@james-anderson Hello!
Even if you have tried more than one extension, it is still possible that it is a ROM with some Bug.
Since the ROm is good, searching the forum, you find this topic:
https://forum.recalbox.com/topic/8753/bugs-graphiques-jeux-psx-xenogears/8
OR, translating with Google translator:
https://translate.google.com.br/translate?hl=pt-BR&sl=fr&tl=en&u=https%3A%2F%2Fforum.recalbox.com%2Ftopic%2F8753%2Fbugs-graphiques-jeux-psx-xenogears%2F3

And what is suggested by rockaddicted is:

delete the file: /recalbox/share/system/configs/retroarch/retroarchcustom.cfg the latter will be regenerated, so no problem. edit this /recalbox/share/system/configs/retroarch/cores/retroarch-core-options.cfg file, search for pcsx_rearmed and delete all references to it, save and exit.

You can do all this directly from the local network share (or ssh if you are comfortable).

"multipad" ? Did you mean multitap?
I've got the same issue with Tekken3 and BushidoBlade2 and it didn't help. It is strange because i was playing those games before an update.
Crash Team Racing is working fine.

@paradadf Thank you for your patient

Merci pour ce partage de fichiers :D.

@msilver

Danke für die Rückmeldung.
Ich markiere das Thema dann als "gelöst".

Happy Gaming

Bon je viens de tout réinstaller et en effet ça remarche nickel.

Thanks @barbudreadmon

@rocketman I also had problems with the PSP emulator on RPi3, and I've seen other reports about that, the "solution" I found was:
Go to the folder \share\system, in the file recalbox.conf, find the line "dreamcast.videomode =" and add just below it the line: "psp.videomode = default" (without quotation marks, obvious)
In addition, in the folder "\share\system.emulationstation", in the es_settings.cfg file, find the line "<int name =" MaxVRAM "value =" 200 "/>", and change the value from 200 to 80, getting : <int name = "MaxVRAM" value = "80" />
With this, the PSP emulator is able to work most of the time, and if the game does not enter immediately, just go back to the EmulationStation main screen, or wait a bit, to try again, that the game will start, without having to restart the Recalbox.
Some users reported problems due to themes with 1080p images, but others claim that even the default theme does not allow them to run PSP, so I do not know how much that actually influences (even more so because the info on this is more than 2 months ago.)
I know that @substring does not like my solution, but it worked for me...

@azkas tu peux aussi carrément sortir de l'émulateur avec hotkey + start et relancer le jeu.

@aragont33 super!

J'ai refais des essais hier et cette fois ça marche (la sauvegarde classique, pas le safe state) mais c'est surtout que j'ai commencé à jouer Dimanche dernier et ceci pendant plus d'une heure et après avoir sauvegardé, j'ai perdu toute ma progression car la sauvegarde avait disparu au démarrage suivant. J'avais peu-être, je ne m'en rappelle pas, éteint la Recalbox de la mauvaise façon. Dans tous les cas la sauvegarde marche maintenant. Même si le hotkey ne marche pas quelque soit la Rom, c'est déjà un moindre mal.
Merci beaucoup Idarius de t'être intéressé à mon soucis, c'est sympa de ta part.

Je vais essayer pour ma part de voir de mon coté les jeux problématique pour @zip64, si j'ai un retour positif, je vous en ferai part rapidement.

@profknt Kannst testen vielleicht mit Sandisk karte ? Manche SD karten machen einfach Probleme. Versuch bitte mit Sandisk karte. Habe keine wie von dir beschriebene Probleme bei mir.

@titocarioca Provavelmente ele resolveu achando as bios ONLINE, mas não poderá postar aqui no fórum, já que este tipo de material será considerado pirataria ;)

Faça sua pesquisa online para encontrar as bios.

@hetfield666 cool avec plaisir ; )

Besser einen USB Stick oder externe Festplatte. Kann man dann auch am PC anstecken und sehr flott seine Roms übertragen :)
