How to emulate X68K in Recalbox

[rockaddicted]

@acris cool and thank you for these tests. We'll add it to recalbox in the next recalbox version post 4.1 stable release.
@rtype thank you for your awesome work on libretro cores

@rockaddicted o/ thanks for this news!

[acris]

@rtype where are you ?

J'ai une question :

ma Configuration avant tout :

• recalbox 4.1 unstable (april 2017)
• microsd 16Go scandisk + 64 Go Nano Usb
• Gamepad bluetooth : i:droid con (style PSX gamepad)

pour le moment je peux démarrer un jeu avec le bouton Y et valider toutes les actions avec ce bouton.
Je dois brancher un clavier usb pour accéder à F12 (sauf que mon clavier n'a pas F12 c'est balo)

Y a t il possibilité de remapper les boutons correctement comme la version psp de l emulateur px68k à savoir :
bouton start -> launch game
bouton R1 -> menu F12

J'ai vu que tu avais essayé le cpu cyclone ça donne quoi ?

[acris]

What's news : https://github.com/libretro/px68k-libretro

• Add Cyclone CPU for arm
• Add Menu F12 to L2 joypad
• Few Fix keyboard

@acris c'est quoi le cpu cyclone ?

[acris]

@voljega

r-type dit : A noter cependant qu'il existe une version spécifique pour ARM utilisant le cpu asm ARM cyclone (celui de picodrive.
https://github.com/chiorex/px68k/tree/speedup qui doit être plus rapide pour les cpu ARM.

J'ai testé mais je vois pas trop de différence peut etre qu'un oeil expert serait requis.
Je suis aussi passé en full frame et le fps est entre 55.7 et 57

Hello
https://www.libretro.com/index.php/new-core-px68k-androidioswindowslinuxmac/

[azvarel]

amazing this new core, really great news, I hope to see it as soon as possible in the recalbox, of course this core has a difficulty that is not having the virtual keyboard, but you can play with it a lot.

[acris]

@azvarel
What is the virtual keyboard used for?

[acris]

@azvarel
I see your question on IRC.

you need to create playlist file with name :

Akumajou Dracula (1993)(Konami).m3u

with inside 2 lines :

Akumajou Dracula (1993)(Konami)(Disk 1 of 2).dim
Akumajou Dracula (1993)(Konami)(Disk 2 of 2).dim

and you must hide theses 2 files :

Akumajou Dracula (1993)(Konami)(Disk 1 of 2).dim
Akumajou Dracula (1993)(Konami)(Disk 2 of 2).dim

select each file game , select button > edit metadata game > hidden > ON

And If you need to optimize this game may you need to go retroarch menu (hotkey+B) :

Quick Menu > Options >

CPU Speed : 16 Mhz 
Game-Options File  to create file 
reset game.

And with px68 Menu (L2) need to chose frame skip : 1/6

thanks @voljega

@acris huh ? i'm always happy to be thanked but why in that case ?

btw scanlines aren't used by the X68k emulator at least in 'Retro' config is it normal ?
