Hey there! I have the solutions ot all yoru problems, this is all normal behavior. A bit confusing but once u learn it is easy. Default settings, press the right CTRL key to swap the c64 joystick from port 1 to port 2 and back. C64 games work on either port 1 or port 2, seemingly random,. more on port 2, but still some o port 1, so u gotta try both if unsure. Also, if you 3ant to use thje ful real c64 keyboard, press SCROLL LOCK KEY. This will toggle the keyboard into real c64 keyboard mode, the shortcut hotkeys will not work inthis mode, so if u want to swap joy ports, u gotta toggle of scroll lock, then press right ctrl key, then tap scroll lock again.
Spacebar wil fast forward, great for load time, but againb, only if scroll lock is off when u press it. My advice I am using with RETRO:PAD default setting, using Xinput compatible pad, the 8bitdo SN30 pro 2. There is a project out there too now where people are ocnveerting tap and d64 images to CRT, cart files, and easyflash files, if u can find these, then they all load instantly, no need to type or wait, bloody awesome. There are around 2000 or so fuly converted games so far if u can fine the full set, not to hard with a bit of searching.
