The Binding of Isaac Launcher - Play DLC Separately *FINAL*
Hi guys!

One thing that's bugged me and I'm sure many others is the fact that you can't play the DLC content separately, instead having it permanently replace the vanilla version...that is, until now!

I present The Binding of Isaac Launcher (or The BOIL for short), a simple application that once installed will allow you to start the game from steam as per normal, however you will now have the option of turning off the DLC,

This is especially advised for newcomers to the game (and given the latest Humble Bundle I dare say there's a lot of you!) As the DLC adds a ton of new content that isn't by any means easier :P, besides, It's cool to see the vanilla game first that way you will appreciate and recognise all the changes :)

I have tested this as much as I can, both achievments and save games appear to be working as per normal, so don't stress about that!

Installation is straight forward, just run the installer, follow the prompts :)

Screenshot of The BOIL! []

Linux version is currently being worked on
Mac version is planned for after the linux build, so stay tuned!

Please report any bugs or feedback here :)


- Now correctly remembers previously played setting

- Now remembers previous window location

- Uninstaller now included, (a desktop shortcut will be made for it, for ease of access)

- Now checks to ensure that the install directory contains the game (this is due to the fact that the installer contains some files from the original version, so It'd be wise to ensure that people own the game and have it installed before this will continue installation)

- Launcher minimizes after game has started

- Optimised file cleanup after installation

No, as in Disk Operating System (I'm a vintage game nut :P)

i could launch it from desktop too , does it change anything where i install it ?
DosBoss Dec 21, 2012 @ 11:40pm 
yeah after installing it renames the previous isaac.exe in favor of mine, that way steam will launch it normally, in your isaac folder you should see isaac1.exe(normal) and isaac2.exe(wrath of the lamb).

could you please explain how this actually works, instead of distributing some random software? i don't even need the source, just a brief explanation of how you can switch between versions
DosBoss Dec 22, 2012 @ 1:01am 
sure :), sorry I should have done so last night,

Because Wrath of The Lamb replaces the vanilla version completely I first had to restore the original files, which then creates a second exe (as stated above), the launcher then just decides which exe to launch depening on the users choice.

After installation. a small batch script runs that handles the renaming of files (Which allows steam to launch it naturally).

The launcher runs in the background while gaming in order to track steam time, then closes itself after the game is exited.

Lucky for me, in doing research about TBOI before I decided to buy it, I read a lot of comments from people who hated the fact that when they bought the Wrath Of The Lamb DLC, it overwrites the old Isaac.exe file (without the DLC) with the new one (with the DLC). So a lot of people said that if you're going to buy TBOI, buy the original game first without the DLC, and play that for a while. Then when you have gotten used to the game, you can consider buying the DLC. However, before you buy the DLC, you should back up your Isaac.exe file first before you make the purchase. That's what I did before I bought the DLC. Once you have it backed up, then you can proceed with buying the DLC. After the purchase, the new Isaac.exe file will start downloading right away. So then, what you can do is rename your old Isaac.exe file to something else such as Isaac.exe.bak. Then put that file back into your "the binding of isaac" folder. Then, whenever you want to play the pre-DLC version, rename the DLC version to something else, then just remove the .bak extension from the other one. Save files that were made/updated with the DLC information will still work fine with the pre-DLC version. So the save files are interchangeable between the two versions. If the software made by ./DosBoss/ allows people who didn't know in advance that they should back up their old Isaac.exe file before buying the DLC, to be able to play the pre-DLC version again, that's great!

It does indeed allow that :D, go and install it yourself if you like, then you won't have to worry about renaming them all the time :)

Glad people are enjoying it

./DosBoss/, a lot of TBOI players have been waiting for something like this. You should really try to get the word out by posting about your software on TBOI section on the old Steam forums: Other places are The Super Meat Boy Website/Forums: And Edmund McMillen's personal website: Your software can very likely be a nice early Christmas present for TBOI players (who want the pre-DLC version back). Get the word out =)

Really? didn't realize something like this was THAT sought after!, I just had someone from a Binding of Isaac Reddit page contact me about this so perhaps word is spreading, if I get time I might do some advertising, who knows, users could already be doing it for me haha :P
