lr-mame2003 driver improvement and backport

i think someone was gonna create a dat to help in that regard.
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.

nvram doesn't get written out
Could you say more about what you mean by this?

Thanks man!! im going to add in support for a couple more games later and im plodding away on adding sound to another few, but im constrained
really by the codebase being 78 if it had been say 79 after all the CPU and Mem changes between those builds then far more could have been backported
as MAME 78 is missing support for alotta good Data East, Kaneko16, NMK16 and Sega games plus the Seibu Raiden Fighters Series.It would have been interesting to have seen how some of the above games might performed in this older MAME core but alas not to be as the code for
those is either not there not compatable or the workload needed just too great. -

@gamez-fan Hook up the recently dumped sound MCU
Unfortunately i cant do the same for Vimana as the MCU needs some input tag handling
not compatable with the MAME78 input code. -
WOAW excellent i love these games lol

@gamez-fan Rythm action games like Rock'n Tread are better with well music :)

nvram doesn't get written to disk.
Yes, under what emulator and circumstances? All retroarch arcade emulators should be writing nvram.

mame2000. Looks like the source version does indeed write it out now but the binary one needs to be recompiled.
Now if only we could get into the service menu or the usual MAME tab menu with just a controller...

@gamez-fan Hook up sound MCU for Vimana
Actually i spoke to soon it was possible to do this one without the input tags :) -

Thank you for checking on this. Could I ask you to post your experience trying to use the
TABmenu with source-compiled mame2000 in this github issue? https://github.com/libretro/mame2000-libretro/issues/25 -

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.
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.
I compiled with the change and it appears that retroarch is unable to load the compiled .so file that results from it:

if you can point me towards the sources then i can fix this. -

No go. Dumped my copy of the lr-mame2003 source and pulled down a fresh copy, made the change for DMA as we previously mentioned and compiled.

Actually, just noticed your change didn't yet get pulled so I applied it manually. The game loads and runs but even on my overclocked pi3 with resolution at 640x480, it seems to go back and forth between full speed and very slow (though audio sounds fine).

Open ice does the exact same thing on the Xbox with the DMA off but i noticed when i turned it on the game did get a slight boost not as much as MK2 or MK3
which is what i really use it for, i thought it was worth a try on the Rpi incase you got a better speedup via the DMA change but alas it was not to be which is a pity,
