After spending a lot of time thinking about the language, I came up with a relatively simple algorithm based on the language design - there are a few operators that mutate state, so basically just try combinations of those until your next memory cell contains the thing that you want, then lock those instructions in and advance.

Basically RNG yourself to victory.

The original code for that algorithm is here (python, + my own interpreter): https://github.com/wallstop/malbolge-toolkit/tree/dd942fb981...

I've since llmified it as an exercise.

BUT! The whole reason for this comment is to nerd say that printing stuff is relatively easy if you invest the time in learning the language's primitives and think of programming in it more as algorithms to operate on the op codes instead of literally writing code.

Now, to do more interesting things other than printing - I'd have to spend even more time thinking about the language, which I don't want to

Really? We had language machines for decades that couldn't do it. One that could was only built in the last 2 years max but that's something you expect from language machines? Lol Okay
