lr-mame2003 driver improvement and backport

darknior

If possible @gamez-fan it can be really interesting to think to this problem :

https://github.com/libretro/mame2003-libretro/issues/50#issuecomment-338385318
Libretro Overlay artwork is supported. Mame artwork supports also backdrop (Libretro does not) but only in the old .art mame format. This old format has issues in correctly setting artwork.
LAY format was introduced with Mame versions after .106 adn works great.
Could .LAY support be backported to lr-Mame2003 ?
Mame2010 does support it but it's way too slow on a Pi3 if you enable artwork. Even Space Invaders becomes too slow with full bezel and backdrop.

It can be fantastic to have that on MAME 2003 <3

@darknior thank you for your ongoing notes. I plan to create a new DAT for just the added/changes romsets once the changes slow down. Your notes are helpful.

@markwkidd Great idea!

Ok thanks it will for sure.
I will continue to test the games added to make report to @gamez-fan
I wish it will help to correct bugs.

For Neogeo all Roms and the Bios are still MAME78!! Except for the ones i recently added @darknior as i mentioned to ya on the github
use the NeoGeo Roms from your MAMEoXtras set for the newly supported ones.

Sound is not 100% in this one i just added it while hooking up the sound for Asura Blade in MAME78

Snowboard Championship Work (snowboar) - Impossible to make it load
Lode Runner The Dig Fight (loderndf) - Impossible to make it load.

What's the problem exactly..?? i need more info than the above ;)

Go Go! Mile Smile (gogomile) - Working fine

I had no input with the above game it's already supported in MAME78 but thanks for the credit anyway :)

Vasara 2 (vasara2) - Working fine but music is slow ...

Check Vasara for me please to see if that game also has slow music tempo.

Hey gamez. Great to see you over here as well!

Thanks for whatever you do on the Mame end. I'm afraid it will probably be quite a while until I get a pi 3 and do any arcade related stuff myself, but it's awesome to see that you're on the case. It's in great hands. :)

I'm lost, please can you list ROMs to use from MAMEoXtra ?

I can't really help, i launch them, i have the black screen like if the game will start, and it come back to ES.

What do you want i verify ? The game with MAME on PC ??

Just boot Vasara in this Emulator and tell me if the sound is slow in this game or not.

Yes but you have to do it via the dip switch options look for monitors and select A Only

PORT_START	// port F
PORT_DIPNAME( 0x03, 0x01, "Monitors" )
PORT_DIPSETTING(    0x01, "A only" )
PORT_DIPSETTING(    0x03, "A and B" )
PORT_DIPSETTING(    0x02, "B only" )

FIX - Might as well get Title Fight to work (titlef) - https://github.com/libretro/mame2003-libretro/pull/156

arcadez2003

The video above is from newer MAME where they totally broke the background Gfx, in MAME78 with the older video code it'll look more like this.......

Not perfect but better than having none at all :)

FIX : Optional Williams sound with the speedups : https://github.com/libretro/mame2003-libretro/pull/159

Removed in MAME61 these are the speedhacks that will significantly boost performance
in the following Midway games..........

All Midway Y-Unit
All Midway T-Unit barring MK2 which uses DCS sound

This could be of great benefit for users of this MAME core on lesser hardware. Drivers that will be affected by this change...

mcr68.c
midtunit.c
midyunit.c
williams.c
mcr_sndhrdw..c

Might as well add Puzz Loop 2 which was playable from MAME 93.u2, this is the last of the later CPS dumps which can be added to the MAME78 codebase due to changes with the XOR decryption handling from MAME100 onwards.
