Warnel Chawpiovs (abbreviated as WC) is a card game developed by Wololo based on a well known cooperative board game, with full rules enforcement, to play solo or (ultimately) multiplayer.
Differences from the original game:
- Unlike Marvel Champions, Warnel Chawpiovs allows heroes to play their turn in parallel. This is particularly obvious in Multiplayer mode. This is intentional: although the rules of the game state that each player should play their turn one player after the other (and explicitly ask other players to activate abilities or play cards as needed), in practice, most people play simultaneously and synchronize verbally. Because this is a video game, it felt important to me to minimize friction on that aspect, and allow clients to play simultaneously. If you'd rather follow the actual rules and play your turns in order, nothing prevents you from coordinating with your fellow players.
- In Warnel Chawpiovs, minions attack in the order in which they appeared on the board, instead of letting the players choose the order. This is mostly a design decision for gameplay speed. It sometimes impact one's strategy but I felt the benefit was worth it.

Features
- Complete card rules enforcement capacity, via provided Scripting Engine. (see doc)
- Multiplayer Support (Work in progress)
Installation
- You will need a hacked Nintendo Switch to run this game.
- Download the binary and the pck file from Wololo.net.
- Copy them to /switch/ folder on the SD card.
- Launch it from Homebrew Menu (press R while starting the game, not applet mode).
If you are downloading from the GitHub releases, resources will be automatically downloaded when the game starts (and it can take a while), unless you provide a separate "core.zip" file with those resources.
User guide
This simulator supports the following cards from the original game (current total 7 heroes, 8 villains):
- Core box (5 heroes, 3 villains)
- The Rise of Red skull ( 2 heroes, 5 villains)
There is no tutorial included, and, although the rules are automatically handled by the engine, it will quickly become confusing if you are not already familar with the original game.
Rules can be found here. (if broken link, go to fantasy flight's official page, scroll down to "support/rules" and select "Learn to play"
For all intents and purposes, Warnel Chawpiovs works for a single player using 1 or 2 heroes. Other game modes, in particular Multiplayer, are hit and miss. The Multiplayer layer in particular is a disgusting pile of race conditions and I'm not sure I have the skills to fix it for now.
- Single Player Mode:
- 1 Player, 1 Hero: Generally works well
- 1 Player, 2 heroes: Should generally work, with the occasional glitch or game-breaking bug
- 1 Player, 3 or 4 heroes: mostly untested
- Multiplayer Mode:
- Multiplayer (2 players, 1 hero per player): The multiplayer mode... exists, but that's about it. It is supposed to work but in practice it's difficult to finish a game without running into a freeze, crash or race condition. To mitigate this, the host can try and click on the "force sync" option button to force other clients to reload the host's current board state.
- Multiplayer (Other cases): Not tested. Multiplayer isn't in a reliable state at the moment, so more than 2 players, or more than 1 hero per player, hasn't been really tested yet.
Hosting a Multiplayer game:
- The host needs to forward port 7777 on their computer/router. The rest should be semi automated.
- Make sure the host clicks on "host" before anybody else clicks on "Join", otherwise things start breaking.
Limitation:
- Responses aren't exactly supported. They're either treated as interrupts, or react to the internal engine's events in no specific order. It "works" except in tricky cases where order of events is critical.
