Could you say more about what you mean by this?

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...

Thank you for checking on this. Could I ask you to post your experience trying to use the TAB menu 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:

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,

zerojay · 9 Nov 2017, 19:45

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
