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:

Yeah i just added a new driver dreamwld.c which will likely need to be declared in the overall sources hence the above compile errors
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,

I am able to play it with advmame 0.94 with my overclock and it's pretty playable there. Thanks for the help.

Hi ! First of all, thanks for your work !

I use retroarch and just saw in the new changelog that there is a Mame2003_midway core.
I found the site with the source but can't find the DLL
When i Update the core in retroarch section I only can see the tradionnal 2003 core but not the midway one.
Can you help me to reach this dll ?

Thx

Regards

@gamez-fan Thanks for all your great updates & patches.

I know I'm insisting on this as I already made this comment on github..
but is there any chance to get sound in "Deep Scan" (sega vicdual) ?
That would be so great!

Recently samples were added to another vicdual game (more info here). I asked if it is possible to add a similar "sample player module" to Deep Scan on that thread but no answer. Samples are available; they are the same as Depth Charge.

Lets get Fire Barrel playable : https://github.com/libretro/mame2003-libretro/pull/182

@gamez-fan Fix sound and improve the bad graphical layer, original code by BP and myself

I take it you mean this game it's the only one i can see called Deep Scan in the MAME78 vicdual driver..........

GAMEX(1979, invds, 0, invinco4, invds, invds, ROT270, "Sega", "Invinco / Deep Scan", GAME_IMPERFECT_SOUND )

It seems to have sound but your saying it needs to use the same samples as depth charge..?? it should be easy enough to hook it
to those samples in the driver if thats what the game requires i honestly haven't played this one.

Any chance the system16 games might get a fix? Shinobi has a missing audio channel in the 2nd stage, maybe other areas. E-Swat has garbled voice. Moonwalker won't load. I don't think Altered Beast is playable. Enemies don't move or something like that...it's been a while since I tested. Mame2010 plays most of them fine but some are unplayable because they run too slow. Same goes for latest fba.

Only gonna be the unprotected versions and bootlegs of these games which will work in this older Core, i've never bumped into any of the problems you mention above
when using MAME84 on the Xbox so im guessing a few MAME commits by Charles Mcdonald around MAME81-82 should sort all of the above it's just the workload required
my end to backport these changes that might be the sticking point.

I'll take a look sometime to see how much graft it would be but for now im taking a break from working on this source i have another xbox project im gonna be busy on
likely for the rest of the year on a seperate note i suppose this would be a good time to round up the Roms for all the new games i've added support for or hooked up
the sound in etc etc give em a whirl and let me know if they work correctly or not.

Cheers!!

Moonwalker won't load

I don't have the other, i think they don't work fine like you write, but Moon Walker (bootleg) is already working fine :)
Altered Beast working, but the scrolling is really slow, the enemies don't disappear ... it is not playable lol

For my part @gamez-fan i have try again the Gal's Panic serie, because you write me them works fine on MAME 2003, i use the official set and no more chance, i can't play them :(
The number 1 working fine, the 2, 4, S, S2 not launching and i play a lot to them on xBox without any problem :)
A friend tel me he can make the S2 working on his PI, he gave me his ROM and it not working better ... it is really strange ...

Im sure i read SH2 games have problems on this platform..?? Kaneko Supernova games use that CPU hence maybe why those versions of Gals Panic dont boot.

Edit daft question you do have the bios skins.zip in your Roms folder..??? these games require it.
