This is an emulator hack that turns 1-player games into 2-player games by sharing in-game inventory over the internet. The sharing software is in the coop/ directory. A copy of snes9x-rr is included.
This currently works with Legend of Zelda: A Link to the Past; the Link to the Past Randomizer; and Super Metroid and its randomizer.
Open the ROM you wish to play. Then select File->Lua Scripting->New Lua Script Window. Click "Browse" and select "coop.lua" inside the coop directory.
Emu-coop communicates using Internet Relay Chat. You will get a popup asking which IRC server you want to connect to, what nickname you want to use, and what the nickname of your Player 2 will be. Once you're connected, tell your Player 2 to connect to the same network and enter your nick in their emulator. You should see either "Connected to partner", or an error message, pop up on your game screen.
If you halt a game in the middle and have to restart-- maybe your emulator crashed, or your Internet disconnected, or you died in Super Metroid-- you might "desync", where there are items that one player has but not the other. If this happens, both players should save, close their emulators, connect again, and this time check "Yes" for "Are you reconnecting after a crash?". This will resend all the data that emu-coop is tracking.
At the moment, you can run the script once per snes9x boot. On the second attempt to run the coop script it crashes. I don't know why.
You can add support for additional games-- or new modes for games emu-coop already supports-- by creating a .lua file and putting it into emu-coop's "modes" directory. If you add a new mode file, you will also need to add its name to the file modes/index.lua.
WARNING: Lua files are PROGRAMS, like a .exe file. A Lua file you install could give you a virus or delete files from your computer. Do not install a mode file unless it came from someone you know and trust.
The coop software was written by <[email protected]>. The "tloz_" modes (Zelda 1) were written by megmacAttack.
