenager now but seems to like that one.

Binaries update - can hardly keep up! great stuff ;-)

I just loaded the new binary and set the core option mame2003-dialsharexy = "enabled"
It works a treat! I tried 2-player Blasteroids, 2 player Off The Wall (Sente), Championship Sprint, Super Off-Road and of course, they all work great using two spinners. I almost wish we had Pong in this romset!

Hi all!

I've been making some tests but I haven't been able to use two trackballs, one for player1 and another for player2

I have four mouses connected to the pi, and all of them manage player1.

How can I setup this correctly?

Many thanks in advance!

I think you are going to need AdvanceMAME for that. I believe lr-mame2003 is only going to recognize one mouse input, so all attached mice map to a common x,y axis. Recent updates enabled a setting to split these among player 1 and 2 but that's still just two dimensions on a single mouse.

I have four mouses connected to the pi, and all of them manage player1.

Yep. That's how it works. Try AdavanceMAME. You have all of the flexibility you need with that one.

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...

caver01

@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.

space invader

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.

@dankcushions :D brilliant

@dankcushions nice one! could feed that one to mame2010 also :-)
