trscolor coco - xroar emulator does not start

[rogeriol]

hello,
lately i had the urge to install a coco emulator and play with it a bit - never had a coco but i am a contemporary - here in brazil the cp400 color was released around 1985.

unfortunately the emu doesnt start in retropie. the gray popup flashes a bit and then returns to retropie. tried ccc and dsk files. any hints?

sorry my keyboard has a wrecked shift - caps - no capital letters...

Did you modify the default config.txt file from the boot partition ? Which version of RetroPie did you install in the beginning - the 4.6 image is not based on Debian Stretch ?

hi, i didnt modify anything manually, except some retroarch configurations. i am a basic linux user...

i believe i have installed v4.5.1 originally, and have been updating the script regularly, only to update the emulators and retroarch. everything quite fine except this emulator.

i use many other computer emus, like linapple, sdtrs, uae, lr-x68000, lr-q88, x1, lr-81, etc.

It's an emulator issue, with the latest version. For the moment, you can workaround it by editing the emulators.cfg file in \\retropie\configs\coco and changing the line

xroar-cocous = "/opt/retropie/emulators/xroar/bin/xroar -fs -vo sdl -ccr simple -machine cocous -run %ROM%"

to

xroar-cocous = "/opt/retropie/emulators/xroar/bin/xroar  -vo sdl -ccr simple -machine cocous -run %ROM%"
