Look who’s back, it’s the undisputed champ in the classic console emulation-porting league; you know him, put your hands together for ZX-81. Download PSPHUGO v1.3.1 and you’ll be imitating the Turbo Grafx 16 or PC Engine all proper and stable like. And if you managed to pull one of these off, you’ll no doubt appreciate this version.

PSPHUGO v1.3.1 changes:

• This version of PSP-Hugo supports IRDA-Joystick box designed by my good friend Buzz (see http://buzz.computer.free.fr). Schematic and PIC source code is provided in contrib folder.
• Add “IRDA joystick” device support for both DB9 Joystick and Atari Paddle
• Add menu for IRDA joystick settings and keys mapping
• Add option to choose between IRDA devices (keyboard or joystick)
