Coco Emulation – Xroar – Missing Artifact colors – Workaround found

[dabone]

Has anyone gotten artifact colors out of the xroar port?

I can get the roms/programs started, I have set the -machine to cocous and the -tv-type to ntsc, but all the games have no color. The same games work just fine in my real cocos and xroar under windows.

(And yes, I’ve also tried pressing Ctrl-A many, many times.)

Thanks,

Maybe they are not supported on the rpi port ?

did you try both

--ccr simple

and

--ccr 5bit ?

(from the xroar documentation)

No change with either.

Has anyone else every tried the xroar emulator?

It seems it was launched a little early. The joystick config is strange.
It defaults to the second joystick for some reason, and the docs on custom setting it are confusing. I’d love to have some coco emulation going, but black and white on most games, just won’t cut it.

Downloading and compiling from the authors home page results in a working copy.
On the retropie version, the aspect ratio is wrong, and no artifact colors.

(after you compile it, and replace the xroar binary in /opt/retropie/emulators/xroar/bin

And copy the needed rom files to

/home/pi/.xroar/roms

we are building from the raspi branch which as native pi video output – it’s possible that the code is incomplete then – perhaps we should just use the plain SDL version if it works better.
