Build Reicast emulator on Ubuntu/Debian

build-reicast.sh

# NOTE: These instructions are old and may be out of date. A better alternative to compiling Reicast manually may be to use RetroArch with the Flycast core (https://www.retroarch.com/)

# Install prerequisites
sudo apt-get -y install build-essential libasound2 libasound2-dev libegl1-mesa-dev libgl1-mesa-dev libgles2-mesa-dev mesa-common-dev
# Build Reicast
git clone https://github.com/reicast/reicast-emulator.git
cd reicast-emulator/shell/linux
make

# Run Reicast
mkdir -p ~/.local/share/reicast/data/
cp ../android/assets/buttons.png ~/.local/share/reicast/data/
cp /path/to/bios/dc_boot.bin ~/.local/share/reicast/data/
cp /path/to/bios/dc_flash.bin ~/.local/share/reicast/data/
./reicast.elf

# To open a ROM
./reicast.elf /path/to/rom.cdi

# Key bindings
# Arrow keys: arrow keys
# A: v
# Start: Enter

@davidrc2009 I haven't used this in years but these days if I wanted to use Reicast in Ubuntu I'd probably just use the precompiled flycast core from RetroArch. Maybe I'll make a note indicating as much.

They are only 2 different lines.

Change
cd reicast-emulator/shell/linux
to
cd reicast-emulator/reicast/linux
and
cp ../android/assets/buttons.png ~/.local/share/reicast/data/
to
cp ../android-studio/reicast/src/main/assets/buttons.png ~/.local/share/reicast/data/

Thanks again,
compiling was the only way for me, because installing reicast via snap didn't work.
Cheers.
