Two problems with retroorange pi

[SpeirsR]

Hello. First, thanks for your work.
I have a problem with the emulator psx and Tekken 3 NTSC rom. I put the bios in the BIOS folder, but when i run the game, i'm going to memory card manager (the game don't start). If i don't put the bios, the game start but run soooo slowly (unplayable).
The other problem is with lr-mame2003-plus. In the rom "Cadillac and Dinosaurs", the Coin button don't work. In other roms, i can insert coin with Select button without problems.

For the second problem, the solution was change the "hotkey" button. This way:

Manage Packages -> Core Packages -> emulationstation -> Configuration or
Configuration / Tools -> emulationstation

and choose the option to Clear/Reset Emulation Station input configuration

For the first problem, i think that the R2 processor is so weak.

Best regards.
