USB Joystick Converter for Atari,  Amiga, Commodore 64

In order for you to use the old Atari, Commodore-64, Amiga joysticks on your computer, the usb converter circuit is based on the atmel atmega8-p circuit, which does not require an additional adapter for feeding. It works with 5volt in the usb port. The schematic was prepared with Eagle CAD. There are code files and matlab “make_table.m” file

USB Adapter for Gameport Joysticks and Atari, C64, Amiga Joysticks. JoyAdapter is for connecting an analog game port joystick or a digital (atari, c64, amiga…) joystick to the USB port. Firmware is based on MJoy project by Mindaugas Milasauskas, based on USB firmware by Igor Cesko. No additional software or drivers required – just plug and play.

Features:

analog game port supports joysticks and digital joysticks (atari, c64, amiga…)
no driver required
USB powered

Changes, Modifications:

– the interrupt pin is now connected to the “D-” line, because it is more resistant to electrical interference due to the 1.5 kOhm resistance.

– modified “INT0Handler” – removed possible deadlock if false interrupts occur

– modified “SendPreparedUSBAnswer” – level changes of lines “D+” and “D-” at the same time

– ReportDescriptor now describes a simple joystick with X/Y (8 bits) and two buttons that only export data in a single report

– The string reported to Windows is no longer limited to 4 characters (the solution to this problem was posted by “Grendel” on the USB-IF Developers Discussion Forum)
