@heatseeker It is not so simple, dual boot with windows is very annoying, you have to redo grub, and originally the SHARE partition is not visible in Windows, as some imagine, because it is in a format that is only recognized by Linux.
The most complete tutorial I know is: https://forum.recalbox.com/topic/15678/dualboot-recalbox-windows-sur-pcs-laptops-avec-bios-ou-uefi
It's in French, but you can use google translator like I do.
If you google search, you'll find other tutorials too, but what I know is this. Recalling that developers do not recommend dual boot, for several factors, but it is possible.
I do not know the computer you're quoting, but are you sure it's compatible with Recalbox? I know the current BETA is getting very good, and very compatible, but I can not say it's compatible with the model you mentioned (I'm not saying it's not compatible, I'm making it clear that I do not know this computer model, and I do not know if it is), if you're sure it's compatible, great.
I did it a while back. I actually preferred to have it on my USB stick, for a whole host of reasons not really relevant for this thread.
Anyway, I am not in front of my recalbox, so I'm going from memory. I believe you need to go to system settings, select whatever recalbox lists as your hard drive, and you select it. Restart the computer back into your OS (Windows, for me). On the C drive, there should be a folder called recalbox. Place your ROMs in their respective folders in the roms folder. Reboot back into recalbox and your ROMs should appear. Let me know how that works for you.
Pour compléter la réponse, le paramètre primordial à modifier est donc la résolution interne ( EFBScale=4) dans le fichier GFX.ini
En changeant uniquement ce paramètre dans le fichier GFX.ini, on obtient une très nette amélioration sans trop de ralentissement.
Le fichier GFX.ini n’est pas modifié à chaque démarrage
EFBScale = 0 =>will give auto fractional
EFBScale = 1 =>will give auto integral
EFBScale = 2 =>will give 1x
EFBScale = 3 =>will give 1,5x
EFBScale = 4 =>will give 2x
EFBScale = 5 =>will give 2,5x
EFBScale = 6 =>will give 3x
EFBScale = 7 =>will give 4x
EFBScale = 8 =>will give 5x
EFBScale = 9 =>will give 6x
EFBScale = 10 =>will give 7x
EFBScale = 11 =>will give 8x
I went and checked again, and there were a couple of games that the reference to the bin file was .bin not .BIN. But editing them did no good and the games that had the extension in caps still worked in my internal memory. I know the bios files are there because I get the menu for the CD player for Sega CD and it will play music tracks from the game. It has to be something other than the .bin file extensions causing the problem.
