Nice work, which cores have you successfully compiled? Is netplay enabled?

This is the core list according to the Mednafen website.

Atari Lynx
Game Boy Advance
Neo Geo Pocket Color
Nintendo Entertainment System   
Super Nintendo Entertainment System (only available in WIP)
Nintendo Virtual Boy (only available in WIP)
PC Engine
PC-FX
PlayStation (only available in WIP)
WonderSwan Color
Sega Genesis (only available in WIP)
Sega Master System and Game Gear

It would be great to try the Virtual Boy on the GCW0.

Thanks david !
I have compiled everything i believe, even Genesis but i'm not actually sure. (i have not explicitly enabled it by default)
I believe i have enabled netplay as well but what purpose it could have on GCW0?

Virtual Boy works but unfortunely... :
  • Virtual Boy's resolution is 384x240, which is higher than the GCW0. (I'm not using the IPU yet though)
  • The V810 core is very slow, even when set to 'fast". That's the reason why PC-FX emulation is slow too.
  • Virtual Boy has two dpad : i could not set the 2nd dpad to the stick because i don't know what a stick config looks like

If you upload to guthub or something I could help you with the analogue stick issue.
Just set "X-OD-NeedsDownscaling=true" in the default.gcw0.desktop file to enable 384x240 res.

That's what i already did, it was called "Sauce repo".

Yeah, i know about that option NeedsDownscaling but the problem is that
Mednafen seems to do it itself automatically in software...
I need to find how to disable this.

The config file can be found in the release folder.

That's normal, it crashed for me too, i made a mistake in the config file.
Re-download it please, i fixed it.
Don't forget to update the config file too !

Tried a couple of PCE/PCE CD games.

Thanks a lot!

It's already much better than the other PCE emus.  :)

Sorry, didn't see the source code link  :-[

Looking at the config file, perhaps disabling scaling on the VB emulator may help? (line 8775)

I'll take a look at the controller code for vb. I'll push a patch to github when I get somewhere.

Mednafen-PSX core still crashes for me using QEMU... I know what I'm doing and it still seems to crash when loading CRASH BANDICOOT 2... the .bin or the .cue...

I have updated to the latest Mednafen core releases as of 10min ago. I have yet to try the mednafen core, but I am mostly interested in seeing if the psx core works as specified.

A question... where are we supposed to place the BIOS image files within the Zero?? I have them stored within the vFAT folder through QEMU. In other words, is there a specific folder where the 3 BIOS images are supposed to stored??

Thanks!

Yes, you should put them in /usr/local/home/.mednafen and not anywhere else or else Mednafen won't detect them.
MednafenPSX works for me here on QEMU

hmm.... maybe I am using a bad ROM image... I will try other games to see if I can get them to load properly.

How is the framerate of the games for the psx core?? playable?

Yeah, make sure your bioses are named properly.
Make sure you properly updated both opk files, including the config file !

As for the framerate, i was a bit surprised...
I used a homebrew game for testing but like i said before,
the bios screen and the game itself was pretty smooth actually, close to fullspeed.

EDIT: That was me being crazy... It was the Pc build here, not the GCW0 one lol.
PSX one runs at about 1 FPS, it's weird and it should run faster than that.

I can't check right now but I'd suspect PSX scaling is enabled in the config file. This would have a dramatic effect on framerate.
