LinkUniversal_real

This is a test ROM (based on BeatBeast) that checks how the LinkUniversal library behaves in the context of a 2-player game, with an audio player (in Direct Sound DMA mode) playing music, a background video, text and sprites.

The example sets the interval at around ~4 transfers per frame and sends 2 consecutive numbers on each frame. Each node validates that the numbers are consecutive, ensuring there are no repeated or missed packets. Also, each player can send extra packets to move the remote horse to the left or right. No audio pops should be audible on hardware.

As an extra option, support for LinkCableMultiboot::Async and LinkWirelessMultiboot::Async has been added to send a multiboot ROM asynchronously, while keeping the audio and animations running.

• A pre-compiled ROM is available in the Releases section.
• Check out the USERFLAGS line in the Makefile to see the selected LinkWireless build configuration.
• Check out the main.cpp file to see the runtime configuration.
• Uses butano 18.8.0 and gba-link-connection 8.0.3.
• Compiled with devkitARM, using GCC 14.1.0 with -Ofast as the optimization level.
• Check out the #licenses folder for details.

Alternatively, you can compile the ROM with Docker:

docker run -it \
  --user "$(id -u):$(id -g)" \
  -v "$(pwd)/..":/opt/gba \
  -v "$(pwd)":/opt/LinkUniversal_real \
  devkitpro/devkitarm:20241104 \
  bash -c 'cd /opt/LinkUniversal_real && make rebuild'
