1	+	I wanted to play Sins of the solar Empire 2 with my friends. Proton and Lutris works great for SP, but MP was broke.
2	+
3	+	First blocker was [forcing](https://steamcommunity.com/app/1575940/discussions/1/7026264603287932608/#c7026264603289995255) the CPU architecture: (you can also edit this via ctrl+shift+s while in game)
4	+
5	+	The second was that there were desync issues, which the [community found and fixed](https://steamcommunity.com/app/1575940/discussions/1/7026264603287932608/#c7026264836515783746) for [other games](https://gist.github.com/reneklacan/7825b82723bf0534cbd2eae014e121ca). These desync issues seem to be fairly common with multiplayer games using proton. So you can always try this and copy the backup files back (.bak) if it didn't work. This version adds sha256 checksums of the .exe files. If you run into issues with "command not found", try `dos2unix steam_patch_mp_desync.sh` then retry.
6	+
7	+	The below script is a more agnostic version of the original script to be more generic and work with most games by passing the APP ID
8	+
9	+	```
10	+	chmod +x steam_patch_mp_desync.sh
11	+	./steam_patch_mp_desync.sh 111011
12	+	```
13	+
14	+	To get a list of installed apps run it without a app id
15	+
16	+	```
17	+	./steam_patch_mp_desync.sh
18	+
19	+	Provide a steam ID from below
20	+	1493710 Proton Experimental
21	+	1575940 Sins of a Solar Empire II
22	+	1628350 Steam Linux Runtime 3.0 (sniper)
23	+	1782120 ZERO Sievert
24	+	1794680 Vampire Survivors
25	+	228980 Steamworks Common Redistributables
26	+	250900 The Binding of Isaac: Rebirth
27	+	2805730 Proton 9.0
28	+	2828860 The Forever Winter
29	+	427520 Factorio
30	+	469600 Legion TD 2
31	+
32	+
33	+	example for 'Legion TD 2' would be ./steam_patch_mp_desync.sh
34	+	```
35	+
36	+	For deck users just override the `STEAM_USER` variable while running it if it doesn't default to the right user.
37	+	```
38	+	STEAM_USER=deck ./steam_patch_mp_desync.sh 11011
39	+	```
40	+
41	+	If you have additional drives setup in steam you'll need to set the full path to `steamapps` directory
42	+	```
43	+	STEAM_DIR="/mnt/games/steam/steamapps" ./steam_patch_mp_desync.sh 11011
44	+	```
