# FinalBurn Neo for Raspberry Pi
|
||
|
|
|
||
|
|
## Compiling
|
||
|
|
To compile the emulator, run `make pi`. You will need SDL libraries for sound
|
||
|
|
and input.
|
||
|
|
|
||
|
|
## Compatibility
|
||
|
|
Presently, the emulator will run on Raspberry Pi 1, 2 and 3. It will most
|
||
|
|
likely compile on 4, but will not run on it.
|
||
|
|
|
||
|
|
## Input
|
||
|
|
To customize joystick input, place a text file in a directory named `joyconfig`.
|
||
|
|
The file should have extension `.jc`, and named as follows:
|
||
|
|
|
||
|
|
```
|
||
|
|
<name of romset>.jc
|
||
|
|
<name of parent romset>.jc
|
||
|
|
capcom6.jc
|
||
|
|
default.jc
|
||
|
|
```
|
||
|
|
|
||
|
|
To determine mapping for a particular set, emulator will look for the first
|
||
|
|
applicable file, in that order. `capcom6.jc` will only be checked if the set
|
||
|
|
is determined to be a 6-button Capcom ROMset, such as SFII, III, etc.
|
||
|
|
`default` is a fallback file.
|
||
|
|
|
||
|
|
For instance, for set `sfau`, emulator will look for `sfau`, `sfa`, `capcom6`,
|
||
|
|
then `default`, in that order. For `mkr4` (Mortal Kombat rev 4.0), `mkr4`,
|
||
|
|
`mk`, `default` are applicable.
|
||
|
|
|
||
|
|
### Joyconfig file format
|
||
|
|
The format of the file is as follows:
|
||
|
|
|
||
|
|
```
|
||
|
|
<INPUT NAME>=<hardware joystick button number>
|
||
|
|
...
|
||
|
|
```
|
||
|
|
|
||
|
|
Input name can be one of: `TEST` (usually `F2` on keyboard), `SERVICE` (`9` on
|
||
|
|
keyboard) , `RESET` (`F3`), `QUIT`, `START`, `COIN`, or `BUTTONx` (where `x` is
|
||
|
|
a numeric digit between 1 and 9).
|
||
|
|
|
||
|
|
### Example
|
||
|
|
A generic `default` file could look as follows:
|
||
|
|
|
||
|
|
```
|
||
|
|
BUTTON1=1
|
||
|
|
BUTTON2=2
|
||
|
|
BUTTON3=3
|
||
|
|
BUTTON4=4
|
||
|
|
BUTTON5=6
|
||
|
|
BUTTON6=7
|
||
|
|
BUTTON7=8
|
||
|
|
COIN=9
|
||
|
|
START=10
|
||
|
|
```
|
||
|
|
|
||
|
|
In this case, buttons 1-8 on the hardware joystick map to emulated buttons 1-8,
|
||
|
|
while joystick buttons 9 and 10 map to "Coin" and "Start", respectively.
|
||
|
|
|
||
|
|
## Command-line switches
|
||
|
|
`-f`: Enables free play in games that include a Free Play dipswitch. This
|
||
|
|
switch isn't guaranteed to always work, since not every game has a free play
|
||
|
|
dipswitch, and because different sets may have the switch labeled differently.
|
||
|
|
`-F`: Enables free play hack mode. In hack mode, pressing Start also generates
|
||
|
|
a Coin button press.
