Homebrew Mame 2003 Plus

[markwkidd]

Am I correct that what WiiU users would like is to have -fsigned-char set as a compiler flag for mame2003-plus?

I have just made that change to the Makefile so that it will be part of the libretro buildbot versions of RetroArch. We already set that flag for ARM architectures.

Is there anything else that needs to be done to better fit the core for WiiU?

Awesome, can you share the new core download link ? I will test it tonight and let you know if the sound issue still there or not

I wonder, how a signed char or unsigned can cause sounds issues ??

mame 0.78 was originally developed with only x86 processor architectures and compilers in mind. It seems that by default the compiler for WiiU provides unsigned chars but that is not what the m92 is built to assume.

This is based on my guess that the same issue applies to WiiU as ARM, it is an educated guess but just a guess.

I don't know how to compile a standalone core for WiiU. All I can say is that the new RetroArch nightly download will include this change whenever it gets uploaded to the libretro webserver over the next 24 hours.

I remember I played and finished Spiderman on mame2003 on wiiu without any problem

which core do you use to play spiderman ? I try mame 2003 and I get DSI error unmapped memory ... I have couples of games displaying that error when I try to load them I dont know why..

Have you guys figured out how to get light gun games or steering wheel support on Wii Mame to work?

 

[Cecilmax]

I dont know why you need .dat i dont use these things. To find the roms im using here write on google mame 2003 archive

Hi, do you have any success running Zero Team game on FB Alpha ? On my side it run on Wii U but I have graphics garbage all the screen. I can press - to insert coin and hit start but graphics is completely garbage....

Great to see continuing optimizations on arcade cores for Wii, I'm doing some additional testing to see can we get a compatibility sheet going.
Question: is screen rotation implemented in these cores? I see that like many recent builds of RA, the screen rotation option (90 degree turns) in the Video settings is missing.
I see a TATE option in the core specific options screen but it doesn't seem to work, or at least I couldn't get it to.
Also is it possible to put back the game info splash screen like MAME 2000? The one that gives the board info and the screen resolution.
I find it's a very useful ready reckoner to manually switch to matched 240p/224p resolutions for CRTs on SCART.

Screen rotation is in video settings when you turn show advance menu to on

Ah yes, in Settings -> User Interface.
I never knew about it! Thank you so much @Cecilmax !

To see the Game Info screen with resolution etc you need to open the MAME menu. You can open the MAME menu by first opening the RetroArch "Quick Menu" and toggling the MAME Menu option. When you leave the Quick Menu you'll have access to the MAME menu.

Alternatively some map the MAME menu button to a controller button and access it that way. It's called the "game information" or "gameinfo"

Sooo.. about the question I asked that got ignored.. a little help please?

The Quick Menu on these Wii cores doesn't seem to have a MAME menu option.
Nor is there the ability to map that function to a controller button.

You can't, light gun is not implemented in retroarch Mame.

The Quick Menu on these Wii cores doesn't seem to have a MAME menu option.
Nor is there the ability to map that function to a controller button.

By default, you open Mame menu with Wii classic controller ZR. From there you can access game info. To remap to another button : Quick menu -> Controls -> Button 8.

Here's the source and a diff : mame2003-plus-0.3_source_code
I had issues compiling with the latest sources and devkit. There have been so many commits for 2 months...

I've uploaded a v0.3 based on the latest mame2003-plus for those who want to test. Midway games removed unfortunately...

 

[markwkidd]

You can't, light gun is not implemented in retroarch Mame.

That's not true in general -- mame2003 and mame2003-plus support multiple simultaneous lightguns.

Lightgun works fine via the RetroArch mouse interface and via the analog controls. I don't know anything about the Wii and WiiU operating system but if your device can be seen as a mouse or an analog device it will work fine.

On PC RetroArch I use a Dolphinbar with a Wiimote so that the Wiimote is seen as a mouse. It plays lightgun titles very well.

 

[Wiimpathy]

Yes, I know it works on PC. I meant pointer on Wii. Mouse emulation works on Wii with mame but only with analog/d-pad.

Thank you very much for sending the code and diff patch. It seems like it would be possible on first glance to modify the standard Makefile to include the split Wii cores. I'll be studying it!

Ok, probably one last little update because I'm a bit fed up with it now.

Mame2003 coreD

coreD test Source code

Sega32 and especially spiderman run ok. The v2 I posted was still slow or maybe I'm beginning to mix everything. Beware of the dol names, if you mix different versions, it could be an underscore(mame2003_) or a - (mame2003-). The bood.dol will return to Homebrew channel because of it.
It's a test based on a commit from march 27. Apart from the v60 workaround, the order of the drivers in driverwii.c matters. Right now, no way to make it work correctly in the latest mame2003 version.

Great, thanks for the update.
¿Any idea of why Dragon Ball Z 2 from Bampresto doesn't load?

 

[Wiimpathy]

If remember correctly this game has a protection that isn't (wasn't?) emulated in mame2003.

Another "a-HA" moment, thank you!
I'll have to start a wiki to capture some of these useful but cryptic settings areas.
