I ended up deciding to just implement rolls up to 31, and then have a input reversing multiplexer to handle L/R

I guess LUT could work well, but it would be a ton of work to construct them.

And i think I forgot to implement a RRX. That's not gonna be fun to fix.

As a general rule of thumb, it's almost always better to use a LUT for anything. I mean... a single or operation between to operands would take one 8-1 mergerr, one rom and then an 1-8 splitter, or 3 nand gates. But a XOR would take the same merger,splitter and rom, or 4 nands. So even for this thing, a rom is better performance wise. The only situation were gates are better, is when you want to invert up to 2 lines, or and 2 ops.

Ill make a video soon about how to use them and how to think in state machines in general

I think it's time for me to try and build a circuit irl. It would help with my future copper board plans.

Thanks, but one more thing - would a rom be better irl? And if so, how can it be implemented?

IRL? Depends. I guess it's good for long term data storage or maybe help with niche operations and magic numbers. It\s like RAM, but takes nanoseconds to set and minutes to reset
