Asura Buster (asurabus) - Working fine but i have an echo and sound play two times. No problem with FBA.

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

@darknior said in lr-mame2003 driver improvement and backport:

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 ;)

@darknior said in lr-mame2003 driver improvement and backport:

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 :)

@darknior said in lr-mame2003 driver improvement and backport:

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. :)

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.

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 ??

[darknior]

@gamez-fan is it possible to Outrunners single screen mode

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 - Make Air Rescue Work (arescue) https://github.com/libretro/mame2003-libretro/pull/157

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

[darknior]

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.

https://github.com/libretro/mame2003-libretro/pull/162

0.91: David Haywood increased interleave in MegaSys1 driver, fixing speed in Avenging Spirit.

[PeriodicLogic]

Two possibly very simplistic questions...

1. To take advantage of these improvements and backports, does one simply need to update lr-mame2003 from source?

2. Does one still use the 0.78 roms, or does one need earlier/later roms to account for the changes being made?

Thanks in advance,
Rob

I was really hoping that openice would be one of the games that would get these speed boosts. Oh well. Right now, it runs with slowdown on mame2003 and runs perfect speed on anything older but nvram doesn't get written out so it's useless.

Yes simply compile your own build from the latest source, all Roms that were supported previously are still MAME78 the newly supported games
will need Roms from later MAME builds i think someone was gonna create a dat to help in that regard.

Totally experimental as i found it can break the sound in some T-Unit games not using the DCS soundcore, which will require a workaround to sort
but just now for testing purposes if you can compile your own build in the MAME-2003 source goto src/vidhrdw/midtunit and do this.......

#define FAST_DMA 1 /* DMAs complete immediately; reduces number of CPU switches */

This should boost up the performance in Open Ice Challenge but enough to playable on the Rpi im not sure..?? you'll need to try it and see.

@gamez-fan Thanks, I'll give it a shot and let you know.

Once the codebase and ROM checksums stabilize I'll put together a DAT. ( @gamez-fan I enjoy periodically checking the mame2003 commit log to see you at work with backports!)

For now if people want to experiment they might try MAME 0.139 (MAME 2010) and MAME 0.106 (AdvanceMAME) romsets. There is a good chance they will match since they are from a similar period to the one where most of these additions are coming from.

Could you say more about what you mean by this?
