Alrighty! I'll keep playing normally, i'll install duckstation just to see it working
I installed the duckstation core, i tried playing the game there and swapping discs works perfectly, although it doesn't recognize the CD1 or CD2 extension i had to rename them as .cue files again and change the m3u to reflect the changes
I may have forgotten to mention but I've noticed that when doing a initial clean install of RetropIe 4.7 I noticed that with my 8BitDo controllers that there is a bug that does not allow me to configure the Right Trigger and Left Trigger . It does show up as a Xbox 360 controller, I had fixed that input by updating Retropie to current 4.7.11 and redoing the configuration.
@mitu thanks for replying .I was trying to get the x68k emulator swap-disks to work rather than the retroarch's . its odd that there are not any info about it on the internet! it got to be a common issue. anyways I gave up :) its seems retroarch is a much easier option now.
thanks again.your guides on this website helped me alot with the whole retropie/launchbox thing . I appreciate it.
