Change JVM paramters of modpack

[A.Stranger]

Hi all,

can someone tell me how to change the jvm parameters for the start of a the modpacks?

And please, please, please: don't say "version.json in modpack.jar".

I'm not a mod developer, just a normal user who wants so play the same modpacks on diffenrent computers with different jvm settings (e.g. socks proxy) and i rly don't want change always the modpack content of every mod.

 

Regards
