Hello everyone~
I guess that retroarch RGUI language is set with system language on recalbox 6.1.
It work well in English, but retroarch RGUI font is broken to set system language in Korean. How to fix retroarch RGUI language to English with any system language. Thanks~

Hello~
The advance mame core of this recallbox 6.0 was slowed down. Games that worked well in previous version were slower in this version. The most popular games are Virtua Fighter and Numan Althletics 2. Can I move the advance mame core back to the previous version? I am sorry that my English. Thank you in advance.

Hello~ I use a nice recall box. I tried to apply XM-10, and it works well when 1P is set as controller. However if 2P is set, then 1P key does not work normally. Below is information about the joystick obtained with cat/proc/bus/input/devices.

How can I use this information to make sure that both 1P and 2P can work properly?
Thank you in advance, sorry for my English.
