[Help wanted][Testers] Multitap Four Score support

[fjpolo]

⚠ Still in ongoing development ⚠

fjpolo/TangNano20k_Multitap is a branch in development that is supposed to support the NES Four Score by adding two additional OEM controllers. I got rid of the PS2 and USB controllers, to have more IOs, so it's a OEM-only branch.

I'm looking for testers with more than one joystick (I have only one) in order to test this branch.

What to do:

• Get the release bitstream: v20240320
• Flash the NESTang
• Follow the schematics here to connect all gamepad connectors
• Load a Four-Score game, legally obtained, to the SD Card root dir, like Micro Mages
• Start your NESTang
• Start the game
• Choose 3-4 players
• Press Select+Up to enable Multitap, LED[2] should be ON
• Test it :)
