# cc65 Mouse Driver Demo

This sample lives in its own folder and builds a small C64 program with `cc65`.
It is based on the upstream `cc65` sample `samples/mousedemo.c`, but trimmed down
to a simple C64-specific example.

## What It Uses

- `mouse.h` from `cc65`
- the static C64 1351 mouse driver symbol `c64_1351_mou`
- the default `cc65` mouse callbacks for drawing the pointer

That means the mouse driver is linked into the program at build time, so you do
not need to copy a separate `.mou` driver file onto disk just to run it.

## Files

- `mouse_driver_demo.c` - the demo program
- `build.bat` - builds `mouse_driver_demo.prg`
- `run-vice.bat` - builds if needed, then autostarts the program in `x64sc`

## Build

From this folder:

```bat
build.bat
```

## Run In VICE

```bat
run-vice.bat
```

The demo expects the `cc65` tools to be on `PATH`, and it expects VICE 3.10 at:

```text
C:\Program Files\GTK3VICE-3.10-win64\bin\x64sc.exe
```

## Controls

- Move with the host mouse in VICE
- `H` hides or shows the cursor
- `C` centers the cursor
- `Q` quits

`run-vice.bat` starts `x64sc` with:

```text
-mouse -controlport1device 3
```

That matches the VICE 3.10 `Mouse (1351)` device with the program's default
`c64_1351_mou` driver.

## Using The Joystick-Mouse Driver Instead

If you want the joystick-emulated mouse driver instead, change:

```c
mouse_install(&mouse_def_callbacks, c64_1351_mou);
```

to:

```c
mouse_install(&mouse_def_callbacks, c64_joy_mou);
```

The `cc65` C64 docs say `c64_joy_mou` expects a joystick-emulated mouse in C64
port `#1`, while `c64_1351_mou` expects a standard mouse in C64 port `#0`.
