OBS and DOFLinx

Text files for OBS

ArcadeDMD writes the values of the current game to the obs\ folder, one file per value. Each file is updated as soon as the value changes, and is emptied outside games. It works with MAME, Arcade64 and RetroArch.

File	Content
game.txt	game title
score_p1.txt, score_p2.txt	each player's score
credits.txt	credits (MAME and Arcade64)
fighter_p1.txt, fighter_p2.txt	character currently fighting, when known
streak_p1.txt, streak_p2.txt	wins in a row in VS matches (King of Fighters, once learned)
vs_p1.txt, vs_p2.txt	"BEAT BY 02" or "CHALLENGER", as at the top of the game screen
best_streak.txt	best streak of the current game, for example "BEAT BY 05 | P2 RUGAL | 26/10/2026"
vs_history.txt	one line per VS match won, with the date, the game, the winner and their streak
records.json	the best streak of each game, kept from one session to the next

In OBS, add a Text (GDI+) source, tick "Read from file" and choose the file. The texts are the same in every language. "P2 RUGAL > P1 KIM" means that P2 beat P1.

To turn this off, set "enabled": false in the textfiles section of config.json. "folder" picks another folder, and "history": false turns off the history.

DOFLinx bridge (optional)

ArcadeDMD can pose as DOF2DMD. DOFLinx then sends it the score and credits of every game it knows, with no address to look for.

1. In config.json, set "enabled": true in the doflinx_bridge section. It listens on port 8081, leaving 8080 to pixelweb.
2. DOFLinx reads the address from DOF2DMD's settings.ini (url_prefix). Set it to http://127.0.0.1:8081.
3. Do not run DOF2DMD at the same time, since the two cannot listen on the same port. When ArcadeDMD answers, DOFLinx no longer tries to start DOF2DMD.

The two sources complement each other. For After Burner II, the high score comes from the plugin and the score from DOFLinx.
