Caprice32 supports M3U type playlists (.m3u) for multi-disc games. This makes it easy to switch between discs when needed using the RetroArch's Disk Control interface. Additionally, the SELECT + L and SELECT + R gameoad combinations can be used to load the previous or next disc in the .m3u playlist.

Joystick Controls Setup

As usual for a "classic" computer, a keyboard is needed for optimum input control. Flight simulators or complex building simulations require a variety of key combinations. For further input we need a connected (real) keyboard or a Virtual Keyboard. This can be called with the START+Y-Button of your PAD in lr-caprice32 (older versions < 4.5 make use of Y-Button only)

When we talk about joysticks, these are directly interpreted as cursor inputs by the CPC. The fire button is displayed as X. So if you press right HAT button a right arrow will be printed. So you see the CPC interprets the joysticks input as ASCII code, very unsimilar to the Atari 2600 or C64. But the devices use all a D-SUB-9 connector and theoretically even a Megadrive/Genesis PAD could be connected to this machines (afaik Start or Select button bridges 5V and Ground -- risk of a short circuit with possible damage to original hardware).

JoyPad setup for lr-caprice32

By default the RetroPad is selected as controller input, we have to select Amstrad Joystick to make the Virtual Keyboard work. Enter the retroarch core by using SELECT + Y on your pad, now use Retroarch -> Quickmenu -> Controls -> User [1-4] Select Device Type Amstrad Joystick and save the input mapping.

Now you can launch the Virtual Keyboard to configurate any game. If the overlay window seems to stuck then press Select-Button on your pad to activate it and move its white cursor with the HATs. A-Button selects the character.

JoyPad setup for CapriceRPI

Default keys: * Analog1 / HATs is cursor control * Y-Button brings up the Virtual Keyboard * X-Button brings up configuration menu (with possibitly for save state) * B-Button is FIRE (lr-caprice uses A-Button) * A-Button is character Z

CapriceRPI

If you are open into a ROM from EmulationStation and it opens to a blue screen you can type 

CAT
and it will list the file names of your game. The you will type RUN"FILENAME (match the lettercase exactly)

e.g. CAT results: 

CABAL     .BI1
CABAL     .BI2
CABAL     .BIN
CABAL     .LV1
Then I type: 
RUN"CABAL
If your keyboard types @ when you try to type ", then the Pi may be configured for the English (UK) keyboard layout, in which case you can type " by trying to type @.
