Does MAME even run on Pi4+retropie 4.6? And what happened to Mame4All?

@dankcushions - Ah ok, yeah if it's a bunch of extra work it's probably not going to happen. I do keep all the old releases around and several patched releases shrunk as tight as they will go to a few gig using virtual box and pishrink that would work for all intents and purposes.

The other thing that I find handy is having mame4all-pi as a reference test set so to speak. It gives you an alternative emulator to test ROMs if a Libretro core (2000 that also uses 0.37b5) comes into question due to several modifications that make it a Libretro core! :)

If mame4all-pi crashes then it probably never worked and isn't related to the Libretro conversion. Then you would need to fall back to arcadez, grant, barbudreadmon or one of the MAME code guys to potentially see if it's an easy fix in the core.

Plus you can't beat the size of that itty-bitty-tiny mam4all emulator, weighing in at few MB! ;)

If I remember right on the 3B+ I needed MAME4ALL for one game - Tapper and it had to be running the MAME 0.37 rom version.

not looked at mame4all didnt it have a sdl code path to work on windows and linux anyway? It shouldnt be a big issues fixing that if it is the case just the video needs reworked if there is enough people wanting it. it actually pretty easy to port mame078 to the pie as well.

@grant2258 In RetroPie, mame4all is actually a fork created for the RPI, using the native legacy GL driver - https://github.com/squidrpi/mame4all-pi.

This is a highly optimised version for the Raspberry Pi, using GLES2/dispmanx for graphics, ALSA for sound and SDL for input. It also uses the GPU for post-processing effects like scanlines.

im guessing anything using dispmanx will need reworked for the pi4 :(. Look like i was looking at the wrong repo the one i checked was here. https://github.com/RetroPie/mame4all-pi

That's a major drawback of mame4all, the scanline effects are a turd for sure compared to the Libretro shaders. =/

@grant2258 - I don't think there's much demand. I'm just an advocate of that lean, mean, little core. I even have a version that runs well on my iPad albeit the controls are less than optimal but thanks a lot for the considering it!

@grant2258 - The word wordspress has flipped letters.

Riverstorm

Sorry, to correct the link I mean.

@grant2258 The links doesn't work, but that's how almost everything works in RetroPie - we don't use X unless the emulator/game requires it.

I think it needs to be wordspress. Words is plural and then it worked.

grant2258

anyway there is a part 2 gles2 and 3 can be compiled and used without x

@ClassicGMR Tapper works in mame2003plus (not sure about non-plus). It also works fine in finalburn-neo but tapper.zip requires midssio.zip. What I do, is insert the contents from midssio.zip to tapper.zipso it doesn't clutter up my menu.

sirhenrythe5th

to make this list complete: Tapper also works wonderful with AdvanceMame ;)

Riverstorm

Just tested it and It does work in regular 2003 also.
