Ok as long as the format/template is in the current state, you can import PNG kits for eternity.
@Sany023 nice detail here, my pc keyboard profile is the same with you. I only change W with E cause i need to push Sprint with middle finger and use the around fingers to press shoot,tackle,cursor change,through pass.
My transition in PC was also from FIFA 99/2000 to PES3 and i had a very bad gamepad, so i play all pes from 3 to 2013 with keyboard better than with gamepad.
Also i have a feeling that since PES 19&20 are more 8-D than 360¤, it is an advantage if someone can play with keyboard arrows, even better than the D-Pad cross of a gamepad, cause the moves are more precise. The only minus that made me jump to learn play with gamepad was that you cannot aim manually with the L2 manual modifier and that my elbows are injured more when playing with keyboard.
This just doesn't apply for pes15~18 were the movement is more fluid and close to pseudo360.
But 19 and 2020 have so strickt rails that make the movement almost 4-D or 8-D, so moving with keyboard seems as a big advantage, if someone can live without L2 manual aims.
