Javascript running out of heap memory and cannot get it to increase

[TheGamingGallifreyan]

I have been attempting to decompile a ~300MB .rcc file but just keep getting this error after about 5 minutes of letting it run. It gets up to ~4GB of RAM and then dies.

I have been trying different ways to increase the memory limit using the --max-old-space-size= flag and 64 bit NodeJS but no matter where I put it doesn't seem to take it and still dies at 4GB. I added it to the command line arguments and as an environment variable but no luck. How do you increase the memory limit?

I absolutely dread every time I have to deal with a NodeJS project because stuff that should be simple always ends up being incredibly frustrating and taking days... I just want these image files man lmao
