@tinyunknown156 The weirdest thing here is that you are gonna use a mame version from 22 years ago on a pi4 : the older the glitchier. While mame2003+ has a good balance between supported games, fixed bugs and performances on a pi4, the same is not true about the other vintaged mame cores from over a decade ago.
in addition to a working 1080p mode, which for you may be
ps, can you not SSH in to diagnose via another PC on the network?
Not sure which fixed it, but this made it work properly. It flickers a screen with the terminal/command cursor a few times quickly but i see it and then it displays the appropriate screen following that. So far i've gone in and out of config screens and reboots and it appears to be working now.
Now to fix the performance issues ;-) or i should say optimize. it runs fairly well. :)
I picked up a Vilros Pi 4 kit to use with VMAN's 512gb image. Consensus seems to be that one shouldn't use a prebuilt image, but I figured I couldn't go wrong with what was seemingly regarded as one of the best. And, so far so good!
We don't support 3rd party images. Ask the author(s) of the image for support, or use the image from retropie.org.uk/download.
@pedrovay2003 well the keys were leaked many years ago. Possible that they are in there. Or they have some hackey way of decrypting like the programs that will extract a clean iso from a bought pbp.
You may be the one of the very few people to attempt to run a DRMed file in an emulator, because for the most part, it should not work.
Also beetle-psx is practically the same emulator as mendafins.
@rbezares I had this a couple of days back, somehow es had managed to remove it self, I refreshed the card and it happened again, although got slightly further in the boot as es did appear before crashing. I flashed a new image to a different micros and it has worked fine since so am putting it down to a bad card
Did you configure the controller via Emulation Station correctly? Maybe do it again to be sure.
There's a script to assign controllers to players. It works very well for me. Maybe it's worth a try for you.
